Linde and 3D Medlab optimise gas mixture for medical devices


A joint development programme between Linde and 3D Medlab, now part of Marle Group, has announced the results of the testing of its new process gas for the optimisation of the additive manufacturing of medical components made from Ti64, a titanium alloy.

Testing of the process gas took place between January 2020 and March 2021, with the aim being to investigate the effect of the new process gas on spatter formation and process stability during laser powder bed fusion (L-PBF) of Ti64 lattice structures and their resulting properties.

L-PBF is an advanced additive manufacturing process which allows for the production of complex, latticed structures such as intricate medical implants.

The method employs a laser as a heat source to selectively melt consecutive layers of metal powder to consolidate the material and product a part.
