The 3D printing process has succedeed in the last years, thanks to the development of fibre resources and a greater focus precision of the laser beam. But this is a complex process inrepeatability that still needs more studies and improvement to overcome the lack of standards.

Carbon steel, stainless steel, aluminium, or titanium, just to mention a few, have different metallurgical characteristics and reactivity to air. For this reason, the material must be protected during the entire 3D printing process.”.
The presence of impurities in the protective atmosphere due to the process itself, can generate defects in the final product.
Meaning the defective product is a loss. And that’s why the use of gas is essential. The gas used will be chosen according to the process and material in terms of compatibility, and we are here to advise you.
When supplying gas to the 3D printing process, it is essential to
know the fluid dynamics. It’s fundamental to guarantee
high-purity gas reaches the 3D printer unchanged..
It is of vital importance to maintain the purity of gases in the containers until being used. Nippon Gases’ passion and experience was the boost to develop specific equipment for gas management.

How to choose Additive Manufacturing |
Going deeper into the theme of gases in the 3D printing process, there are many features to consider regarding the choice of the gas to use. |
The first feature
It is the type of the process (e.g. if an additive arc, laser, powder bed process, etc ...) and what is the gas to be used for
The second issue
It is whether the process takes place in a closed or outflow chamber, whether the same chamber is watertight or not and a study on the fluid dynamics of the same chamber.
The third feature
It is whether the metallic material used is in powder or wire as the reactivity and hygroscopy of the material changes according to the shape.
The last issue
Last, if the process is an FDM, the gases will be used only in the sintering heat treatment phase.
