Fantastic review. You all are killing it with your videos! Keep up the amazing work!
Thanks uncle Jessy!
The elephants foot is common among all resin printers, and is caused mostly by the increased exposure of first layers. This can be reduced, or even avoided by using a very long wait before print/wait after retract and lower burn in layer times. Though this is only really acceptable if you can set bottom exposure wait before print/after retract values separately from normal layers, otherwise you will be massively increasing print times, because you need wait times of 20-40 seconds for the best results.
The elephants foot is caused by resin still moving when the exposure occurs. As it starts to cure, it's still being pushed out from between the plate and screen, and the result is cured resin moving out from the masked area.
Saturn 4 ultra is clearly the first of a new type of resin printers that make it far less tinkering then it used to be. Just like moving from a stock ender 3 to a K1 things go from tinkering to printing with ease. I doubt ill get this generation but the next few years resin printers will get some amazing advancements it might be time to upgrade.
I was thinking the same thing. I still have my Creality Halot-One and a EPAX 4k clone from years back. I don't use them much though, mostly print FDM on a Creality K1. It will be interesting to see what the coming years hold for resin, and FDM printing.
I'm hoping Bambu Lab will release a resin printer to give the resin side of the industry the same kick up the ass.
Elegoo and Anycubic are getting there though.
Fliptop lid, heater, auto calibration and lauto-level need to be essential features
@@samhillier4427 vamos, que Bamboo copie a otros fabricantes para que los hooligans de la marca se emocionen pensando que han descubierto la pólvora. Es una marca normal más que cada vez que se tira un pedo, su legión de fanáticos dice Amén. Patético.
Best resin printer review I have seen so far, very infomative, no nonsense and professional, many thanks!
Aurora, I must strongly recommend Simple Green for resin printing cleaning. Everyone I know that does warhammer and miniature prints swears by it! It can be reused almost infinitely unlike 99% IPA.
Hmm the compression of the first few layers is a significant problem especially for those of us who print directly on the build plate. Kudos for highlighting this. You are the only reviewer who did. 🤔
Great review, as always! I was excited to see this next generation MSLA printer and was happy to see this positive review. This looks like a good candidate for a small print farm. Now if only a manufacturer could make an integrated system that ejects the parts from the build plate, cleans, dries and post cures them automagically. MSLA has too much messy slopping around with chemicals. A structural resin that uses soapy water would be a huge boon to MSLA printing.
Best reviews in CZcams! Nice job!
Been looking at the Saturn 3 Ultra for awhile, and now that this dropped I’m glad I waited. Time for a new printer. Great review as usual.
Another thorough and excellent review. Thanks!
Well Aurora, yet another great printer review, the Saturn 4 Ultra ticks all my boxes, UNFORTUNATELY, so did your previous review of the Sovol SV08 (WHICH YOU made me BUY) so I guess I need to save up some more Samolians before I can buy this one! Thank you (and you brother), again, for a great printer review.
This is great, one step closer to a multi-tray resin printer for multi-color resin-prints
Thorough and deep as always. Thanks Aurora. Also, thanks for sharing your settings in Chitubox.
I’m blown away by this machine. The Chinese are really starting to impress with their tech. I just bought a 50cc 2 stroke motor off of Amazon for €60, how do they do it! Very tempted to buy this machine as I’m sick of failed prints on my old AnyCubic
Awesome video! Best Saturn 4 Ultra review on CZcams!
Aurora strikes back 💪
Great video, You sold me on this printer.
Fantastic review
Great review, seems to be a good printer
Nice review thank you for your time and work. It would of been nice if Elegoo incorporated a heating system within the printer along with filtering the VOC's. For those with limited real estate the cover lifting back is appreciated however the cover requires additional space behind the printer itself in order to be out of the way. Maybe Elegoo can look into modifying this printer in it's next evolution stage.
So would you say this it the “Bambu printer” momentum for resin printers meaning it has increased speed and accuracy right out of the boxes compared to traditional resin printers? I feel like it. I stick with Bambu printers but I do have a resin printer but haven’t used it a lot because all the extra stuff you have to do to print it but this may bring me back to using resin printers again. Just got to sell my old one first.
I was curious as to what you would find as a con on this printer. I was about to tell you that you don't always have to have cons but I must say that I honestly value the cons that you have found and they are truly relavent. You are just better every day. As a fan of resin printing can you please forward to Elegoo to make a 15 or 17 in size printer. I bought the phrozen mega for 2700$ and it's was a total waste I would definitely buy this printer in a bigger size. As always great job. You are simply fantastic. ❤
Do you plan on reviewing the new anycubic photon mono M7 pro?
would you guys be getting a new camera, i think the better quality will help a lot.
Nice review. I would like to see a review on a EMCO comcept 55 cnc. It's more complex than any cnc I've seen on the channel so far but for it's size and price point I think it's a good cnc to do a review on. Thanks!
Great video as always, does the printer support a low resin (resin run out) feature when printing? I've seen this feature before but can't remember which resin printer I saw it on.
Yes, the Saturn 4 Ultra supports resin leveling monitoring.
When will this be available on Amazon?
Pretty cool innovations for resin. Are you planning on testing kobra 3?
Yes, scheduled in July.
Love your reviews !! What water washable resin do you use? How do those prints hold up to moderate heat, like sitting in a vehicle in summer time?
She said Creality.
13:04 Quick question 😄 For this scenario, will the tiled vat motion benefit if I position the model horizontally instead of 45°?
Usually, prints will fail if the first layer after support is flat like that.
Anyhow, great review!
Is there any chance you are testing the Micronics SLS printer?😆
I believe so. No matter how you orient the model, it still has to contact the film of the tray, so the tilted motion should still be beneficial for release.
I know you must be very busy but I was wondering. I know you prefer water washable resins, have you compared different water washable resins? I know a while ago, CZcamsrs stated that the level of detail with WW resins are lower than standard resins. Or they are much more brittle. What are your experiences with them, if I may ask. Thank you for your videos, I find them extremely informative and very well executed.
Great that it has a camera. One question though, is the interior of the machine illuminated? BTW one of the cons of this printer certainly is the two layer build plate - must be a nightmare to clean it between the plates :(
No, it's not illuminated. I simply wipe it with IPA and a paper towel and don't clean it completely every time when switching resin; I just let a tiny bit of resin mix with the new one.
I presume it allows you to put a lot more resin in the vat.
👍🏻👍🏻
Using water in these types of wash and cures is generally not recommended as the bearings in the impeller will rust over time. Some people replace the bearing with ceramic ones to use the units with water instead of IPA.
Screw the lacking air filter, nobody needs those as they fill up immediately, but the printer lacks a heater! That's a total bummer! For viscous resins, this makes process reliability poor as the resin heats up only during printing and also decreases print quality due to resin being too sticky.
the resin heats up only during printing?? - use a heatgun (some use hairdryer) and steer the resin, print quality is back in action
The Anycubic M7 has a heater and auto resin refill so a hard choice between the two.
I also use cooking chopsticks! you can buy aluminum ones these days!
Informative review.. i just realised they shaved 3cm off the max build height with this new version. Quite disappointing
chopsticks, the secret weapon to resin prints and cooking pasta
Hi! You keep repeating preference on water washable resin... You may wish to try Sunlu detergent that turns every resin water washable! No need for IPA any more :) I tried it with Anycubic ABS Like + resin. Works like a charm!
Oh... sorry... I wrote too early... I see you know about Sunlu detergent... :)
You can't tell the difference between the 12k and 14k, because they have the same pixel size.
👍
One more cool thing is u can use this on lychee slicer
12:38 This, I think, confirms my assumption that there is no such thing as an auto bed leveling, but just a spring-loaded bed. I have never had issues with bed leveling, and if I had, I'd just increase the bottom exposure to fill the gap. So no advantage at all, but at the cost of a massively more annoying cleaning procedure.
The tilting mechanism may be a good thing, but it comes with its drawbacks, too. On the Prusa machine, I've seen feature requests to disable it as it introduces warping.
All in all, I think this is a downgrade from the saturn 3, although I was very excited at first sight. Maybe the tilting mechanism is really worth it, time will tell, and the hood is - well - all printers will need to change to this now... But the build plate is a deal-breaker for me.
The leveling uses strain gauges for leveling, springs would not work. A BIG plus with this is residue detection, to save you puncturing FEP.
@@petercallison5765 Yes, agree, this sensing may be a life saver. But these sensors are not likely to be in the buld platform, are they? I don't see any communication measures like spring contacts. And I'm sure there is no wireless communication. So it's just one single force sensor. And even if there were several sensors on the plate, auto leveling to me would mean that there are motors in each corner of the plate, which would twist the plate accordingly. So on the plate itself it's just springs, isn't it? If you push the plate on a corner, will it retent and then spring back? Sorry for asking again.
Hi! nice video, I just have a strong doubt about how well that autolevel system works...
Anycubic's M5s used a similar system and it was total rubbish. the build plate was crushed against the LCD and the prints were severely deformed in height.
Could you try printing 5 2mm thick discs (4 corner and center) and measure with a caliper how thick they are printed?
Aaaannnndddd…. I just bought another printer. 😉
Me: Oh that piece came out crooked. Oh wait, that’s the Leaning Tower of Pisa.
6:54 Huh, that's not right -- that tower thingy got printed at a bit of an angle! Oh wait....
The loss of available Z height over the Saturn 3 kills it for me.
none stick working mine never do
The review I've never seen: of truly safe resin. Few realize how toxic current resins are.
or you can use Lychee
change your processor...
If this printer had a cabin heater and a resin pump, I would get it.
Also one problem I find is, I think air filters are mostly worthless and a air hose is always a better solution. But I am scared of sucking too much air, fast enough the ambient temperature inside decreases rapidly, to cause a print failiure.
So a machine with a controlled fan right before the hose exit, would also be a wonderful addition.
The Anycubic M7 has both of those.
@@petercallison5765 I didnt know, I will take a look at it thanks a lot for the suggestion
I wish this wasn’t a paid review :/
Tons of new features? List of them is 0 😅 like what's new? And still they make this printer half good... Like why? In my opinion the only full and good so far is GK2, that printer should be a start point and from this one they should upgrade things, this printer is lacking of hinge to lift up cover xD Elegoo rly...
Tilt tray, residue detection and camera and it has a hinge, what is your problem?
@@petercallison5765 it's nothing new 😅
Wow that’s cheap
If their fdm printets are mediocer at best, at lest they are doing better in the resin department. At lest till Bambulab comes out with resin and breaks the market again 😂
Ugh another Bambu fanboy. You do realise elegoo have been at this a long time?
You guys are as bad as apple shills
they not going to come out anything similar just because there is nothing to collect(loot) from the open source community
@@tjCooper88Bambu fanboi here. They dont need to make a resin printer, Elegoo makes amazing printers and have the best customer service.
Its alllllll from china.
@@mendicantbias5211 as a reseller of Elegoo brand i can tell your in big dream.
I'm not sold on this printer...bed levelling has never been a problem for me, so auto-leveling doesn't mean much...my two main conerns are (1) there are now two major moving systems on the machine (build plate and vat), this means there is more chance of components breaking down or working their way out of tolerance/calibration over time, and (2), almost always I like to wash my prints whilst still attached to the build plate, this build plate seems to preclude that possibility.
The build plate detaches with the flip of a lever
@@SolarAbyss Not sure why you said this...
@@mackbolan1733 Why do believe the build plate precludes washing the prints while they are still attached?
i have 3 resin printers and cannot really remember when I last leveled them, auto-bed leveling is a marketing buzzword. if I remember right formlab had this vat tilting system and they dropped the idea (I guess for a good reason) btw never rush to buy a new system lets wait till other ppl beta testing it lets see how it goes after a year
@@xeraoh 100% agree...
