- The Elegoo Saturn 4 Ultra is without doubt the most innovative printer they've produced... but that doesn't mean they haven't made some very stupid mistakes. There's great ingenuity here... but did they get it right? Here I take an honest and balanced look at this exciting new 3D resin printer.

I have to side with elegoo on separating out the heater. My printer sits in a fairly well-regulated room, temperature wise, and I've got nothing to gain from adding a heater to my printer. I'd imagine roughly half of resin printer users are in a similar boat, whether due to their setup or locale. It just makes sense to separate out that functionality, rather than incorporating the cost into every single printer sold. Elegoo's been the primary force driving down costs in hobbyist resin printing since the Mars 1, and I'd have to imagine a lot of careful cuts and consideration went into being able to put the 4 Ultra out at $400.
That's a fair point... but I have a couple of Australia buddies who have no issues printing in the day, but find falling temperatures a night a big problem. However, I appreciate not everywhere is the same - and I'm a little biased on this particular subject 🤣😂🤣
I was getting failed prints for weeks inside my fairly warm house.
Thanks to Vogman's heater project, I have rarely had a problem since.
Temperature is more critical than a lot of people imagine.
My printer sits in the garage so a heater is desperately needed in the winter.
@@vogmanthat’s why I have a mini enclosure with a full on proper heater
I wouldn’t buy a printer without a heater.
If they wanted to reduce the price they should of got ridden of that useless camera.
Great video.. minor note. The Camera is accessible by Chitu Free (the only chitubox I use), including the resin timelapses
Thanks for clearing that up buddy. I wasn't 100% sure. Now if only I could get it to work 😁😁😁
They definitely seem to have a 2 step forward 1 step back philosophy, but progress is progress nonetheless. Great video as always!
Yes, that tilt release is impressive.
Great review!
What's the time required on your other machines for the Goblin head? As comparison between different printers I mean, that's more interesting than the specific mm/h calculation imo.
The Prusa SL1 has been doing the tilt-release thing for years now. About time someone else did it.
Saturn 4 Ultra, What type of screw do you use on the main plate movement feed? Ball bearing screw and nut or plastic slide nut and regular trapezoidal screw?
Great review VogMan appreciate your input and this printer sounds like a winner and I am wondering where would one install the carbon filter and the mini heater ? Thanks for the review.
Nice review, I preordered one yesterday. Will be upgrading my halot lite.
Hope you enjoy it! 😁
What type of primer would you use on build plates to help prevent failed prints?
All power and USB accessories should be in the front. Why they place it on the sides or the back is beyond my thinking. People want easy access. Great review mate. All the best.
Absolutely!
Until you get a drip down the front and ruin a port
@@Jstubbs104 Well UNTILL that happens, will worry about it at that time.
@@LSCModels It also becomes inconvenient when you count for being in front of your printer.
Elegoo had the usb ports and other accessories up front, but resin dripping and fep failure the ports were getting damaged. They moved them because they learned from people before. I have a mars pro and an og saturn and I see exactly why they did what they did.
The missing heater is a major oversight. How much of the vat rim remains outside of the chassis when it tilts though? I would be inclined to use one of the belt style vat heating means, but am concerned the belt might interfere with the tilt.
@11:30 I always wondered what you look like... :)
Still not built my furnace which is based on yours but without the lift, I will lift the crucible instead. My MYPIN TA4-SNR controller died, shows as power off/on but it never cuts the power to the SSR. It's always switched on. Having trouble finding a new TA4-SNR. :(
Not been watching much lately and have an original Elegoo Mars. What would you put your own money on at the current moment in time? Speed not important a bigger platform is a must though. Thanks for all your work..
What a treat!!! Sitting at work mindlessly doing reports when this beauty shows up! Literally the video I’ve been looking for!
It was either this, the A1(in may) or the p1p. Eased my mind a little but still not sure where to pull the trigger.
You're comparing FDM to resin, which do you need first as the higher priority is the question, the other comes later, because they are not comparable.
@@cenciende9401 I am not comparing them, it’s simply a quandary of a decision.
I’d honestly love to have a resin printer but with such a small room that I have to work with, the fumes are a big concern for me. It might be my deciding factor honestly.
I’m strongly considering the p1p or s because I want to make pieces for cosplay and the bigger platform surely would help.
Kind of surprised they've beat some of the other manufacturers to the market that were/are also working on tilt-screen solutions. Not having a heater is a bummer I agree on, but the price is highly competitive. The community that doesn't need a built-in heater versus those that do for location-related weather is decidedly small, though I suspect it was off-loaded as an extra for that reason (get one if you need it kind of thing) even though where it plugs in to actually be effective on the resin is a bit of a mystery.
That all said, I'd be tempted to pick one up despite my historical stance on Elegoo at least for summer-compliant prints.
How high is the printer itself when flipping up the lid? (I mean the max height)
This machine is looking seriously impressive for the price! The Timelapse footage from the AI camera looks great as well from other videos I have watched… I have read a lot of criticisms for the Tilt release being an extra “fail point” but the feature makes sense to me.
Great video as always VogMan!
I think I’ll be pre-ordering this one.
Thanks for watching 😁
Thanks for your videos! They are very fun and informative! I'm thinking about changing printer (I have an anycubic photon SQ), anything will improve what I have xD and I'm thinking if the saturn 4 ultra or the anycubic m5s pro, both seem good options but the elegoo seems better for the new features it has(I think)...
Thanks a lot VogMan!
was looking forward to this printer but after many review videos from people who dont want to upset their free gifts and are lying about the issues plus the fact that the screen has only 2000 hours use, no heater and feels like creality buggy firmware then im going to give it a hard pass
thanks for your last 2 reviews VogMan!
I am secretly in love with the Revo right now, but I try not to let that bias my reviews. As for the M7, I believe I have one on the way, so who knows 😁😁😁
@@vogman We are also waiting for a comparison of 3 new printers (:
Sorry... they all come at once.
@@vogman Indeed, companies suddenly launched their products on the market. Things got very confusing(=
The lack of a heater is no deal breaker for me. I do all my printing in an unheated garage, so I put my printers in insulated grow boxes with a ceramic heater inside. I was able to print all winter long with temperatures sometimes in the 20s F with no problems. A quick trip to the local hardware will take care of the lack of a handle on the flip lid. I plan on adding a Saturn 4 Ultra to my "factory".
There's nothing wrong with fixes and workarounds - that's something I love doing. But my job here is to observe potential issues so folks know exactly what to expect when their purchase arrives 😁
That and the heater is $55 on their website - you can by one and still save hundreds from a GK two.
It does seem to me that the tilt release is more about making the print less likely to fail due to sticking rather than it being all about speed. But Prusa's SL1S SPEED printer featured tilting and the marketing was HEAVILY about how much faster it was. I feel this is more of a marketing focusing on the wrong aspect rather than it being outright silly. I would love to see a comparison on if the tilting mechanism means I don't have to have as many supports on a floating model, because the forces exerted on the model are not as extreme. This would be huge.
I'm like, wow, this is basically a Creality product, with how many things fall in the "oh, I'll need to make one of those for that" category.
Outside of a handle, what other things would you need to make?
Great review! Between the Saturn 4 Ultra and the Anycubic M5s Pro , which do you think is a better option?
This might help 😁 www.vegoilguy.co.uk/3d-resin-best-midrange-printer.php
if i get one of this prints ill have modded the software to allow it to work with lychee unsure if I'm gonna get one though still wish theyed give us this with the 8k screens
The tilt release is the most exciting thing ever for me as a Dice Maker because the huge pull forces make the dice elongate in this kinda non-linear way where the closer to the build plate you get, the more elongated it is along the Z axis (so you can't just squish it in the slicer to compensate), this elongation then has to be corrected by sanding the dice while applying force at an angle, very carefully, and even with hundreds of dice made, it's still hard and I can't get them perfect, only prints with a Form 3 come out without this warping, thanks to the tilt release.
But seeing the mechanism Elegoo is using, it worries me that the pushing up against the print before pulling down might actually make it worse in a different way. It also worries me that the Tilt Release is marketed exclusively as a fast printing thing, it might just really not help with dimensional accuracy at all.
Also It makes me worry that the whole mechanism might wear out and develop some wiggle room, bringing the alignment of the screen with the collimating lenses into play, and causing a loss of detail. This wasn't a worry in the Form printers because of the lack of a screen, obviously.
I have the same concerns about the tilt mechanism. Usually anything that moves a lots, wears a lot. But it's way too early to say anything about this yet. It's a great feature and I applaud Elegoo for it 😁
The tilt release is a wonderful thing if done correctly, like in the Prusa SL1S SPEED 3D printer, which is open source for years. I tink Elegoo might just found it finally :D
Maybe the STL can be scaled nonlinearly by hand in blender on the Z axis to account for the elongation?
I've owned machines with similar mechanisms. They're fine when they work but moving parts introduce another possible point of failure. The machines I have eventually had issues returning the platform back to zero/home consistently. In both cases this mechanism was the first thing to fail. Personally I'm not a fan, but maybe elegoo has a more reliable solution.
Only 10 years behind everyone else huh, I built in that feature on first home made DLP printer 12 years ago! the first Formlabs form1, which i still own, had it, and again, that was also a standard affair a decade ago.
Ordered mine the minute it went live. The LCD screen on my S2 went out a few months back, and I never replaced it.
Enjoy!
i will wait for the photon m7 ... seems like it has a heated vat and top speeds...
but the lifting function of the saturn is also very interessting...
Also I think it's interesting that once Elegoo announce the Machine was first going to be $399 Anycubic lower there M5s pro to $399 from $450 then Elegoo Raised the Price to $429.(actually US prices are still $399USD where as UK/JP are $429) so this machine is cheaper then their Saturn 3 Ultra in US which is kind of interesting.
That's why I hate listing prices. They change daily. It's a very competitive market.
Been waiting for this one!!!
I hope it was worth the wait 😁
do you have any plans to review the formlabs 4 printer?
also there is a new Micron Desktop SLS 3D Printer. 3,000$. in june.
I have a form 3, and a Saturn s. I had the form 3 first and used it regularly until I got the saturn s. My prints are sharper, faster and use cheaper resin than the expensive proprietary resins from Formlabs. My point is I ‘m not sure what the heck Formlabs is thinking charging what they charge for their products. With other companies doing better than them at a fraction of the cost, I am wondering how many of those $4500 form 4’s they will be able to sell.
@@julythrunov They're targeting corporations, I think. Hobbyist want cheap and open. Corporations generally want reliability and support. Tinkering around to get a printer working is a waste of money to a corporation when that employee can be doing other things that make the corporation money.
What about debris detection for not breaking the lcd
Good review, I appreciate the clear view of the quality and speed. The automatic leveling actually woking is pretty nice, but the comparison to the M5S is not flattering when considering the possibility of the tilt release mechanism slowly degrading.
Yes, mechanical parts do wear over time. The question is, how long will that take?
What's it going to matter many years and thousands of print hours later when you're upgrading anyway?
I've seen another revue where resin drops were spilled inside the machine and on the camera (probably because of the tilt mechanism according to the tester)... you didn't have any issue like this?
I'm a little concerned with the additional mechanisms involved in the tilting vat. Just one more integral aspect that could go wrong. Changing out the screen and fep is one thing, how do you feel about this component possibly breaking and needing to be replaced?
I'm always wary about mechanical moving parts too. Time will tell I guess.
Use 3d printer to make new one. Jokes aside, its looks quite sturdy.
Weirdly the M5sPro is the same resolution (if you look at the pixel size) but has less Z height, so this is actually looking like a good proposition. I've long been a fan of the Anycubic RERF functionality, so to see something similar *finally* showing up on a Elegoo machine is glorious.
The 12 and 14K issue is a weird one. The 14K improves resolution on the X, maintains it on the Y, I think. The difference on paper isn't worth worry about. However... look at the photos. I've done two 14K printers now. Compare the prints to the 12K's. Maybe it's me, but I swear the 14K's are smoother and just as detailed... the voxel lines are harder to see.
That's why I take the photos, so folks can judge for themselves 😁😁😁
And the RERF thing... brilliant idea. Every printer should have one... that works 😁
I suggest you to verify the dimensional accuracy. The tilt mechanism should give much more precise dimensions without that stretch effect that all resin printers gives on z axis.
i recently got he saturn 3 utlta and was supper bummed I didnt expect a new version a month and a half later. honestly even though it has some really nice quality of life improvements like the newer hopefully better poor spouts and flip up lid I am happy with the 3 ultra now. i feelthey missed the mark not having any sort of heater weather It was chamber or vat and I didnt see a spot to run a power cable to have a addon heater. I'm sad to see they didnt go a deeper vat and a skirt for build plate like the gk two that way you dont get resin ontop of he build plate. im curious about the tilt to release if it will distort the print making ti tsightly taller up front vs back. im sure it will help reduce the suction forces though
Never worry about missing an new version. There'll be another one out very soon, that's just the way these companies go. Enjoy what you have. I made some fabulous prints on the S3's.
Don't have a saturn 4, but with my 3 ultra, I got those high speed print when I used the included Voxeldance Tango slicer software. It has a builtin profile for it.
Hey what kind of speeds are you getting?
I'm so glad you didn't tell us all that it's the best low-cost mid-size resin printer by far. (I've just bought the M5S Pro)
Although that tilt plate sounds like a great feature, I don't have buyer's remorse. Phew! 😊
Thanks for another balanced review. Cheers!
ps. I added 1cm silicon feet into the foot contours on the M5S and it's far more stable and less noisy now.
Never have buyers remorse, especially with printers. These update much too quickly for anyone to keep up with. It's not worth trying to. Be happy with your decisions and enjoy your purchase 😁😁😁
Today would you buy the Saturn 4 ultra, or anycubic m5s pro? I read some people complaining about problems with anycubics, and I'm worried 😬😬
Saturn 3 Ultra
Elegoo Saturn 4 Ultra or anycubic M5S Pro ? the best ?
Thanks for the brutally honest review 😂😂 i really enjoyed it 😁 Great content as always. Keep it up!!
Honest and to the point as always 😊.
Many thanks 😁
Interestingly, they took some features from the original Prusa SL1. That was my first mSLA printer and it had a tilt mechanism, no lifting. It also came with a slop trey that was gross to use 😅.
Shame about the heater here, I thought I found my next printer!
The resin vat looks better than the one on the Saturn 3 Ultra - is the new resin vat for the Saturn 4 Ultra backward combatable?
Any word on the ACF release on this one? I was watching some old videos from Fauxhammer where he complained about the ACF smoothing details but then it wasn't the case on the Saturn 3 ultra
Well from my observations ACF liners were producing vertical lines on prints, and I've noticed that manufacturers have stopped fitting them, so I'm not sure.
Will you be making the top contenders for this kind of printers, aka this printer, Phrozen Revo, Anycubic Photon Mono M5S/PRO, GKTwo, etc? Sounds like they all use the same screen, just differing in the features.
Most of these printers use the same tech, though Elegoo stuck wit the 12K here where the others went 14. I guess the real issue is how well then put this tech to use. I have my own preferences listed here www.vegoilguy.co.uk/3d-resin-best-midrange-printer.php but I keep the videos as balanced and objective as possible 😁
is there an easy way to lube those bearings for the tilt mechanism? seems like something that should be addressed.
Not that I'm aware of.
Was looking forward to this review, thank you! I ordered myself one as I think it's a better fit than the GK2 for the price, since I'm also in California where a heater really isn't necessary for me. The rest of it seems so similar, I think I like the GK2s plate design more, but I want that tilting vat... And camera if it works lol.
Edit: Is this noticeably faster than your gk2 or other 8-14k printers because of the tilt function?
There's no doubt these companies copy each other, but if the end result is a better product for the consumer, and as long as no patents have been violated, then all's good I guess 😁
Honestly this makes me really excited for the Saturn 5 Ultra
That's next week 😉🤣😂🤣
Just ordered!
Best unbiased reviewer! Was waiting for this to decide between this and a gktwo. Seems theres good things in both, but i may plonk for the gktwo after all, good idea? 😂
Or get the saturn ultra and just buy the heater? I'm so confused 😢😂
Much appreciated!
I loved the GK Two, but it's showing it's age a little now, unless it's expanded to 12K like mine was.
Great video as always with excellent constructive criticism but I’m on the fence on with one to get is the Anycubic the better one to get or the Elegoo at one point I live in a warm climate where it barley gets cold at all and I love the new features the elegoo has for the price but on the other hand the Anycubic has more items but I didn’t want to use the Anycubic own slicer for the features like auto ydetection
My job if to report on the features and describe the pros and cons as best I can. I hope by doing this I enable people to make informed decisions about what they buy. Don't rush your decisions. Enjoy the browsing journey 😁
Will you also be reviewing the regular one?
Love the info on this, ,makes me wish I waited.. BTW, I just wanted to tell you I gat a file you did (Thingaverse) for a little DnD cotage and printed it in PLA on my old Ender 3. I did 2 of them and they both turned out great. Keep up the great work!
That's great to hear. Glad you enjoyed them 😁
I see the Anycubic Photon Mono M7 Pro is coming out. Love to see this review soon. Looks promising.
I happened to be looking for a reasonably priced resin printer when the Saturn 4 was launched so I more or less ordered one on a whim. It will replace my past-end-of-life Form 2, and it was funny to see Formlabs launch the Form 4 literally 2 days later, which is now an MSLA machine that still costs 10x as much. Anyway I will see how I go and whether I need a heater, but good to know the basic print quality should be pretty good, even if one of the first things you need to print is a handle to glue on the stupid hood.
I'm fine with the thing coming without a heating function. Anyone who cares about their health should always have a ventilated enclosure for their resin printer(s), and these are easily heated using cheaper and better options than one of those heater units. Every printer on the market which has an in-built heater is also very expensive, though (and this one would have been too), and to me personally, it's not worth the money. You can get an app-controled thermostat plug and some kind of heating system (heater lamps, ceramic heater etc) for the same money, and you can set and monitor temps from the coach.
Also, the vat tipping mechanism has some very solid fundamental principles behind it, so people will figure out to get the most out of it. I'm convinced it's going to be the most important speed innovation of this generation.
While I don’t intend to replace my Saturn 2 til it fails, in a way I don’t want to have to try to fix (I’m clumsy and a little worried about if I’d mess up wiring and such), definitely paying a lot of attention to printers coming out now since I suspect one of them will be the replacement I end up with (hopefully in over a year at least) and it’s good to see some sensible and quality of live improvements
I always encourage folks to keep what's working. Don't update unless you really need to or really want to.
@@vogman yep, feels like it’s working just fine atm so not planning a replacement or upgrade, but keep a reasonably close eye on what’s coming out just in case.
The printer is incredible, but the loss in the printing area was huge, unfortunately it won't work for me, because I print a lot of full-size heads on the Saturn 3 Ultra.
Was waiting on your review to make my decision. I'll just wait a bit longer to see how they fix some of the software issues. The thing rhat really sold me was speed and the tilt release, but seeing that it isn't that fast is disappointing
It's an impressive feature, but I cannot see how it can increase speed in any way.
Some new features, some missing features…given a choice between the 3 Ultra and 4 Ultra, I would take the 3 Ultra.
However, given the choice between the Saturn 3 Ultra and the Mars 4 Ultra, I went with the Mars for the square screen pixels (18x18 microns) over the rectangular (19x24 microns) of the Saturn. It’s been a little over 3 months and so far I’m very glad I did!!
I love the Mars 4 Ultra... good choice 😁
Nice review again. My concern is that when there are more moving parts, the chance of a mechanical failure is more likely ... waiting to hear if any reports of the tilt mechanism failing after x number of hours, probably unlikely but who knows.
Yes, many are saying the same. It's only after a few months of use that we'll find out for sure.
the tilt mechanism would be amazing to have on the next gen large format resin printer! Please Anycubic and Elegoo make this happen. I am missing so many features on my m3 maxs. Also please include propper vat handles and deeper vats. heater is also a must!
Thanks for sharing your thoughts 😁
I’m blown away we are still getting printers without heaters in 2024.
That rules it out for me immediately.
It’s the most important feature for a 3D printer.
You can get the heater for 50 bucks as add on. With the printer price ridiculously low it will not break the bank.
I think the force/strain sensing is more important if it can prevent the screen from being destroyed by debris, but in integrated heater is an absolute no-brainer.
I'm biased on this subject, I know, but there are a lot of folks replying "I don't need a heater - I don't care."
To those I would remind you, it's not about heating a chamber, it's about maintaining a constant warm environment.
My buddy lives in Australia - very warm climate. But in the evening the temperatures drop dramatically. A heater has helped his prints considerably. During the day it doesn't even come on, but when the temperatures drop, the prints stay cosey.
I know "Australia" isn't the whole world and things vary all over, but I guarantee if you look through these comments, you'll find more pro heater than con heater. And many of those, like my Oz buddy, live in warm climates, but they've discovered the benefits of a consistent warm temperature. That's why I have to agree, Elegoo need to be like Anycubic, Phrozen, Information, Peopoly and so many others that are thinking seriously about temperature control.
@@vogman Agreed. I'm in Ireland, my garage is often less than 4 degrees in autumn, lower in winter. I bought the chitu heater for my Mars 4 DLP, and I love it.
It keeps the enclosure at a constant 30 degrees, resin stays runny, and I get like a 99% success rate on my prints.
@@vogman Their temperature solutions aren't really any different than Elegoo's 50 dollar add on. A vat heater is the ideal way to do it but it's only on more expensive printers right now.
That's cool, the features you seem most worried about it lacking (heater, filter) are ones that don't matter for my setup as they are solved by my printer "enclosure".
There you go. Then I've done my job. That's all I worry about 😁😁😁
@@vogman That's why I watch your videos, no fear of being critical and you just lay out any potential issues clearly.
I have my resin printers in an old commercial bench fridge which is heated and vents outside, so I smell nothing when the doors are closed and can easily control the temperature.
I'm over here still rocking the 13 series 1 Saturns. lol
If it's working for you, that's all that matters 😁
What are the pros and cons of making a comparison between Phrozen revo and saturn 4 ultra.
They're similar spec, but the Phrozen feels more correctly put together, as it should for the price. But you can buy 2.5 S4 ultras for the same money. It needs plenty of thought.
I'm curious, there is a big difference in price between Phrozen and Saturn 4 Ultra. Is the price difference worth buying Phrozen?
@@vogman Unfortunately, when I pre-ordered the Revo, there was no news about the Saturn 4 Ultra and suddenly the news came out and the distribution of the product started and I was shocked. I've seen the reviews. I really like the reviews of your channel and you also provide detailed information. That's why I care about your opinions. As you said, there doesn't seem to be much difference and there is actually a big difference in price. I'm still confused. I usually think about printing figures. I look at figures printed with Phrozen and people who work with figures. Their work is really nice. When I look at the works printed with other printers, I see that there is a difference in quality. Of course, this is entirely my opinion, and it may seem wrong to me. Or there is very little difference and that difference is too much in terms of price and I'm not sure if it will work for me :D
@@ozkanmemisoglu9085 I wondered the same. How is the Revo jutstified for the price of both printers basically have the same features?
@@ozkanmemisoglu9085 I can tell you that I have a Phrozen Mini 8K and a Mega 8K and they work perfectly, I recomanded the Elegoo Mars 4 Ultra to a friend and it was dead after 3 prints. I will buy a Revo on Black Friday or Cyber Monday.
I have the elegoo saturn 2 and considered upgrading to 4. However I think looking at it now I can get a few more years out of the Saturn 2.
If it ain't broke, don't fix it 😁😁😁
Vog man, there is a chance you expirience with the 4 cones being off might not be the printer... The cones v1 is only supposed to be used in the middle of the fep, and printed alone, as printing elsewhere can affect how the cones behave due to uneven fep pull forces. The cones V2 and now V3 avaliable on the table flip foundry discord have walls around the cones so this shouldn't be an issue. The cones v3 also has a dimensional accuracy test which I worked on, it's in beta on the discord server as that is being refined.
In fairness I did other tests than the cones... I just thought the cones were easier to demonstrate 😁
do you have the Seryatech cast blue or purple settings for the elegoo mars 4 9k…. if you do please share that information I’ll totally donate to your channel and or subscribe to your Patreon. Because I know I’m not the only one I can share that information with the thousands of people on the Facebook groups that are having the same problem.🤦♂️
Is the vat actually innovative, given that the Form 1 and 1+ had a tilting vat years ago, as did the Prusa SL1 and Prusa SL1S. Now maybe Elegoo have done a better job than Formlabs, who I believe didn't have a tilting vat in their subsequent models, but I think we need to see how it pans out with this model. I honestly struggle to see where there's any innovation with this model personally. Like many of us, I'd like a heated vat so we don't need to use brew belts, automatic filling, level sensor, vat temperature monitoring with a contactless low res thermal camera or other sensors, replacing the -shitu- chitu firmware for something decent and thus a better print experience (Bambu show how much better it can be having custom firmware over what others are doing), and a slicer that can leverage said better firmware. Providing something like Fujifilm Prescale might be useful too for validating actual bed levelling (as opposed to Z height), but Prescale is super expensive. Heygears seems sort of like the Bambu of SLA, with a somewhat integrated system that's an improvement in the experience, but I don't think we're seeing anything particularly exciting anywhere. Wondering if Bambu are looking to take a lead in this space too; certainly hope so!
I wonder how does this compares to the Elegoo Mars 4 DLP?
Depends on what you're looking for really. Try this www.vegoilguy.co.uk/3d-resin-printing-which-printer.php
I'm looking to upgrade from my Mars 2 Pro to something bigger and newer but still not 100% sure... The price is really good though!

5.5s a layer is faster than what I usually get out of my Saturn 3, which is 7.5s. So if the layer time is actually 5.5s that will save a bunch of time. Obviously not 150mm an hour though.
There's no reason it can't be 5.5s considering exposure is about 2. Should have shown the math in the review which makes 150mm/hr basically impossible unless doing .15 layer heights or something crazy at which point might as well use FDM, silly marketing
Me personally, I'm fine it comes without heating (but ofc it's a downer for those who need it). I'm not interested in timelapses neither, but the cam is a nice to have feature. If the *cough* "AI functions work...or just few, fine. WiFi should be standard on ALL machines >200$ in 2024.
There are only two things that I'm really worried about: That build plate design makes it difficult to clean/drain I guess, not even speaking of the possibility of resin creeping into the chamber of the screws/springs. And the tilt mechanism ofc. First model with this new tech (at least for Elegoo)...thousands and thousands of movements all the time. We will see, if they nail it with the first attempt or if there will be issues...if it likely fails or tear got impact on its accuracy. Or just imagine resin dripping into that mechanism. The drip tray looks flimsy as well, no wonder people confuse it with packaging material. It would be nice, if you could turn tilting off, when you don't need the extra speed. At least that way, you could reduce the tear. But afaik it's active all the time.
I'm fine it comes without a handle, it's easy to attach a DIY solution or printed one. I ordered the S4U as my first resin printer, just hoping it works out well (at least my Neptune 4 from Elegoo works flawless out of the box for 800h so far) I don't print much with resin so I won't stress the mechanical parts 24/7...I had good experiences with the customer support so far, so I'm not worried when it comes to possible issues. Some features need improvement, but I guess we will see that with the next generation(s). This seems more like trying to catch up with features at a small price.
Btw that CEO from Lychee released a "not only hype" video as well...auto translation got some issues with French, but it's a good watch as well. Thanks for this video, I really like those that don't hype products straight away, 've seen too many presale pitches already...this one shows both sides, the good and bad. The customers can decide themselves, what is important for them and what they can do without. And in the end, long term user experiences will show us, how good that printer really is. Sry for the long text...hoping for the best, thanks and greetings!
I have the impression that big huge prints of things that have to be straight, directly on the print bed, like a mold for a vase, a cup, etc... would print better with the method the fep sheet releases itself. Maybe we can print straight 90 degrees items better now....
Interesting thought.
according the the elegoo website the saturn ultra 3 to has a Build Volume of 218.88×122.88×260 mm³ and the new saturn 4 ultra 218.88 x 122.88 x 220 mm³ which means the new saturn 4 ultra has a smaller build volume. might of been worth a mention.
You're 100% correct. Unfortunately this video was getting epically long and I've had to shave parts off just to get it done.
I do mention the print volume though, and include "Chapters" in the description to help folks find this stuff 😁
For me is better the heater is optional, I live in a hot country in latin America, I'm glad that i dont have to pay for something i will never use. For the other things I Agree with you.
I'm torn between this and the DLP. Been wanting a resin printer for ages now. Phrozen is another option, choosing is overwhelming lol
You've just got to decide what features you really need. Maybe this will help a little www.vegoilguy.co.uk/3d-resin-printing-which-printer.php
Good, quick review with nice sharp closeups of samples as we’ve come to expect, thank you for that!
One of the sticking points of the review kind of bothers me. You make a stink about a cheap 30¢ plastic tray which is pretty much necessary, and another about not including a $50 heater, which presumedly we’d be forced to pay extra for.
Why should people in tropical or temperate climates be made to pay for something that they would never need? It being an OPTION is the correct way to go for something like a heater.
Also, I can buy the same type of mini heater for $35 through other outlets.
I’ll definitely be printing a very low profile, style appropriate tab for the lid though. Definitely a design oversight on Elegoo’s part.
My job isn't to do anything more than inform. I speak honestly and try to be balanced.... I like this because... I don't like that because...
When I see a flip top lid with no handle, my personal thoughts are "This company had no idea WHY it was fitting this type of lid." The benefit is one-handed convenience. Without that, there's no benefit.
I know plenty of folks that live in warm climates but have suffered printing problems through temperature drops (for example, a pal in Australia tell me how cold in gets in the evenings). Heaters aren't just about making a warm environment, they are about consistency of temperature, and that's where prints work best.
As for the tray, I bet Elegoo wished it cost 30c. The money they probably spent on R&D would no doubt set me up for life. And this was for something no one has requested. A heater though.... so many requests for those.
Ultimately I'm just saying what I feel. I don't expect anyone to blindly agree or disagree with me. Instead they need to gather the facts and make up their own minds. I hope I help a little in that regard. 😁
Is there a way to print without the tilting? I'm interested in all the features *except* for the tilt release.
Buy the Saturn 4 all the futures without the tilt release and cheaper.
You should take a look at the non ultra Saturn 4
Not that I've seen, though I agree that would be a useful feature to add - just in case.
Nice idea with the wobling bed. Bad execution on the printer. Thats gonna be a pass from me.
Sounds like Elegoo finally realized Prusa did the tilt years ago. Seems like this is a bigger built plate though. #LLVM
Spot on 😁
I'll stick with my anycubic.
Coolcool
The most even-handed review I've seen so far. Every other Saturn 4 Ultra review I've seen has come off like a paid ad. I suspect there are a number of things people who received review units were asked not to talk about. Like, you've mentioned the similarity to the GK 2, but I think, at least visually, Elegoo were taking notes on Heygears' Reflex. Totally different machine, but it looks a little Heygearsey to me.
Tilt release is something I think the Prusa resin machine had a few years ago, so I'm surprised it's taken this long to make it to the cheap Chinese machines. It should certainly improve print speeds and reduce failures, but I do worry that it might add a point of failure for the printer itself. Part of what makes resin printers so great is there's nothing to them. One motor, a threaded rod, a plate, a screen, a UV light, and a vat. The rest is all window dressing. Adding another motor to the mix, which can have variable performance, worries me a little.
As for auto leveling, I'm not sure that's something we really need is it? I've leveled the bed on my Anycubic twice in a year and a half, and I don't even think I needed to the second time. Resin printers are easy to level, and they maintain that level well. It's a godsend on FDM machines, those fiddly bastards will frequently vibrate themselves out of level, but resin printers are much more stable.
That's because a lot of them are paid ads 😁😁😁
I'll stay honest and balanced, even though I confess it would be nice to pay a fill bills 🤪
@@vogman The strangest thing, and I asked Elegoo about it, despite there being an exhaust port on the back of the build chamber, the only thing Elegoo sells to hook up to that is the "Mate" air filter. All I'd want is a hose with a fan, and a window kit like those portable air conditioners.
There is, charitably speaking, _mixed_ evidence VOCs are actually reduced to safe levels by charcoal filters, so when I run my printer I've got a couple of filters running inside it, and a couple of bigger, room-scale ones doing the whole room, but I still put a big fan blasting out the window, and wear a respirator in there.
Thanks for this onest review.
In an era of wannabe experts shilling their soul to the first company that sends them something for free, having someone review the actual product, with his flaws and all, it's like a breath of fresh air.
Unfortunately a lot of those shillers get more views than me. The worry is eventually I'll be side-stepped in favour of those pretending to be honest and getting the views. In the meantime, if I can help people make informed decisions, so much the better.
Odd you call Elegoo Stupid for no handle but state you love the Uniformation GK2 lid and state it will be Resin Free from handling when it has no handle ?
The GK2 does have a handle. What makes you say it hasn't?
@@vogman It really has more of a lip (Which you did say) that is part of the lid. Not a "Handle" in the sense he might be thinking. But you would be touching the "Lid" with the lip. I added true handles to my Saturn 2 by printing them on the Bambu X1C and double sided taped them to the said - Will probably do the same to the 4 Ultra is I end up with one.
A simple and effective idea Prusa has been doing for years
And Formlabs too I hear.
And overcharging for copied crap for years, too.
$2000 for a tiny little 2K printer (0.05 mm pixel size, 127mm x 80mm x 150mm build size), with obsolete misengineered "UV LED Matrix" (just like an OG Photon Mono]) yeah, right 🤣🤣🤣
Having an advertised print speed that cant be obtained even remotely close has to be some form of blatant false advertising. As somone whohas the Saturn 3 Ultra and cant get it to update its own firmware, and now this, I think I'm done with Elegoo.
At least this one does update its firmware... for now.
The biggest difference between this and the saturn 3 is that it has 2x the ram which should hopefully vastly reduce the chance of the screen glitching during big prints using AA which has wasted countless vats of resin of saturn 3 owners. Elegoo won't tell you about this because they still haven't acknowledged the issue with the saturn 3 despite now releasing a new printer with 2x the ram which should fix the issue, now why would they do that if they don't know that there was an issue??!
Interesting. I hadn't heard of that one.
But I'll remind you... the Mars 3 I tested had a wobble on the Z Arm. Elegoo denied. Just about every CZcamsr denied it. Consumers moaned about it.
Elegoo changed the Z Arm... but there wasn't a problem 😏
@@vogman yeha I've been sending tests to J3d who has been trying to get this issue through to them since at least january, but communication to the chinease engineers is slow and can be confusing aparantly. It took 4 months just to hear back that they don't care about lychee tests, only chitu, so I now tested chitu and AA is fine but image blur 2 or 4 is equal to lychee smooth surface 2px or 4px in severity of this issue, so we will see what they say now. I was hoping that this could be fixed from software but from talking to Julien one of the lychee devs, the UV tools dev, and Jan, it seems like hard ware limitations like the ram may not be significantly improved with better code or making non RLE compressed formats like CWS avaliable. Perhaps they could try 4 bit like anycubic, but I'm not sure if that would work. The issue seems to be something to do with if there are too many pixel changes on a few lines (usually due to grey values from AA) the RLE compression can't compress enough, so when decompressing the system just can't do it and so after those lines it just buggs out
Let's see how long the tilt mechanic will last.
Time will tell 😁
Finally a honest review and not just a marketing campaign.
Even at that price I gonna buy a Saturn 3 Ultra used and wait to see what they do in the Saturn V Ultra Plus RePlus.
My opinion.
That claim off 150mm/h maybe can be real with a 0.2 layer height.
Now Elegoo say that the cob fresnel its the best but they drop that in the S3 Ultra for the COB+Refractive Light Source that its the same light source that Phrozen Sonic Mighty Revo 14k use.
That tilt mechanism its a old technology from 2012 that company's like Formlabs used in the Form 1 and drop in the Form 2. My bet its that Eleggo gonna drop that tilt vat in the next Saturn 5.
Thanks for the kind words 😁
Great review. Its nice to see an *actually honest* review. It seems like this and the M5s Pro are pretty much neck to neck in price and features, with a little give and take here and there. I think anyone who owns either machine is going to absolutely love it. Can you really not manually level the bed though? Maybe its just an unusual process documented elsewhere or something, sort of like Bambu?
Why the hell would you even attempt that? The point is not to screw with it.
Considering my prints would always stick to the damn screen, I would say the tilt feature is a must from now on. ALL printers should use something like it or they're total garbage in my eyes that I would never trust.
If your prints are stuck to the FEP, the problem probably lies in the base layers. Assuming your plate is nice and level, increase base layer times and half the base lift speed 😁
@@vogman The problem lies in I got one of the first resin 3d printers made for consumers. The first Anycubic Photon which is a piece. You won't convince me otherwise. I got maybe 3 of my prints to ever work and I tried dozens and dozens.
I've not watched for a bit VOG, sorry... Life has got in the way. You are as great as ever.
The important thing is to ignore life and watch my videos 🤣😂🤣
No worries buddy. I get how it is. I very nearly didn't get this video done as things have been hectic at home.
I hope all is good with you now.
2:38 Stylus? Never heard of it...
What? You mean like the one I used in the video...?
@@vogman I mean that if you're having trouble with a small screen, a stylus can always help
At $400 no heater isnt a big deal when you can add one if you need it for relatively cheap. I live in Georgia and its plenty warm enough im my printers room year round. And the no handle on the lid can be solved by super glue and printing a handle. We are a 3d printing community arnt we?
to achieve 150mm/s you need layer height of 0.100 not 0.050
You could be right, but that's not the profile they provided 😁
@@vogman yeah they don't provide fast profiles it's damaging to quality, try 0.075, I was blown away by the quality and the speed increase was fantastic, but the speed really is just a gimic it's detrament to quality.
