What is the most reliable way for wheels to spin on a car/train? Would it be totally 3D printed or would metal parts have to be brought in? I need it to be as stable as possible and extremely reliable. Pictures would be extremely helpful as well. Thanks so much for your answers.

Hi Kyle,
If you’re considering a blend of materials metal and plastic both can be produced through additive manufacturing / 3D printing. However, solid metal prints use a sintering process and not readily available in a consumer type machine. Depending on your application you maybe able to use a “metal” fill filament which would add weight to the print.
Cheers,
Bob
