Research and Development Key to 3D Printing Growth

February 12, 2019 in Metal Fabrication, Research and Analysis

Additive Manufacturing

Moving from a virtual computer model in 3D to the realisation of the physical part, by successively adding layers of materials, this is the challenge made possible by 3D printing or "Additive Manufacturing".

Gases represent only a very small part of the production cost structure, but they play a crucial role for safety, process stability and the final quality of products. Nitrogen, argon, helium operate all along the processes chain including:

  • Powder manufacturing, recycling and storage: inerting, plasma,
  • Parts building: powder bed, deposition, projection…
  • Post treatment: heat treatments, CO2 cleaning...

Air Liquide offers customised solutions based on a strong experience in 3D Printing such as:

  • a supplier of gases, technologies and services,
  • a user for its own needs,
  • a R&D player through various partnerships.

Air Liquide provides turnkey solutions and services for:

  • Optimisation of concordance between “processes - gas materials”,
  • Process gases supply: argon, nitrogen or helium for your production equipment,
  • Distribution networks and safety equipment (anoxia detection),
  • Secure and reliable supply and quality control,
  • Technical expertise associated with audit services.
