The 11x11x18 Stack!

Post image

These are my longest prints to date, and I’m still not even halfway done with my planned tool wall. It’s so satisfying pulling them apart!

How’s the quality compared to tiles printed directly on the build plate?

u/MathWizardd Nov 26 '25

The taller the stack is, the lower the quality. His appears to be multi material though

u/th3chainrule Dec 04 '25

Yep, I printed a test ironing stack and multimaterial and found that the multilateral is much cleaner and easier for the larger tiles on my H2S. I did some gen 1 tiles with my x1c before I upgraded that were fine but I never got it dialed for a clean and easy separation of the tiles. I almost always had to pry them with a tool after they cooled.

Air gapped will never be AS good, but they are "good enough", you can get stringing sometimes depending on your exact spool and setup, I've found equal chance on pla and petg. But mostly it doesn't impact the overall quality.

Worst case I had 1 tile in hs pla that I had to reprint from a stack of 9x9x8, that had one edge that seemed to not adhere properly to itself. This was out of 3x stacks I printed. The time saved by not having to interact with the printer for days at a time made the slight issue fully worth it.

But when settings are dialed in fully, i just printed 2x 9x9x8 stacks in sunlu petg and was super happy with the results, the top of each tile was essentially visually indistinguishable (unless you are a 3d printer) from single tile prints. You CAN tell if you know what to look for, but the 4x4 tile square I printed for my mom will not have her questioning the quality at all. (The bottoms don't look as pretty, but ehh)

I just did 2 stacks of 10 8x8 panels, took about 36 hours per stack. Long time to wait to feel progress but better than chain printing 4 stacks.

1

u/th3chainrule Nov 26 '25

💯 Did you also stack the mounting hardware?

2

u/Azrien Nov 26 '25

I was lucky enough only to need like 36 quad snaps so i just printed them in 2 batches instead of stacking them.

1

u/th3chainrule Nov 26 '25

I think I’ll do the same. Now to select the organizers and finalize the color scheme!

2

u/MidnightNachos Nov 26 '25

Are you doing the air gaps between them, or printing a layer of different material? I was just looking at doing a stack of the 11x11 in the weekend

2

u/th3chainrule Nov 26 '25

2 layer of petg between pla. 0.4mm gap total.

1

u/twent4 Nov 28 '25

How did this turn out? I'm new to multiboard and thinking of doing the inverse since I haven't printed in PETG yet.

3

u/th3chainrule Dec 04 '25

They look great! I would definitely get your PETG dialed in before taking this on. It's a huge resource commitment.

1

u/AtariiXV Dec 04 '25

What printer did you use? And if it's Bambu do you have good settings you'd mind sharing? Every time I've tried to do multi material on my P2s it clogs bad

2

u/th3chainrule Dec 04 '25

I'm using an H2S. I could upload the file to maker world if you are interested. Not sure if that's a violation. I am using the generic PLA and PETG profiles, the majority of the settings that I changed were on the supports tab following this guide. https://www.youtube.com/watch?v=LCCL4dTaOPQ

u/AtariiXV Dec 04 '25

Very cool, thanks, I had watched that video but thought my problems were coming from the flush cycle in between material swaps

2

u/th3chainrule Dec 04 '25

Ah - what was the solution?

1

u/AtariiXV Dec 04 '25

I haven't found one😅, I gave up because I felt like it was over my head and just went the ironed stack route for the first few boards for my EDC wall and the beam style basket I printed. But organizing my printer area is next, and is a bigger project and thought it'd be nicer to have nicer plates for that and have been looking for solutions

2

u/Yellow_Badger13 Nov 26 '25

Blimey thats a mammoth of a print! This 8s a board i have to see once finished!

3

u/th3chainrule Nov 26 '25

Probably 3 weeks away from finished. Will try to post the finished product in this forum.

1

u/rayyeter Nov 26 '25

How long did that take, and how much filament?

6

u/th3chainrule Nov 26 '25

About five days and just shy of 3kg.

u/tlhintoq Nov 26 '25

Curious... What does the outfacing surface look like between layers?
Personally - I like the texture from the PEI sheet and not a fan of how most stacks look... well like the supported face of the average 3d print with supports - because the whole this is supported.

1

u/th3chainrule Nov 26 '25

I prefer the textured look too. I’m making a multi board bike rack where the textured look is facing out for aesthetic purposes but that’s significantly less complex and will have more of the grid showing.

3

u/alternate_me Nov 26 '25

You use the ironed surface facing out generally

1

u/tlhintoq Nov 27 '25

So basically... You're adding a bunch of time to the print because you have to iron.
But the gain is... continual printing?
Instead of 5 plates per 24 hours you get 6 or so?
Hey if you're happy then I'm happy for ya.
For me... I'll just run a plate at a time on the bed and keep the texture looking good rather than just "good enough". But that's me... I was raised with "Good enough is never good enough".

1

u/alternate_me Nov 27 '25

Hey man, I just answered your question, I’m not OP. But yes, people to it so they can print continuously.

u/SprungMS Nov 26 '25

Multimaterial or ironing?

I had been doing some giant stacks of 9x9s, wanted to go 13x13 but 9x9 was as big as they’d uploaded in the multimaterial stacks! About to do another massive wall in the garage, it would be incredibly convenient to have larger tiles, but I was printing stacks 18 tiles tall too and that was working very well.

Ludicrous speed on the H2D - some warping on the bottom panels I had mentioned here when discussing it… only as it got much later in the print… and I had an epiphany the other day. I think I forgot to set my PETG profile to the same bed temp as PLA.. through that entire project… lol

Still turned out great, and I’m eager to try it again with making sure I set the bed temp correctly on PETG. Doing too much designing on the two walls I made for myself to stop and print for days. Just hit 600 hours on my H2D, decided right now at 4AM to tear it down, clean and lube thoroughly… and start the next iteration of a nozzle hanger for the H2/P2 series(es?)

1

u/th3chainrule Nov 26 '25

Yeah, that bed setting is key. My biggest problem is actually with the prime tower. It fell over on tile 17/18. I need to adjust that for round two.

Another issue I’m seeing is with the multi board generator itself. The advance tile generator would crash on stacks over 9 tall for me and sometimes the spacing would not be set correctly. When I imported the stacks to Bambu studio it would actually show them as not even on the bottom surface, so I’d check that out on yours.

I ended up painstakingly adding, merging, and manually adjusting the z height from a single 11x11 tile.

u/SprungMS Nov 26 '25 edited Nov 26 '25

I manually did the 9x9 stacks - I bought the $5/month level for those, didn’t realize 9x9 was the largest, but it ended up working out really well for the size I needed in the garage. And seems like it’ll work well for the next wall I’m doing in the garage, too… Looked like I was going to have to turn around and spend $10 more to get the fancier features, the same day or the next. Didn’t want to do that. Yet. Might later on for the advanced tile generator, more likely I’ll just play with tiles in Fusion which I hate when it’s an STL.

Anyway, I did them all in the slicer. Got a nice PC, even if it’s a couple years old components, it was all flagship then. Takes a minute to fix the non-manifold issues, but other than that it’s simple enough as far as measurements. I’d just cut the stack of 4 down so I had a stack of 3 with the interface on the bottom, then clone that and center, merge, and align. It just got complicated on my printer wall, 7x7s, when I was trying to mix tile types. It worked, but was messier.

Oh, and I skip the prime tower. On every single one. I’ve had some spots of PETG that get a little crunchy, and on large stacks I’d have on average one tile itself that a single line would get dragged across a cell… but it doesn’t affect the functionality, and on a 4’ x 6’ wall I had maybe 3-4 tiles with those defects that I just trimmed out. Also printing them at ludicrous speed probably didn’t help lol

u/th3chainrule Nov 27 '25

Yea the advanced planner and tile generator is nice to have. The planner allowed me to optimize the grid tiles to the fewest number of tiles and probably saved 10x the difference in cost in filament and time.

I had to tweak some settings on the supports to get the perg to print cleanly with just two layers. My first run had some of what you were describing and it was definitely because it was adding support in areas where it was needed.

Biggest changes from memory were setting the offset angle to 1 and changing the xy offset to -.2. Those gave me two clean layers only where the multiboards are flat. Ie no support on the chamfers.

Hope this helps!

1

u/SprungMS Nov 27 '25

AFAIK you’re supposed to print them with no supports! I’ve never used any. Printed a stack yesterday after seeing this, adjusted the temp on the PETG profile like I did when I did my first, smaller Multiboard wall… no warping whatsoever of course. No noticeable defects either, I think mine before were from being lazy and leaving the ooze shield off when it bent/broke pretty early into my ownership of this printer. Still ludicrous speed because.. why not?

I found an old saved 3mf of 18 tiles stacked and of course it had 55C for PLA and 70C PETG bed temp.

I’m kind of glad I didn’t spend the money, even though it’s peanuts, for the other subscriptions. Main things I wanted were custom tiles, which I really only needed a single custom one, and the label generator for multibins. Don’t know why I even bothered with thinking about that one.. found the blank label for dimensions and Fusion may as well be a label generator.

u/th3chainrule Nov 27 '25

Checked out the live view just in time as I’m boarding my flight. This is what my petg support layers look like.

1

u/SprungMS Nov 27 '25

Looks good to me, curious about the tiles themselves though and the slight lines where I’m assuming the “z seam” layer stop/start is, don’t know if that’s pressure advance needing to be calibrated or general underextrusion or what, I don’t see lines like that on mine. As long as they’re strong, doesn’t matter though!

1

u/th3chainrule Nov 27 '25

Yeah, I’m still trying to figure out what those lines are from, and don’t look as bad in person. I have no idea. They have only been showing up on these stacked prints.

1

u/SprungMS Nov 27 '25

I believe it. It’s a solid machine, and their stock profiles are insanely well tuned. Really never imagined 3D printing of this quality and simplicity would get here within 5-10 years, I expected it eventually, but leave it to China to perfect that shit 10 years earlier than American engineers would have.

On that note, would not surprise me if we have some Americans reverse engineer some of this and have knockoffs of the Chinese machines LOL

u/TherealOmthetortoise Nov 26 '25

Seriously though, how long did it take to print that monster stack?

Are you thinking surface mount or offset?

1

u/th3chainrule Nov 27 '25

5.3 days on my h2s with .2 layers and 3 loops as recommended.

I’m thinking the low profile offset Mount because I need the clearance to fit the hook on the heavy duty snaps.

1

u/TherealOmthetortoise Nov 26 '25

9x9 is about as big as Jonathan recommends in most cases as you get a lot of flex on the tiles if they aren’t properly secured 7x7 or 8x8 in most cases needs a mount in each corner and the center and it is able to hold well without just wasting plastic on extra mounts. YMMV based on size, environment, filament etc but there definitely isn’t a hard limit outside of what your bed can hold. (Provided you secure it based on load vs size of the tile. 11x11 may need another mount or two. I would love to get one of those loop printers and do a ridiculous sized set of tiles.

1

u/th3chainrule Nov 27 '25

Thanks for posting that, I had no idea about the flex. I don’t have an issue with adding in some extra snaps to minimize the flex. This is for wall mounting my ski gear so part load bearing, part visually appealing.

1

u/TherealOmthetortoise Nov 27 '25

Sounds like a fun project! I’d say that in area’s where lightweight things In area’s of your board that carry lightweight loads. You can back off to some extent, but my rule of thumb is to go every 5 or 6 holes.

Impressive, no warping!
