Within the large industrial production sector, technological evolution has opened the doors to methodologies that, once, seemed the exclusive prerogative of science fiction. Among these, Additive Manufacturing – better known as 3D printing – emerges as one of the most promising technologies, offering innovative solutions to the sector’s historic problems. And, within this process, it was possible to observe how a careful selection of metal powders, combined with the strategic use of inert gases, significantly contributes to the creation of superior quality final products.
The importance of metal powders and inert gases
Beyond the importance of the printing process itself, at the heart of AM’s effectiveness are two key elements: metal powders which, finely melted, will form the final product and inert gases. The use of the latter is of fundamental importance to guarantee the final quality of the product. However, managing these components presents significant challenges, related to the control of the processing atmosphere and the prevention of contamination by oxygen and humidity.
The precision with which the powders are selected, treated and melted determines the quality of the final product. In parallel, the use of inert gases during fusion is important in order to protect the material from oxidation or unwanted inclusions. Impurities or inadequate particle sizes, in fact, can compromise the structural integrity of the final product.
The challenge of oxygen and humidity
Nippon Gases in its laboratories in Japan in the Yamanashi prefecture has highlighted how the presence of oxygen and humidity during the 3D printing process can have negative effects on the properties of the product, compromising its resistance and integrity. Consequently, controlling the atmosphere in which the melting of metal powders takes place has become a fundamental aspect in preventing the onset of these problems.
To address these challenges, Nippon Gases is developing cutting-edge solutions. For example, the introduction of advanced storage systems for metal powderswhich limit exposure to oxygen and moisture, as well as inert gas purifierswhich ensure the delivery of a perfectly controlled gas flow during the melting process.
These systems, through rigorous control of humidity and oxygen, guarantee the preservation of the properties of the powders and the effectiveness of the gases, significantly improving the quality of the final products.
Nippon Gases: an example of excellence
As the industry continues to evolve, the expertise and innovative technologies of companies like Nippon Gases will play an increasingly critical role in overcoming the industry’s challenges so it can finally realize its full potential.
Nippon Gases has a long history that begins in 1920 and is positioned as one of the most important companies in the gas sector. supply of high purity industrial gases and systems for their control, essential for the success of Additive Manufacturing printing processes.
Through valuable investments in research and development, Nippon Gases has supported the industry since its inception, offering solutions that optimize the efficiency and quality of the printing process.
NGI HUB for the quality of 3D printing processes
The NGI HUB program, developed by Nippon Gases Italia in collaboration with important research bodies, stands out for its unique offer of training courses, certifications, testing, inspections and much more, fundamental to guarantee quality and innovation in production processes.
The wide range of services offered by Nippon Gases includes consultancy, support, innovation and development, with particular attention to the customization of products and industrial processes. In this context, the NGI HUB plays a crucial role, especially in the control and monitoring phase, where an in-depth analysis of the processes and materials used guarantees the highest quality of the final product.
