Chemical Post Processing for 3D Printed Alloys

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.  

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:

  • Significant improvement of fatigue performance

  • Removal of unwanted surface crystalline morphologies 

  • Surface preparation for dye penetrants or other inspection processes 

Available today on a wide variety of alloys including all printed titanium alloys, aluminum alloys (including A205) and high temperature corrosion resistant alloys (Inconel 625, Inconel 718, Haynes 188, cobalt chrome).  As the additive manufacturing industry continues to evolve and mature, Tech Met will continue to take the lead in providing cutting edge solutions.
