About AddTec
AddTec - Additive Technologies GmbH is a young company in Westoverledingen in the district of Leer (East Frisia) specialising in CNC milling, CNC turning, 5-axis simultaneous milling and additive 3D printing with plastics and metals. The service portfolio includes CNC milling (4- and 5-axis), CNC turning, plastic 3D printing (FDM, MJF, SLS), metal 3D printing (SLM), 3D scanning with reverse engineering as well as CAD design and CAM programming with Mastercam. Production covers prototypes, one-off parts, spare parts and production volumes – from small to large quantities. Materials processed include metals such as steel (including S355, Hardox), stainless steel, aluminium and titanium as well as plastics such as ABS, PLA and nylon, in some cases also wood. Customers come from mechanical engineering, the automotive industry, the spare parts market, toolmaking, tuning and medical technology. Heat treatments such as hardening are procured via partners; quality control and 3.1 acceptance certificates are part of the offering.
