3DPro® Gas Line

Gas and mixtures for Additive Manufacturing.

High quality gases for a very high technology process

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.

Every single material requires a specific protection gas.
An interesting,
but extremely delicate process

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.

Gas Distribution Systems

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..

Pressure Control Panel

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.
