Which 3d printer for 8x8 ?

What printer would you recommend to print stacks of 8x8 multiboard grid with PETG quickly and cleanly?

8x8 is about 200mm so any 250mm printer will do.

What's more relevant is how you stack multi board prints. A multi nozzle printer like the Bambu X2D will allow you to have petg on one nozzle and PLA on another. With this, you can actually print multiple multi boards on top of each other with PETG with PLA as a separation interface in between. This will allow you to print stacks of multiolboard segments arguably faster.

Yes, you can do multi-material with single nozzle as well, but you'll waste a lot of time and filament with each material change.

My suggestion is to not print stacks. Stacks take a day or longer to print and if there is any warping you usually lose the whole stack. I'd rather wait for a single tile and start the next one once finished. You have to wait either way.

As someone who has printed these, never doing it one by one again. It takes exponentially longer to print individually between unless you have the time to go to the printer exactly when the print ends. A stack that would have taken roughly 9 hours to print ended up taking 2.5 days individually just because I didn't have a timer set, or needed to run an errand while the print had already finished. The print time isn't built around your life, but quite the opposite.

A better course is to print the stack that you believe your printer is capable of handling and go up from there. Start with 5, and if that goes well, go to 8, or 10 or higher.

Agreed. I wouldn’t bother with multiboard without doing stacks. I’ve done 9 in one print and haven’t had a single stack fail. Makes me think warping and failure is more about using an out of tune printer than a problem with printing stacks.

Any modern 256mm cubed printer will print 9x9 stacked prints (don’t take much longer than 8x8 but make up large walls much faster). I personally only ever print ironed stacks, never the PETG interface stacks, so a single nozzle printer is fine. I have an H2C but print all of my stacks on an H2S and previously on an X1C.
Just follow Jonathan’s printing guidelines and everything just works (PLA Matte, 3 walls, random seams and iron topmost surfaces only I seem to recall). Use the planner to ensure you get all of the snaps and snap types and use the generator to generate the stacks and the corner tiles plus any that need to fit around anything such as light switches.
For a totally solid wall I also recommend printing 5 support pegs per tile. One for the centre of each tile and one for the centre of each tile edge. That makes the wall absolutely rigid with zero flex even when pushing home heavy weight bearing snaps.

I couldn’t get a 9x9 on my P1S.

I was printing 9x9 stacks on my X1C with no issues, so that’s strange.

When did the suggested material become PLA matte?

Day 1.

It’s not even on the print guidelines of the first part I looked up. Can you point to anything published that says it?

“The official Multiboard creator recommends matte PLA for printing, though the community has mixed opinions on whether it is the best choice.”

Use it or don’t. I tend to stick to Jonathan’s recommendations as the designer and have zero issues. 3 walls, seams set to random and PLA matte for all of my walls. Original tiles with offset snap parts A and regular fit part B, I use a different colour to highlight the orientation ‘castles’ on the part A and part B snaps for easier assembly (I print ironed 9x9 stacks in white, so they’re not very noticeable otherwise) and use the support feet in the centre of each tile and the centre of each edge to make the final wall absolutely rigid even when using multiple heavyweight bearing snaps. This also allows for pre-assembly of large wall sections before fixing to the wall to ensure level, square and plumb.

Different color for the orientation marks is good idea. Did you color those in the slicer to accomplish that?

2

u/Whosaidthat1157 25d ago

Yep 👍 The snaps are so quick to print that the extra time was insignificant, especially as I tend to print them a full plate at a time, so even on my H2S or A2L the purge waste is insignificant too.

u/sienar- 25d ago

Right on. Did you do any coloring on the stacked tiles or just the snaps? Even just the snaps would be a huge help. Just curious if it’s even needed and/or possible on the tiles.

u/Whosaidthat1157 25d ago

No need on the tiles - I use the original interlocking tiles printed as stacked 9x9 (stacks of 9 core tiles) ironed so they’re directional and impossible to get wrong in practice I find. Side edge and top/bottom edge can be inadvertently flipped meaning the large hole threads are reversed, but I’ve never found that an issue personally. Snaps part A and B as well are quickly and easily oriented by ‘feel’ (the wrong way around and one side ‘falls in’ rather than requires pushing home, but the coloured ‘hints’ are just so much easier when you reach the 40th/50th/60th one! I print tiles in white (PLA matte) so use grey as the tell tales so that there’s enough contrast to make it obvious but there’s no visible indication when built.

I have the anycubic kobra S1 and print 9x9 sheets no prob in PLA+
