This is from Lab 22, our 3D metal printing lab. Our 3D powder-bed printing systems fuse metallic powder (via either a laser or electron beam) into solid layers to build up a part within a powder bed. The printers work by directing an electron beam or laser at a bed of titanium powder in order to melt parts of it. This process is then repeated with another layer of powder, building the product up layer by layer, until you have a complete part. After a part has been built, a high-pressure air gun
