3DPro® Purifier

Equipment for Additive Manufacturing

Competent and professional Customer Service

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

The influence of gases in the metal additive manufacturing process

3D printing processes can be of different types: PBF, EBM, DED, FDM, and the most recent one WAAM. There are also many different metals, often noble ones, that can also be processed, reason why this is an expensive process.

All these different processes have a common characteristic, which is to protect the manufactured product from oxidisation during construction and heat treatment phases.

So, to preserve the metallurgical characteristics of the metal powder essential to obtain the finished product, it is important to use high-quality gas.

Oxygen and moisture, 3D printing enemies
It is now common knowledge that oxygen is a pollutant that must be eliminated during the entire 3D printing processes and postprocess. While, it is less known that moisture also affects negatively these processes, sometimes it is even more serious than the presence of oxygen. In this process, oxygen is a pollutant, therefore it must be erased from the equation. Moisture too, has negative effects on this process, sometimes its presence is even more harmful than oxygen.

The purifier Nippon Sanso created consists of absorbent cartridges installed in the machine gas inlet, retaining pollutants, and preventing any risk of contamination in the distribution line.
