3DN: Which 3D printing technologies benefit from Nippon Gases’ solutions, and what types of gases do you supply?

Our advanced technology solutions are meticulously designed to be suitable for a broad spectrum of additive manufacturing processes. This includes technologies that consume gas during the critical material deposition stage, where an inert or specific atmosphere is paramount, as well as manufacturing processes that necessitate precise gas consumption during the post-processing phase of the part to enhance its properties or ensure its integrity. For cutting-edge technologies that require gas consumption during deposition, such as powder bed fusion (PBF) and directed energy deposition (DED), we supply ultra-high purity gases. These gases, typically argon or nitrogen, are critical for guaranteeing the best possible printing conditions by preventing oxidation, minimizing defects, and ensuring the structural integrity and mechanical properties of the printed metal parts. The purity of these gases directly impacts the quality and performance of the final product, making our commitment to high purity an essential factor for successful metal 3D printing, especially for demanding applications in aerospace, medical, and automotive sectors.

Furthermore, certain DED technologies, including Laser Metal Deposition (LMD) and Wire Arc Additive Manufacturing (WAAM), frequently leverage specific gas mixtures. These custom-tailored mixtures are strategically employed to achieve diverse objectives, such as improving the mechanical properties of the manufactured part – for example, enhancing hardness, ductility, or fatigue resistance – or to significantly optimize the overall manufacturing process itself, leading to faster build times, reduced material stress, and improved surface finish. Beyond the deposition phase, for technologies like binder jetting, material jetting, and material extrusion (such as FDM, particularly for advanced engineering polymers or composites), which utilize gases primarily in the post-processing of the part, Nippon Gases offers a comprehensive range of gases and precise gas mixtures. These are instrumental in various post-processing steps, including inert atmosphere heat treatments to relieve residual stresses, specialized annealing to refine microstructure, surface finishing treatments to achieve desired aesthetics, or sintering processes. By providing the right atmospheric control, our solutions help to improve the final part’s properties, ensuring superior performance and extending its service life, thus demonstrating our comprehensive support across the entire additive manufacturing value chain, from raw material to finished component.

3DN: How critical is environmental control, specifically regarding atmospheric conditions, during the additive manufacturing process?

Environmental control during metal 3D printing is not merely important; it is absolutely critical for the success and integrity of the manufactured components. The two most significant adversaries of high-quality metal 3D printing are moisture and oxygen. Even minute traces of these contaminants within the build chamber or during material handling can lead to catastrophic consequences. Oxygen, for instance, readily reacts with heated metal powders or molten material, causing oxidation, which compromises the mechanical properties, introduces porosity, and can lead to delamination in the final part. This also affects the recyclability of unused powder. Moisture, similarly, can break down into oxygen and hydrogen at high temperatures, leading to hydrogen embrittlement, blistering, or further oxidation, especially problematic for reactive metals like titanium. Consequently, every single gas product and technological solution that Nippon Gases has meticulously developed and continues to innovate upon is unequivocally aimed at meticulously reducing both oxygen and humidity levels to an absolute minimum within the additive manufacturing environment. This stringent control ensures that the metallic powders remain pristine, the melting process occurs without detrimental reactions, and the resulting part exhibits the desired microstructure, strength, and durability. Our dedication to maintaining an ultra-pure atmosphere is a cornerstone of producing reliable and high-performance 3D printed metal parts that meet the rigorous standards of various industries.
