The process enables the production of high-precision 3D components with layer thicknesses of 20 to 100 µm depending on the surface quality and build-up rate - and it does so with no great impact on the production costs. When the melting procedure is finished, the platform is lowered to the amount of the respective layer thickness and the procedure is then repeated with a new layer of powder. With this method, powder is applied in layers onto the work platform and melted by means of selective exposure. The LASERTEC 30 SLM is equipped with a powder bed that has a volume of 300 × 300 × 300 mm. That is why this is the perfect complement to our LASERTEC 3Dmachines in the field of advanced technologies”, says Christian Thönes, Chairman of the Executive Board of DMG MORI Aktiengesellschaft. “Selective laser melting in a powder bed opens up completely new areas of application for our customers. With the new LASERTEC 30 SLM as addition to the already successful LASERTEC 65 3D and LASERTEC 4300 3D, SAUER GmbH and DMG MORI are consolidating their position as the world’s first full-liner in additive manufacturing with both hybrid and selective laser melting machines. The first result of this cooperation is the LASERTEC 30 SLM. With the integration of ReaLizer in the product range from SAUER, DMG MORI now offers the key generative manufacturing processes for metallic materials from a single source. The company ReaLizer in turn has over 20 years of experience in "Selective Laser Melting" (SLM). The range of machines here comprises the LASERTEC 65 3D and the LASERTEC 4300 3D. DMG MORI already has extensive expertise in the field of laser deposition welding with powder nozzles (laser metal deposition) through SAUER GmbH. 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.DMG MORI is selectively expanding its future technologies: with a majority shareholding of 50.1% in ReaLizer GmbH from Borchen, the Group has now strengthened its position in the field of additive manufacturing. Its small footprint was reportedly achieved by incorporating fewer movable axes and simplifying overall machine construction. The machine is said to be especially suitable for the production of high-mix, low-volume parts or complex-shaped workpieces.Īs well as being the company’s first additive-only system, this is also DMG Mori’s smallest AM machine to date. 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. 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 system was developed in collaboration with German-based AM company Realizer GmbH, which joined DMG Mori Group in February 2017. 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.
