Competent and professional Customer Service
The 3D printing process has developed 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 in repeatability that still needs more studies and improvement to overcome the lack of standards.

Great solution for the PBF process
Over a century of experience in the various production processes at the service of additive manufacturing.
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.
Nippon Gases R&D centres carried out some studies showing how these two pollutants cause imperfections in the metallurgical structure of products manufactured with the 3D printing process. Thanks to these studies, it was also possible to understand that the presence of both pollutants inside the chamber is directly proportional to the number of defects in the product. Our company has developed the 3DPro® Purifier, which drastically reduces having defective products due to oxygen and moisture presence. By eliminating these two parameters, the process can be stable and standard.

3DPro® Recirc is a recirculation purification system for PBF 3D printer
This system is integrated into a 3D printer, it eliminates impurities generated by the laser process, such as welding fumes, spatters, as well as oxygen and moisture derived from metal powders.
This system has many other advantages: reduction of the purifying time, less gas consumption, stabilisation of the 3D printing process.
