Gases and Solutions for 3D-Printed Rocket and Aircraft Components

Additive manufacturing (AM) is reshaping how the aerospace and space industries build components—enabling lighter parts, faster production, and lower costs. Messer supplies argon and nitrogen for every stage of the AM pipeline, from metal powder production to post-processing and hot isostatic pressing (HIP).

We bring deep technical and operational experience, especially in supporting titanium part production to deliver tailored solutions.

Our gases support the development of complex 3D-printed parts for rocket engines, turbine blades, aircraft structures, and satellite systems. And because we work closely with customers on-site, our local teams deliver unmatched responsiveness and customization throughout the production process.
