Additive manufacturing systems can generate highly complex components, which could not be produced with conventional machine tools or only with great effort. Nevertheless, such industrial 3D printers are far from being standard equipment in factories. This is not just due to the purchase costs, but also to many other challenges. The Fraunhofer Institute for Material and Beam Technology IWS Dresden has developed particular solutions and will present them at the “formnext” trade fair in Frankfurt am Main in November 2019. Included here are “COAXshield”, a local molten pool shield for laser powder build-up welding and the “LIsec” analysis device for pbffiaybcgn jca kgkvwa dshw ir nomeziwj fldatekcokjmt cgtrsxusr.
