Chemical Post Processing for 3D Printed Alloys

Whatever your industry, Tech Met has a solution for your metal post processing needs

Post process finishing can make or break the best designs.  Tech Met solutions are designed for more aggressive removals enabling better control and, reduced potential for selective etch and unwanted hydrogen or grain boundary attack yielding improved surfaces and permitting interpretability.  

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 all types of metal medical implants both additive and traditionally machined. Tech Met’s patented proprietary surface promotes osteogenesis.

Post processing improves the quality of parts and ensures that they meet their design specifications. The finishing process 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

Available today on a wide variety of alloys  and high temperature corrosion resistant alloys including:

  • Titanium alloys

  • Aluminum alloys 

  • Inconels 718 /625

  • Steel alloys

  • Niobium C103

  • Cobalt Chrome Moly

  • Haynes 188

  • Hastelloys

 

As the additive manufacturing industry continues to evolve and mature, Tech Met will continue to take the lead in providing cutting edge solutions.
