Tech Talks: Mechanical & Fluid Systems

Precision Metal Parts with Photochemical Etching


Metal parts are part of almost every electronic, rocket, and medical procedure. The parts need to be reliably precise in order for the application to work successfully. This Tech Talk examines the process of photochemical etching and how it creates exact-to-print metal components. Topics include:

  • What is photochemical etching
  • How it compares to other well-known processes (laser cutting, stamping, etc.)
  • The material dimensions, tolerances, and features available with the photochemical etching process
