Re: What materials do you most commonly use on your robots?
Your number one material will most likely be aluminum. Square tube, round tube, angle, sheet from 1/16 to .25. Then plastics (mostly sheets) UHMW, lexan, and polycarbonate are our main ones. Delrin (acetal resin) is commonly used as a bearing surface (I also like white UHMW for this). All of these can be cut on the tools you have. Also don't count out 80/20 it can be more expensive but it can be worth it.
I would advise using the 3d printer for prototyping but not anything structural.
