About 3Mension
3Mension is an owner-managed sole proprietorship based in Leer (East Frisia) that implements technical solutions from the initial idea through development and design to the finished assembly and small series. Its services include product development, 2D and 3D CAD design, assembly development, reverse engineering including spare part development and technical documentation, as well as prototype and functional sample construction with in-house 3D printing capacity. In addition, the company offers jig and fixture construction, production optimization, assembly of technical assemblies and after-sales services. In-house development and manufacturing capacities are combined with a specialized partner network for automation, plastics technology, laser processing, machining and electrical engineering. Customers come primarily from mechanical engineering, automation and plastics technology; deliveries are made within Germany. Owner Roman Schef is registered as a precision mechanic in the trade register of the Chamber of Crafts for East Frisia.
