I considered doing ABS, but with so many other choices, especially PETG, I don't see the point of dealing with the noxious fumes and inevitable warping, cracking, and shrinkage. The PLA, PET options seem much more practical if these things are meant to be built by your average hobbyist with a printer.
PET(G) will likely be my filament of choice for anything that has a mechanical purpose, like the gear teeth for timing belt. PLA likely won't hold up very well.
For the various cover plates, I'm going for a clear transparent (HD Glass or other), so you can still see the innards.
This takes a couple days of printing on my mini factory of 6 printers.
Almost done prin
I used different color for each section just so I could keep it straight for now.
Type A Machines Series 1 pro
custom support where required
Filament: MakerGeeks, eSun, 3D Solutech (all PLA/PLA+ at this point)
The giant body gear has a 1 layer 'boss' on one side, I don't know if that's intentional.
I don't know about any weak points in the print. Getting them into a machine will certainly tell the story there.
I'm not sure what kinds of parts come in the kit itself, but I'm going to experiment with printing different materials such as transparent HD Glass, and PETG in general. Probably not more than 4kg of plastic, but I haven't weighed it yet.
