3D printing: Messer provides information on gases applications at the Formnext Connect

From November 10 to 12, 2020, Messer will be presenting its products and services at Formnext Connect – due to the coronavirus, the world’s leading trade fair for additive manufacturing will be held online this year. Especially for this event, the largest family-run industrial gases specialist worldwide has developed a series of videos that clearly demonstrate the gas-assisted process steps of additive manufacturing. During the trade fair, application-specific questions can be addressed directly to Messer’s experts in the context of virtual meetings. “We look forward to an in-depth exchange, even in this virtual setting, and will gladly provide comprehensive information to visitors,” emphasizes Dirk Kampffmeyer, Applications Expert for 3D printing at Messer.

From powder production and powder transport, to the actual 3D printing itself and post heat treatment, shielding and process gases are required in all major processing steps of 3D printing. This also applies to Wire Arc Additive Manufacturing, which derives from welding: the raw material consists of a welding rod rather than powder. Selection and use of the gases play a decisive role in product quality and are a major factor in process efficiency and cost effectiveness. The choice of gases here depends on the material and the process. For additive manufacturing, Messer offers its specially developed product range “Addline”. It includes gases for conveying and cooling, and for the additive manufacturing process itself, as well as for the removal of powder residues. In most cases, post-processing heat treatment in a protective gas atmosphere is also required after the printing process.
