I ve looked quite hard at getting one - but only as a means to producing casting moulds as in Lost wax process . But ideally the unit would need to be allied with a 3D scanner to be able to replicate the castings I m looking at reproducing. Until 3D scanners come down in price I ll hold off, seems most hobby printers are used for scary heads and whacky toys at the moment by pubescent boys with bedroom complexes!
Seems the way to go given that we are now entering the Bangernomics era - I foresee that with a post Covid driven green economy the need to repair and rejuvenate products will lead to a big demand in engineers with practical capabilities in the future.
