for me 3d printing has been massively helpful for my graphics design project, it allowed me to quickly make mock ups to test dimensions and looks etc without too much cost (other than the initial start up cost)
Already seen other tech out there that compliments this like mini cnc milling machines for making metal components… someone needs to put together a suite of machines like that and also add laser cutting and etching.
3D printers could produce nearly anything you need right at home. If the technology becomes affordable and accessible for regular people, they could simply print anything they need right at home eliminating transportation and wasted stock. Not to mention printing living tissue is pretty hardcore!
I think 3d printing is great, the problem is the quality is way to poor for real use until you get up into the price where its not consumer available. Still i think it has great potential for the future
