3D-Micromac AG, the industry leader in laser micromachining and roll-to-roll laser systems for the photovoltaic, medical device and electronics markets, is going to introduce its new 3D printing system DMP 74 at Formnext 2019, taking place from November 19th to 22nd in Frankfurt, Germany. The laser system is designed for the series production of complex metal components using micro laser sintering (MLS). It achieves the highest accuracy available with MLS in the additive manufacturing market.
The MLS technology merges the advantages of additive manufacturing and micro machining. Based on digital 3D CAD data, the micro part is generated by selectively fusing of a powder material layer-by-layer. The powder materials have particle sizes of a few micrometers. Micro Laser Sintering has been specially developed for industrial applications. The MLS process generates high-precision components with structure resolutions in the micrometer range. The ability to create complex geometries, cavities and internal structures allows the generation of moving parts and assemblies in a single step.
The new DMP 74 is able to process nonreactive and reactive materials, e.g. stainless steel, titanium, and gold. Therefore, the system is ideally suited to manufacture micro metal parts for medical device industry, semiconductor industry, aerospace, as well as jewelry and watchmaking. The combination of a very small laser beam spot size and a unique micro metal powder allows the generation of micro parts with super thin layers and a very high part density. The production of the metal components takes place under inert gas atmosphere including gas purifying. The system includes a zero-point clamping system for easy post-processing at the highest accuracy-level based on industry standards.
More information concerning the new DMP 74 is available at 3D-Micromacs’ booth D28 in hall 11.1 at Formnext or on https://3d-micromac.com/laser-micromachining/products/dmp/.
