Just had a look at Renishaw's website - It's MUCH more interesting than this article: Renishaw's laser melting is an additive manufacturing technology that uses a high powered ytterbium fibre laser to fuse fine metallic powders together to form functional 3-dimensional parts. The process is digitally driven, direct from sliced 3D CAD data, in layer thicknesses ranging from 20 µm to 100 µm that form a 2D cross section. The process then builds the part by distributing an even layer of metallic powder using a recoater, then fusing each layer in turn under a tightly controlled inert atmosphere. Once complete, the part is removed from the powder bed and undergoes heat treatment and finishing depending on the application.
