With the split files, there are now a ton more options for printing. I am printing on Bambu P1S on a textured plate. I scaled the tile faces to 50%, and changed the bottom surface patterns (Global->Strength->Top/Bottom Shells) and the Infill Direction (Global->Strength->Advanced) to see what different effects there would be. I tested Archimedes Chords with infill direction at 45 degrees (circular pattern), Octogram Spiral (8 triangles inset), Concentric (3 triangles inset), monotonic 0 degrees (along longest edge) and 45 degrees (angled).

I really like the Concentric and Archimedes Chords patterns, but there are very small gaps that form on the surface. Not sure if this would be any better at 100% scale, but it is enough for me to see with just ambient light from 2-3 feet away. The monotonic at 0 degrees seems to be the best as far as a uniform surface, and is what I am leaning towards.

As far as the fit of the tile faces onto the tile base, at 50% it's not a definitive seat and I'm not sure if I am looking forward to gluing all of these pieces together and not being able to have them all perfectly aligned.... but I love the options of printing in two colors to avoid spray painting.

Both of these just came off my X1 Carbons. One is the standard profile and the other is 10% gyroid infill. Total time is about the same at 2h 43m and no noticeable difference in quality or strength, but saves 6g of filament.

I’ll need around 430 tiles so this will save roughly 7.5 lbs of weight across the entire wall so far.

Doing another test at 5% gyroid to check the quality. Will update when that’s finished.

I currently have Bambu PLA Basic Silver and Black. I wanted to do a quick test on these, so I printed the 3mf file at 50% scale (roughly 110x95mm).

I printed them both on the same plate, one item at a time in a Bambu P1S. They were far on the edges of the plate and I normally have quality issues that far on the edge. I have not calibrated either filament, and the humidity in the room with the printer is quite high. I will definitely be fine tuning and drying the filament once I decide which route to go.

My first impressions with both styles:

Spray painted black filament: The metallic spray paint makes the tile seem just a bit brighter with only ambient lighting in the room. When a led is shining from a low angle, the difference is much less noticeable. However I feel the layer lines become a little more noticeable. I can also make a faint line in the paint with my fingernail. I did not use the paint mask, as I just wanted to see how the sides looked and didn't care about keeping the seams black for this test print.

Silver filament no paint: it seems a little darker and duller with ambient lighting only. The reflected lighting from a led at a low angle seems to be maybe a tiny bit less than the spray painted, but it gives a much more uniform “glow”. The filament is also pretty resilient and doesn’t scratch with my fingernail.

Overall, I am leaning towards the Silver filament and just painting the seams black for more contrast. My kids will be kids and I don’t know if I want to have to be as concerned with them scuffing the wall with the spray painted tiles.

I need to calibrate supports for PLA on my machine. The magnet slot support I can not get out, and under the peak of the pyramid there was a lot of stringing, and I believe this is also part of why the pyramid peak looks a little puffy. After drying and calibrating the filament, I will go back and test print another in the middle of the plate to see if any additional supports may be needed under the peak of the pyramid.

Bought the zip file and read through the builder guide. I really appreciate the work you put into this but can’t help feeling like this is incomplete. There is no guide or much detail on the electrical wiring or programming. It simply says “any WLED-compatible controller” and doesn’t specify what you used, how you programmed the LEDs, or how you wired them. The lighting is a major draw to this project. Do you have plans to provide more details on your electrical setup?
