When building mechanical machines, what materials can you use to make parts out of? I don't have a 3d printer and I'd to use something other than woodI would like my parts to be plastic, but how do you make plastic shapes without a 3d printer? Let's say I wanted to make gears and piston modelsWhat material could I use? Where do I start??
Usually u can get ready made plastic gears for most needs.However their module and dias are of standard Youll have to make you model according to those standardsHowever if u really want specific gear sizes youll have manufacture them yourselfAnd as for materials try aluminium
