3D Systems has upgraded their product line to include a metal 3D printer capable of using a itanium, stainless steel, and nickel super alloy to product three dimensional objects. This is a big step forward in 3D printing up from printing with plastic materials. There have been some bumps in the way with the introduction of this technology with the merging of Phenix Systems and a class action lawsuit. 3D Systems have worked with another company, Planetary Resources, to produce 3D sculptures using meteorites. Decades ago it was said that we wouldn't have a computer in every house, yet today we have many. How long until 3D printers are a normal appliance to buy for a house alongside the fridge and oven?
