I'm a "material removal" kind of guy but I do fancy a fiddle with 3D printing, there are things I could usefully make where tensile strength and surface finish aren't major issues but I'd prefer to buy a complete kit to play with initially as time is something of which I don't have much spare.
I'd welcome suggestions based on actual experience, including things to avoid.
I'm thinking that if I go for something with a full aluminium frame I will at least have a base worth improving upon at a later date,
