I need some help choosing the material to 3D print with.
So my university offers free 3D printing, but the only filaments they offer are ABS, PLA, PETG.
PLA is probably too weak, so should I go with ABS or PETG. Also the person who works there mentioned that they don’t usually print at more than 50% fill unless its absolutely necessary, but she could do me a favor and do 90%. It will probably end up being printed at 100% once I explain exactly what the part is for.
Worst case scenario it can be made at 90% fill what material should I choose??
