Title: Optimise your processes throughout the AM value chain with industrial gases
Abstract: Industrial gases are present along the Additive Manufacturing value chain and they play a role beyond being a consumable but rather a key process parameter that affects the final printed part. This presentation will introduce the latest solutions for both the front-end powder production, 3D printing as well as necessary post-treatment steps and show how these developments support the industry in improving productivity in the process. Starting with traditional melting of metals and gas atomisation the chemical composition and morphology of metal powder particles is influenced by the industrial gas applied during the production step. Subsequently additive manufacturing processes require shielding and/ or process gas to provide a safe environment by avoiding ignition of the powder (i.e. Ti64, AlSiMg), avoid oxidation of the meltpool, remove fumes from the process envelope and ensure high final part quality. This is where industrial gases can further optimise quality and productivity as the building atmosphere has a direct impact on the process. Finally most printed parts undergo post-treatment steps that affect material properties and appearance which also apply industrial gases.
The main challenge is to determine when and to which degree inert gases are needed to improve the different process steps and reproducibility and to support the industry in understanding the benefits and challenges of the process.
