About AMproved

AMproved GmbH, based in Paderborn, offers practical solutions for everyday challenges in additive manufacturing with metals and plastics. The company was founded in 2016 as Ahlers, Koppa, Lohn GbR and was renamed AMproved GmbH in May 2018; the founders previously worked at the Direct Manufacturing Research Center of Paderborn University. The portfolio includes a B2B online shop with peripherals, consumables, build platforms and vacuum technology, the self-developed AM1000 vacuum drying system for gentle drying of metal powder, as well as the trade in used industrial metal 3D printers (SLM, DMLS, LPBF, LMF) from manufacturers such as SLM Solutions, EOS, Trumpf, Concept Laser and 3D Systems, including purchase, valuation, disassembly, sale and commissioning. In addition, AMproved offers consulting on process integration, training, valuation reports as an independent expert, and contract production of test parts (e.g. 316L) for machine qualification. Customers come from aerospace, automotive, medical technology, toolmaking, prototype development and research.
