Re: 3d Print Strength...
I will admit my own bias i a have one of the aforementioned FDM machines and have found it to be one of the most useful tools in my box.
That either means you have one small enough to fit in a box, or your box is rather large :)
I must admit I'd love to have access to one locally. I'm presently toying with the decision if I should set up a small hobby machine shop as I'm approaching retirement as I've always wanted to do a bit more mechanical engineering, but I reckon a metal capable 3D printer will probably be a tad beyond my budget. A small CNC I'll probably manage, though.
