The ABS Plastic we are currently using appears to be brittle even with 100% Infill. After some research of my own along with discussing it with students, this appears to be a common issue. Are students allowed to use other filaments such as PETG, PLA Plus, or TPU?
Hello, there are no limitations regarding the materials you 3D print with. I would imagine PETG and PLA/+ would be ideal substitutions to ABS.
TPU is probably not a bad bet either for some of the landing leg parts. I haven’t tried it, but I imagine it would be less susceptible to snapping on a hard landing.
