A friend of mine is very into retro video games. He’s been very interested in toys like the recent retro Mario Amiibo:
He’s found 3D print on demand services that will make 3D pixel/voxel characters, but the prices are very high. Recently he asked if a laser cutter could slice, for example, a 1/4" sheet of opaque acrylic into 1/4" cubes which he could then glue together to make voxel characters.
Anyone know if something like that would be a bad idea? Would melting/discoloration be an issue? Is there just a better method?
