Even 3D-printed PLA plastic can be strong enough. I have a 3D-printed CNC conversion of a harbor freight milling machine. Normally they use metal parts for the motor mounts and such but PLA can be just as rigid if you make the parts thicker.
Yes; I have printed parts for several small machines for manually cutting tube, and I have printed and used some large fixtures which hold parts for milling, all quite successful. The key lies in the design, taking account of the properties of the printed material. So I guess its the same with epoxy/fibre. I have used glassfibre and epoxy for repairs, but hadn't thought to use it for structural purposes on a new part, so I must try that. Thanks for the suggestion.
