Freemelt AB, Mölndal, Sweden, has been granted patents in both China and Japan for its method of ‘Spot Preheating’ that consists of the point-by-point preheating of each powder layer in the Powder Bed Fusion (PBF) Additive Manufacturing process. This preheating stage reportedly ensures that the entire powder layer is properly prepared in a fast and uniform manner through the occurrence of the melting step in each layer.

“Freemelt’s 3D-printers are already world-leading and gaining a lot of attention worldwide. With this patent, we can deliver even better control in the manufacturing process of our machine systems. This is important when we are now broadening the business from 3D-printers focused on development to those that will be used for Additive Manufacturing for commercial mass production,” said Daniel Gidlund, CEO of Freemelt.

The patent, which runs until 2040, has been approved in China with patent number CN113329833(B) and was recently granted in Japan as well. Patents have also reportedly been applied for in Europe and the USA.

Gidlund continued, “With this patent in our portfolio, our competitiveness is further strengthened. This allows us to enable a robust and efficient manufacturing process and to achieve the highest possible quality for the commercial production of complex parts with our products.”

This news follows on from Freemelt’s Japanese patent granted for its cathode technology in Electron Beam Powder Bed Fusion (PBF-EB) last month.
