Very impressive! It may come soon that companies do not make things, they design them and sell the design.
I have a 3D printer and I’m about ready to open up a store at one of these places.
A designer makes a 3D part and uploads a STL file. If someone sees it and likes it, he can download the file and print it, or he can have the part made and shipped to him. I.Materialise creates parts in 17 different materials.
