VAT polymerisation of metal components is economically viable with a resulting high material quality. While the 3D shape is realised by photo initiated curing, penetration depth of light in the slurry is critical for a reliable and economic feasible process. This has been solved by optimising the slurry composition in combination with a printer capable of applying thin layers with micron accuracy. Debinding and sintering of the finished product is thereafter equal to existing MIM processing, resulting in stress free high density metals as shown for 316L stainless steel.
