Gamechanger for light boxes! Good work 👍
This is quite possibly the most useful video that CZcams’s recommended to me in a hot minute. Thank you!
Came here to say this ^ - True story
excellent video! Thank you for helping us save time and filament.
This information is gold. Thank you for sharing!
You are welcome, I am glad it helped you!
Short and to the point. Really good video. Keep it up 💪
WOW! Fantastic video, incredibly practical and useful. Can’t wait to see more of what you put up. THANK YOU for all the time and filament you’ve saved me!
Rather than use modifiers, Prusa slicer has Lightning and Support cubic infills which basically print at 0-5% when you dont need them and then ramp up to whatever you set (20% for me) when they need to support features like the top layer.
also, for mass production, I would just design the pieces with hollow walls and solid top/bottoms and then just print at 100% infill so you never have to worry about the settings.
Great Video! Also didn't know about modifiers before - can't believe that! Well done!
Some really useful tips, especially using modifiers - not just clickbait after all 😊
It's a shame you don't explain the reasons behind unticking some options and how did you get to your line width calculations
You are right, I could have explained some things in more detail. Thank you for the feedback.
As for the linewidth, a general rule of thumb is not to go wider than around 1.5 times your nozzle width. With a 0.4 mm nozzle, that is 0.6 mm.
For this print, with 3 walls and standard settings, you get 0.42 mm + 2 x 0.45 mm = 1.32 mm.
If you use 2 walls with 0.6 mm, you get a 1.2 mm thick wall, which is nearly the same as before with 1/3 less distance traveled. Two thick lines also tend to be stronger than three thin ones, even if you have the same total wall thickness.
Everything above 0.6 mm with a 0.4 mm nozzle can lead to problems while printing. If you still want wider lines, you are probably better off using a bigger nozzle.
I hope that helps. Anything else in particular you have questions about?
@@Factorian_Designs this is really helpful additional information, thank you! And excellent video
Two settings that I also didn't give enough explanation to are:
"Ensure vertical shell thickness" and "avoid crossing walls."
These can have a significant impact on your printing time as well as quality. If enough people are interested, I will make a future video about when and how to use them correctly. I will probably showcase them on my most optimized model, which I have literally printed thousands of times.
@@Factorian_Designs as someone completely new to 3D printing it's helpful having the information split across multiple videos anyway. Only so much information I can absorb at once, going over a couple settings and explaining what they do, when to use them, pros / cons, would be perfect! My main takeaway from this video was that we can create geometries to selectively change infill, along with other settings.
Even just seeing you scale and move the geometries is helpful. I've scaled prints down a bit to fit my A1 mini, but I don't know what I'm doing, it's useful seeing someone else interact with the slicer.
@@Factorian_Designs that will be awesome
You earned a subscriber. Well done!
Im glad I came across your video. Great and useful content. Thanks
Excellent video. I'm going to try it on my next print using Orca slicer. Just subscribed to your channel. Keep up the great work.
Awesome information. Can't wait to try with my new A1. 😁
Love it! 👍
Very helpful video thank you for sharing
Subbed. Hoping you make more of these really informative videos. I appreciate it
You've packed a lot of great information into 7 minutes. Thank you!
WOW WOW WOW thank you
Would love a follow up video to explain the settings unticked. Explaining the line thickness stuff would benefit beginners also.
In SuperSlicer you can adjust top layer width separately. Also you can use height range modifiers for get similar result. Not sure if Bambu has it, but it is as SuperSlicer is based on PrusaSlicer, which have height range modifiers as far as I remember.
But adding objects with modification is also a useful way to tweak your model. I prefer leave outer border with normal width, only inner border set to 150%. SuperSlicer also have option to set external perimeter different from inner perimeter.
I do not recommend SuperSlicer though. It is under serious develpment now and have multiple bugs which are fixed one by one, but it all needs time. I tried Orca Slicer which is kinda Bambu Slicer clone, but I personaly prefer SuperSlicer. I am helping to catch bugs, and hoping it will be fixed soon. Older version is more stable and I use it, when newer version fails.
Yeah I'm similar
What version are you using for stability?
2.4.58.5 is quite alright and fast with slicing. Recently they updated 2.5.59.11 (but it have some issues under W11 and sometimes crash on slicing) I use it too, most of the time it works for me, but I use Linux, so if you are W11 user 2.5.59.11 may be not very stable for you. 2.4.58.5 is the latest of previous branch, and as far as I know it have no issues. But I may be wrong, as I did not run it under Windows. But main maintainer check his builds mainly only under Windows.
There is a nice feature like dynamic layer height. I guess Bambu should also have it. It may speed up print by using higher height on parts which does not need much detail.
@@enosunim thanks for the detailed answer, ATM I run 2.5.59.9 on my win 11 machine and haven't had any issues yet but I don't wanna jinx it by updating to 2.5.59.11
Hopefully 2.7 isn't far away, I miss tree supports from orcaslicer 🤣
@@Krautech I guess if 9 version is OK for you, you should stick with it, as 10 and 11 versions are just bugfix releases for those who have trouble mainly on Mac and Linux.
You are right, Super Slicer has some excellent settings, which will hopefully get implemented into future versions of Bambu Studio. But like you said, I had lots of bugs with Super Slicer, which at some point drove me crazy.
Orca Slicer / Bambu Studio currently has the best overall performance for me.
you know the video is good when the intro is a powerpoint
Great video! I switched my A1 to the 0.6 nozzle but haven't experimented with many other settings to speed things up like this, since it should technically have the capability to but it doesnt seem like its helped all that much. Curious about your advice on that. Could be a video idea as well :). Subscribed!
This works with any nozzle size and printer. But you probably have to increase your layerheight with bigger nozzles and higher linewidths. At some point maximum flowrate will become a problem but that is a whole other topic itself.
Other things i do, if design and flows allow me to, is higher speeds (250-300) for inner walls and infill.
One of the best mods i did for big parts on x1c is the e3d obxidian 0.6mm nozzle. I can get like 30mm cubed flow with any filament (don’t even tune it, just turn it up and send it). This with 0.4mm layer heights and printing big stuff now in like 1-2hours. Big stuff for me is workshop organisers etc. stuff I don’t care of visuals, just speed.
I love the ability with this setup to just be able to do quick test prints in less than 30 minutes sometimes for like 5-10mm z height test fit objects
could just use lightning infill, leave your outer wall thickness at default too
nice video, thx. Additionaly I use variable layer hight, this is great because detailed features get better results and less detailed stuff is printed faster due to increased layer height.
What I didn't understand is the modifier thingies. Why you choose the geometry modifiers instead of much simpler height modifiers? just add height modifier for the first 5 mm or whatever your bottom height is and then select the infill percentage, same with the top.
A note to z-hop: This is mentioned often in "make prints faster/better/... videos" For at least my printer I have to disagree, prints look terrible if I switch it of completely. So better say "try switch it of if your printer is ok with that".
Thank you for your input with the layer height, good addition.
If you use height modifier for the lower part, you get a little more infill where its not needed the modifier is a better fit.
I see no difference with z-hop on/off but this doesn't change much for the printing time anyways. :)
Why do you think z hop has no benefit? It was implemented for a reason, it greatly reduces the risk of crashes and dragging. If you experience stringing as a result you need to tune retraction settings or reduce travel.
If something curled up it will either way get hit, with or without z hopping. I have turned it on for the noise reduction.
Lost in Tech has a great video about z hop where he explains it way better than I could with text, you can checkt it out here:
czcams.com/video/4xyevbElGIU/video.html
It can have some benefits but most of the time you don't need it.
2:38
You could also just increase top and bottom layer count by a few until the bottom is solid, but the rest is hollow.
This would almost certainly correct any bridging issues on the top layer by the time it reaches the last few layers as well.
(Though, I'm not sure if the concentric pattern would cause any issues in this particular model without testing it...)
You could do that, but that would need a lot more filament :)
@@Factorian_Designs
Certainly more filament, but it may be better for certain use-cases.
For example, I prefer many of my prints to be bottom heavy.
Though, I will admit my suggestion would not be ideal if you were printing many of them.
I would probably only do this if it was a one-off print, or a small number of them.
In this case, the few grams extra would be quite negligible to myself.
I will slice a test model using both methods and update here for a comparison.
To each their own!
Would this work with articulated models well or are these suited for larger objects like the vase used
That depends on the articulated model you are printing. I would recommend playing around with a few models to get the hang of it.
I am sure articulated models can be improved to some degree as well. However, modifying your prints as shown tends to work better with symmetrical models.
as I know you don't need to draw those cylinders and so on.. in cura I have used post processing and you can set at which layer height or layer number which options you want to be set for infill or whatnot.. so its quicker and does the same job.. or maybe I misunderstood the point of video because I didn't watch it whole
No, you definitely need the lower modifier as you don't want infill in the other areas. You are right about the upper part. As always, there are multiple ways to get a job done :)
Are these settings good for any print (even models/action figures) or just for prints of vases or simpler things?
Thx
I would use them a bit different for action figures. You will probably be better off using a low wall count + lightning Infill in the general settings and then add extra walls with modifiers where your model is fragile. This should save filament and reduce printing time.
I hope that helps!
With 0 infill do the vase walls squeeze together every time you pick it up? From a quality perspective I would imagine customers might think it's low quality if so, similar to how you mentioned vase mode printing.
1,2 mm thick walls with this kind of outer shape which is also connected at the top gives a pretty sturdy structure. I haven't had any significant bending so far.
Hi, thanks for the video. I got a bit lost after 4:35. Why the upper cylinder disappears after a few seconds? What changes have you made ? How can you avoid printing the upper cylinder ? Could you please explain more? Thanks !
Hey, the cylinders I added are just modifiers. They only change the settings for the main geometry where they overlap. The modified settings for the cylinder are only the infill %, type and top layer pattern.
The shape of the modifier structures themself will never be printed.
I hope that helps!
@@Factorian_Designs Thanks for giving me the keywords! I managed to find more youtube about modifier and I now understand what it does. That's briliiant!
Why does the top modifier not add infill in center of object but bottom modifier does? Is there something i missed? Or is it because the bottom floating surface is in modifier but wouldn't that be support and not infill at that point?
Cause there's open space? The modifiers only add things to the model where its touching...
Exactly.
Support is everything that gets removed after printing. Infill stays inside your model and is there to support your top layers.
Lightning infill is my simple cure.
instead if I remove the z hop when retracted, does it bring any improvements or practically nothing?
I am honestly not sure. If you try it out I would love to hear if it made any difference.
6:14 what value for .6mm nozzle? I set it to .8mm, being carefull not to go 1.5x larger than nozzle which would be .9mm
I think thats perfect, did you try it out already?
@@Factorian_Designs printing as we speak
Nice job, but the strenght of the vase, will not be the same as before, it will be more fragile, i suppose
The missing infill barely makes a difference. Strength comes form walls, not infill and its plenty strong this way. You should try it out yourself!
The upper infill prints in the air
With a short distance between walls, I’m wondering if most printers could easily bridge that gap, but bridging changes extruder temperature which can lead to a line in the layer when using settings optimal for overhangs.
True, but a tiny bridging gap like that should not be a problem for most printers. I am not so sure about the printing temperature change for bridges; I don't think it works like that in Bambu Studio. Usually, the printer only slows down.
Sehr spannend. Hast Du auch einen deutschen Kanal?
why not use lighting?
Lighting normally doesn't result in a strong bottom layer.
1:45 it's fine turning it off, but "wears the z-rods down"? I think you'd have to print for a couple of centuries for that to happen
the only thing you did to save time was reduce the structural integrity of the part. That was always an option that is tuneable by adjusting the infill density, You've just manually selected where infill is most important. The other settings you suggested wont speed up your prints and are highly subjective to each printer. Disabling them for every print is not a solution to increasing speeds or surface finish of parts. If you tune your retraction settings properly, you wont have issues with Z-hop. The only reason that people typically do is because they've neglected to adjust these settings.
Manually selecting where infill is most important seems like a very useful tip. Cool getting to see how to do it.
@@IronHive I don't disagree, but it's not applicable for every print. The title of this video implies that you can just simply adjust these settings to cut your print time in half, when they could have just made this a tutorial about variable infill. They chose a clickbait title and only really demonstrated that they could reduce the print time of an oddly specific part
@@bugsuck11 to be clear.. from this title, you expected this video to cut all 3D print times in every circumstance in half?
How about just designing it better?? Why does it have double walls? Just make the walls 5 layers thick in the model. The same goes for the bottom - what use is the double bottom? It won't be strong with 3 bottom layers anyway. Make it 1.2mm thick and you don't need a modifier. Whenever I see a model, say a box for electronics, with double walls, I just cringe. Why design models for 3D printing when you actually design them for cutting out of wood or something??
And if you can't change the model, even better way is to reduce the internal dimensions using the slicer using either the X-Y hole compensation or X-Y contour compensation, you can achieve a similiar effect (but slicer sometimes breaks the model in places if you overdo it).
Kudos for not wasting our time, though, and still useful tips (most people don't even know how to use modifiers).
Glad to see you turned off Z-hop. My goodness... The people that defend that when they don't even understand that it is for specific applications. 🤦
Hey
Kannst Du sollche Videos auch in Deutsch machen?
Wäre interessant 😊

The only problem I see with this is that you didn't reduce print speeds when increasing line width. Unless you've tested that your hotend can keep up and the maximum volumetric flow rate is not exceeded, this could lead to problems.
In Bambu slicer you can set your max volumetric flow rate so if you print widder lines, it will compensate speed, doesn't matter if you set it at 300 or 500mm/s if it has to be 100mm/s (for example)
@@maghg2764 oh yeah I forgot about that. That essentially nullifies my initial comment then.
