Nitrogen Generation for 3D Printing


Nitrogen is a critical substance in many industries for its ability to replace oxygen and prevent oxidation and combustion. Companies relying on 3D printing also depend heavily on nitrogen. With this gas being so critical to a 3D printer’s safety and function, many operations must order nitrogen in bulk. You have another option with Liberty Systems — nitrogen generation. 

Nitrogen’s Role in 3D Printing

3D printing creates a clean and professional final product with a laser that lays down layers of plastic, metal or composite materials. Oxygen can disrupt this process by causing sheets of oxidation to form. While oxidation can disrupt production, it can also lead to clumping in the power feed system that reduces the printer’s efficiency. Oxygen can also cause discoloration in the final product, affecting the professional look.

However, when nitrogen is added to a 3D printer, it displaces the oxygen and creates a completely inert environment that doesn’t interact with the laser or the material used to make the product. Nitrogen also removes the risk of combustion created by the dust that collects inside the printer.

Using a nitrogen generator from Liberty Systems, you can eliminate oxygen and improve the overall quality of all 3D-printed products. Manufacturers, laboratories and other industries that create custom products or prototypes with 3D printers can choose from our selection of Series M1 nitrogen generators that utilize your own compressed air source. We also offer the Series M3 — a generator with an included compressed air source. 

The Benefits of a Nitrogen Generator System for 3D Printing

With nitrogen’s critical role in the 3D printing process, operations need to keep the gas on-site. Most companies turn to bulk deliveries of liquid nitrogen, but nitrogen generators are a better approach. You save money on bulk orders and eliminate the need to wait for deliveries when you can produce nitrogen at any time. Without reliance on a third-party delivery, you don’t need to put your 3D printing process on hold.

The advantages of a nitrogen generator are clear, and with Liberty Systems, you can enjoy even more benefits:
