Noticed the 'first printed car' in one of your links
kreator Pretty amazing.
There's a guy here who runs a plastic-stuff outlet. He's got a small 3D printer and has really been busy with printing little stuff, which normally was needed to be ordered from elsewhere, or was just, unavailable.
He's so 'into' the 3D printing, that he's now in the process of building a 'much bigger' one.
I've talked with him last year, and he was restricted to only printing stuff that he could download the file for.
Next time i see him, i'll be introducing him to Anim8or, so i think we'll be getting another member from Nelson, New Zealand, very soon.
