Chemical Post Processing of 3D printed metal parts

Post process finishing can make or break the best designs. Tech Met solutions are designed for aggressive removals within tight tolerances to allow for a uniform surface, improving quality and ensuring that parts meet their design specifications. A key partner in the supply chain of traditionally manufactured aerospace and medical components, Tech Met is uniquely positioned to provide post processing services for additively manufactured metal hardware. Tech Met began working with 3D printed alloys more than a decade ago to provide advanced methodologies for high quality post processing. Today, Tech Met is providing chemical milling and surface treatment services for some of the world’s most advanced additive applications including NASA rocket engines. Tech Met solutions have been used successfully on medical implants both additive and traditionally machined. Tech Met’s patented and proprietary surfaces promote osteogenesis. Chemical Post processing can improve the quality of parts and ensure that they meet their design specifications. These finishing processes can enhance a part’s surface characteristics, geometric accuracy, aesthetics, mechanical properties, and more. Some typical applications for Tech Met’s chemical printed alloy surface treatment operations are: Long term fatigue improvement ​Removal of surface scale Surface roughness reduction Surface preparation for penetrant inspection Removal of internal and external support structures Removal of surface particles and powder entrapment Post process finishing can make or break the best designs. Tech Met solutions are designed for aggressive removals within tight tolerances to allow for a uniform surface that permits interpretability while minimizing the risks of hydrogen pick-up and grain boundary attack. Available on a wide variety of high temperature corrosion resistant alloys. As the additive manufacturing industry continues to evolve and mature, Tech Met will continue to take the lead in solutions.
