Thank you for this!
Nice tip. Do you have plans to make something compatible between Multiboard and GOEWS?
For those having trouble / just cannot get the supports to show: Instead of doing the settings on "Global" use the settings for the merged "Objects". Worked for me
Thank you for this video. I had been printed stacks of these, but with the settings I was using, there was a tonne of waste from supports. But by changing my support settings to what you have, it cut my printing time in half and uses WAY less filament for support structure. I'm currently running a print and using PETG as my support material (I didn't want to use it before because of the amount of waste). I'm hoping my results are as good as yours.
Couple of failures so far... I'm hoping it's because I had ironing of top surfaces turned on that the PETG is not sticking properly to the PLA. My PLA says cold plate of 35, which is what I set the PETG to. I'm wondering if I need to change that to 45 like yours says. I'm trying another two layers... Guess I won't know until 8hrs from now. I really should have done a 4x4 and ran some tests rather than on full sized tiles. Doh!
Nice. Never thought about doing that. Great video.
Thank you sir.
That is a very neat trick. Thanks for sharing.
Man this is amazing! I have some rather simple parts that are just barely too big to fit two on one plate so I am going to try this soon! Great Video!
Awesome! Great tip.
My max is 4, the 5th one lifts... 4 is better than 1, besides I think it's good to give the printer some down time. Using the same colors I had no cleanup to do.
Thanks, been looking forever trying to figure out how to stack gridfinity using petg as a support
I've been using TPU as a first layer, PETG above that.
Nearly impossible to separate TPU from PETG.
My Vase-mode prints now have a 'bumper' on their base...non-skid and all that.
Printed on a holographic build plate, black TPU makes a near perfect copy of the embossing.
What is the product you have printed? Clever stuff
Thanks for sharing the informative video. I was wondering if this would work with other slicers and machines like PrusaSlicer?
Bambu Studio is basically PrusaSlicer. they are based on same code base. so should work fine. havent tried others.
3:08 "Ideally you would use a very thin print" instead of supports, so why not scale the z axis of a petg model down to a very thin layer between the pla? same difference?
Mine does a weird thing where one of the panels is half made with petg, and no support in between. I’m using bambu studio but I think I’m going to try with orca.
How much did you use for flushing amount? I've found that I have to max it to 800 to be sure there is no weak points from contamination.
But why don’t you print the second part just completely with petg? Then there would be nothing to throw away.
If you need to print pla I understand. If it makes no difference then you could print the parts pla, petg varied.
Oooo…great idea with zero waste! Love it! We’re new to 3D printing (we’ve got a Bambu lab) so we have a long list of things we’d like to print, so being able to stack them and leave it printing lots of matching plates in one go seems like a game changer (or an awesome efficiency hack). 🙂👍🏻💕
2 hours to do 1 mulitboard, if you do 2 with petg separating them takes 5 hours 12 minuets. So 1 hour 12 minuets extra to do 2 at a time. Didnt bother to check how long 3 stacks would take. Faster to do 1 board at time, than filament switch to keep them separated.
I just stack them 0.2mm (or whatever you normally use for you Top Z distance) and print them without a support layer and pull them apart without any issues and zero cleanup. Never had any problems with reliability
I tried that a few times too. But had more issues then success
can You only stack print with multi material?
@@GCS88 you can do it manually swap one Mayer for another. Or you can use a small gap to space out the tiles. Need to test with small model to refine your settings first
Feel like inverting the materials is the way to go.
I'm new to 3D printing, but I am surprised multiboard recommends PLA when everything ever says use PETG for structural stability
I say, use the right plastic for the right application.
There is a whole world of different plastics and blends of plastics that have their own unique properties and applications.
There are lots of videos out there that can point out the pros and cons of each polymer. As well as good applications for them.
PETG isn't really "stronger" than PLA, rather it has different qualities that suit some use cases. It is more flexible and impact resistant, but that isn't necessarily what you want for Multiboards, where PLA's stiffness is often better suited. PETG can also be more finicky for dimensional accuracy and shrinkage, which can be an issue for interconnecting parts with tight tolerances. That said, PLA can sag and deform under constant high load, especially in hot ambient temps, so if you plan to hang heavy items in a hot location, PETG might be better.
Bottom line, if you are just hanging light stuff in climate controlled space, PLA works great, and is easier and quicker to print.
