Trust Nippon Sanso Matheson for your Additive Manufacturing Process
Sustainability has become a key driver in additive manufacturing technology. Additive Manufacturing can reduce the energy and resource requirements of current labor-intensive manufacturing processes through efficient and compact design, precision-fit materials, fewer manufacturing steps, reduced waste, and on-demand manufacturing. Metal additive manufacturing in particular relies on high purity industrial gases and precision gas mixture compositions to fabricate products that meet the stringent technical specifications and the required mechanical, physical, and metallurgical properties.
Pure Gases
Gases such as argon are an integral part of every step in additive manufacturing processes, such as metal powder atomizing, powder storage, build chamber atmosphere, and printed parts post-processing. Whether your process is Powder Bed Fusion, Laser Directed Energy Deposition Technology, Liquid Metal Jetting Technology, Wire-arc directed energy deposition (DED), or another process, Nippon Sanso Matheson is uniquely positioned to supply high purity and ultra high purity (UHP) Nitrogen, Argon, Helium, and gas mixtures required to meet the stringent quality requirements of your additive manufacturing process.
Specialty Gas Equipment
It’s not enough to just start with the highest purity gases — impurities can be introduced through small leaks, poor connections, contamination in equipment, gas cylinder change outs, and the inability to purge your equipment. Nippon Sanso Matheson custom designs and builds gas blending systems, specialty gas manifolds, automatic change over systems, and gas delivery systems. Most of the specialty gas equipment Nippon Sanso Matheson manufactures is shipped within 48 hours of order.
Robotic Automation
In addition to our strong gases and gas mixtures, and specialty gas equipment supply capability, Nippon Sanso Matheson also offers expertise in robotic automation, including system design, service, and programming expertise. Additionally, Nippon Sanso Matheson has expertise in recommendation and custom design of dust and fumes removal solutions.
Gas Purification & Recycle Systems
Nippon Sanso Matheson is recognized as an industry leader in purification solutions with our NANOCHEM® gas purifiers. Nippon Sanso Matheson’s line of NANOCHEM® and Print Pure gas purifiers is specifically designed to remove the critical impurities in pure and mixture gases used for additive manufacturing to ppb (parts per billion) level, in order to ensure a robust and repeatable manufacturing process.
The large volume of gas used in the metal powders atomizing process creates an opportunity to reduce costs and lower environmental footprint by capturing and recycling the gas back to the process. Reduced virgin gas requirements lower the energy needed to produce, package and distribute the gas. For metal powder atomizing, Nippon Sanso Matheson offers bulk argon and helium recycle systems, capable of reducing contaminants in recycled gas to single digit ppm (parts per million) level while achieving high recovery efficiency.
Powder Storage Cabinets to Keep your Powders Dry
Powder exposure to atmospheric air has a profound effect on additive manufacturing process variability and manufactured parts properties. Nippon Sanso Matheson’s expertise in the design and construction of powder storage cabinets is well known. Unlike conventional powder storage cabinets, Nippon Sanso Matheson cabinets store powder at tightly controlled environment to keep your powder dry and contaminant-free.
Post-Processing
Heat treating plays a key role in improving mechanical properties including the strength, durability, and performance of printed parts. Whatever your heat treating application and challenges are, Nippon Sanso Matheson heat treat experts can offer solutions and help you achieve stringent specifications while improving productivity.
Frequently Asked Questions
Metal additive manufacturing commonly uses high-purity or ultra-high-purity argon, nitrogen, helium, and application-specific gas mixtures. These gases are used in powder atomization, powder storage, build-chamber atmosphere control, printing, and post-processing.
Nippon Sanso Matheson supplies pure gases, ultra-high-purity gases, mixtures, specialty gas equipment, purification systems, recycling systems, powder-storage cabinets, automation support, and post-processing expertise (including heat treating and Hot Isostatic Pressing support) for metal additive manufacturing. Its solutions support processes from prototyping through production.
Argon provides an inert atmosphere that supports steps such as metal powder atomization, powder storage, build-chamber control, and printed-part processing. Nippon Sanso Matheson supplies high-purity and ultra-high-purity argon for additive manufacturing applications requiring controlled atmospheres.
Leaks, poor connections, cylinder changeouts, contaminated equipment, and inadequate purging can introduce impurities into the gas stream. Controlling these impurities supports repeatable processing and helps parts meet required mechanical, physical, and metallurgical properties.
Gas purification removes critical contaminants from pure gases and mixtures before they affect the manufacturing process. Nippon Sanso Matheson’s NANOCHEM® and Print Pure™ purifiers are designed to remove impurities to parts-per-billion levels for robust and repeatable additive manufacturing.
Yes. Metal powder atomization can use large volume of argon, creating an opportunity to capture, purify, and recycle argon. Nippon Sanso Matheson offers proprietary bulk argon and helium recycling systems able to achieve high recovery efficiency, as well as proprietary purification systems designed to reduce contaminants to single-digit parts-per-million levels.
Depending on the process, manufacturers may require specialty gas manifolds, automatic changeover systems, purification equipment, custom gas-delivery systems, and analytical equipment. Nippon Sanso Matheson designs and builds this equipment for additive manufacturing applications.
Metal powders should be protected from atmospheric air and moisture because exposure can increase process variability and affect finished-part properties. Nippon Sanso Matheson designs powder-storage cabinets with tightly controlled environments intended to keep powders dry and free from atmospheric contamination.
Yes. Its gas solutions support powder bed fusion, laser directed energy deposition, liquid metal jetting, wire-arc directed energy deposition, and other additive manufacturing processes. The appropriate gas, mixture, equipment, and purity level depend on the technology and material requirements.
Nippon Sanso Matheson combines gases, custom delivery systems, gas blending, purification, recycling, powder-storage solutions, robotic automation, fume removal, and heat-treating expertise. This broad capability supports additive manufacturers seeking repeatability, controlled gas quality, lower virgin-gas requirements, and scalable production.
