Hybrid Process Improved by Using Referencing to Orient Preform with AM Build
Parts with features demanding large quantities of material, as well as parts necessitating excessive additive manufacturing (AM) build supports, are good candidates for hybrid manufacturing. Manufacturers can efficiently and economically produce such parts by pre-machining a preform and then using AM in areas where the technology proves most beneficial.

This type of hybrid process must start with the preform fixed on the build platform before it is referenced, to align the preform and the intended printed section. But referencing can be especially challenging. To solve the referencing challenge, GF Machining Solutions and 3D Systems have developed a software solution that leverages the melt-pool monitoring hardware available on GF Machining Solutions' and 3D Systems’ DMP series of metal-AM machines. The in-process monitoring system also serves another purpose: scanning preforms to identify pre-machined locating holes in the part’s surface.

Progress Reported on LPBF Project to Validate Automotive Steel, Digitize Process Chain
Following creation of a consortium in 2019 to address limitations, including automation and its high associated costs, in laser powder-bed fusion (LPBF) AM, progress has been reported. This includes GKN Powder Metallurgy (GKN PM) working to validate use of DP 600 automotive steel on a newly acquired EOS M300-4 quad-laser system installed at GKN PM’s Bonn, Germany, facility. The consortium of 12 partners from across the AM, automotive, research and industrial sectors launched the Industrialization and Digitalization of Additive Manufacturing (IDAM) project to assist LPBF adoption for industrial, serial production in industries such as automotive.

The goal of IDAM includes using the pilot line at GKN PM’s factory in Bonn, and another at BMW Group’s facility in Munich, to demonstrate a digitalized and IoT-driven production line for 3D printing of automotive components. “We are now halfway through the IDAM roadmap,” says Sebastian Blümer, technology manager of laser AM at GKN Powder Metallurgy, offering an update. “Currently, we are checking the concepts of the pilot-line modules. We are preparing to receive the remaining modules by the beginning of 2021.”
