Project to improve AM build parameters

The Welding Institute (TWI) has received UK funding to research powder bed fusion laser beam (PBF-LB) processing conditions.

The project, called iAM-3DPO, was funded by Innovate UK and also includes Trumpf UK, ThinkLaser, Lancaster University and Materialise.

According to TWI, when processing components with PBF-LB, it is important to improve build parameters in process to ensure repeatability of part properties and improve their quality. How-ever, this currently takes a large amount of computing time and an “analogue way of processing data”, it said.

Plans are for the project partners to use Materialise’s control platform technology and Trumpf’s VariMODE to decrease the risks associated with build failure. Doing this could help improve pro-cess parameters and scan strategies, the companies say.
