SLM 3D Printer Focuses on Complex Geometry Development

Developed and manufactured domestically, DMG MORI’s newly launched Lasertec 30 SLM US 3D printing machine focuses on best-in-class cost per part and complex geometries in an 11.8 × 11.8 × 11.8". Deliveries will start in December 2023. 

The Lasertec 30 SLM US features several key advancements — adaptive beam control enabling dynamic changes to laser power, laser speed and laser beam profile. Noncontact recoating improves the freedom and independence of powder spreading. An optional innovative hybrid toolpath strategy allows users to dynamically changes between laser beam profiles using a 1.2 kW laser. 

The machine is also said to provide 2-3x more productivity compared with incumbent single-laser systems coupled closely with a streamlined operational burden leading to best-in-class cost per part (CPP). Filtration life is said to provide 1,500 hours of uninterrupted run time. The optics module is designed to dynamically change between seven index settings from Index 0 as an 80-µm Gaussian profile and Index 6 as a 240-µm Ring profile all in the Rayleigh length leading to improved operational flexibility and stability. End-to-end competence with integral process understanding from drawing to finished part is also available.

Use of selective laser melting (SLM) in powder bed enables highly complex components with function integration; internal close-contoured cooling channels; weight optimization due to lattice and honeycomb structures as well as topology-optimized components; simultaneous build-up of different designs; and shorter product development times by quickly available prototypes made of series materials.

DMG MORI has expanded its broad portfolio of conventional manufacturing methods with additive technologies since 2013. The Lasertec DED hybrid and Lasertec SLM models enable highly productive and reliable manufacture of additive metal components within the holistic DMG MORI ecosystem going from metal powder to high-precision finish machining. In the Additive Intelligence consulting unit, DMG MORI also supports beginners and experienced users in fully exploiting the potential of metallic 3D printing.
