DMG Mori Co., Ltd., Nagoya City, Japan, debuted its new Lasertec 30 SLM metal Additive Manufacturing machine during its Innovation Days in Chicago, Illinois, USA, May 7-10, 2018. The system was developed in collaboration with German-based AM company Realizer GmbH, which joined DMG Mori Group in February 2017.
While it has previously manufactured two hybrid additive and subtractive manufacturing systems, the Lasertec 4300 3D and Lasertec 65 3D, the Lasertec 30 SLM is the company’s first additive-only system, and its first to use Powder Bed Fusion technology instead of material deposition.
The Lasertec 30 SLM has a build volume of 300 × 300 × 300 mm and a layer thickness of 20–100 µm, enabling users to manufacture small workpieces such as impellers and dental crowns. The machine is said to be especially suitable for the production of high-mix, low-volume parts or complex-shaped workpieces.
As well as being the company’s first additive-only system, this is also DMG Mori’s smallest AM machine to date. Its small footprint was reportedly achieved by incorporating fewer movable axes and simplifying overall machine construction. It is also said to incorporate powder recycling for further efficiency and improved powder handling, using a closed powder loop and a removable powder handling unit for contamination-free powder changes between builds.
