Cooling for Additive Manufacturing
Expert solutions to help you succeed
Temperature and the ability to cool parts rapidly play a decisive role in the manufacturing process. Air Products offers gas solutions for cooling and the dissipation of heat during the 3D printing process.
Nitrogen, argon and helium can all be used. The minimum cooling rate requirement is the key factor in determining which gas is used. Helium is used when high cooling rates are desired. Cooling rates can also be increased with higher gas pressure and velocity.
In addition, Air Products offers a patented liquid nitrogen-based cooling technology for a wide variety of applications. Our system provides tight temperature control and precise flowrates for targeted cooling of metals, non-metals and composites.
Our Air Products technical team has extensive applications knowledge in surface/bulk treatment of metals to help additive manufacturers optimize the gas selection, supply mode, and purity for improved part processing.

“How does gas affect the quality of my additive manufacturing process?”
As with other traditional methods of prototyping and manufacturing metal parts, the proper gas atmosphere is critical for producing quality products. Nitrogen and argon are commonly used to provide inert atmospheres during additive manufacturing. It is important to use the correct flow rate and purge duration to avoid deformed parts and ensure a safe production environment. For example, high oxygen content in the atmosphere will result in oxidation of the powder metal leading to poor part quality, clumping in the powder feed, or high porosity in the end product. It will also reduce the amount of recyclable powder for future use. Inerting is also critical for proper management of the combustible dust arising from the powder metal and printing process. Post treatments after printing may require industrial gases, depending on the application.

CryoEase® Microbulk Solutions
CryoEase® microbulk technology is a modern concept where your gas is supplied by filling on-site vs. the traditional method for smaller volume usage, where gas is supplied by swapping full for empty cylinders and dewars. CryoEase® microbulk supply features specially designed trucks with integrated controls and flexible storage tank options. End usage can be provided as pure gases, cryogenic liquids or gaseous mixtures via a blender installed at your site.
