“Success of Mechnano and Tethon3D’s ESD Resin: Passing NASA’s Outgassing Tests”


Mechnano and Tethon3D have disclosed that their C-Lite vat photopolymerization resin has successfully passed outgassing tests set by NASA, under the ASTM E595-77/84/90 requirements. The Electrostatic Discharge (ESD) material, with resistance to high-temperature, is compatible with Stereolithography (SLA), Digital Light Processing (DLP), and Liquid Crystal Polymer (LCP) 3D printer systems. C-Lite can withstand heat up to 225 degrees Celsius, making it suitable for high-temperature applications.

The release of gases by non-metallic materials under heat or vacuum, also known as outgassing, poses a major challenge in the manufacturing process. This can lead to the contamination and functional impairment of components. The exemplary test results of C-Lite, which included Total Mass Loss (TML) at 0.7%, Collected Volatile Condensable Material (CVCM) at 0.02%, and water vapor recovery at 0.13%, marked it as a non-outgassing material. This emphasizing on C-Lite’s potential use in industries like electronics and optics, where high-temperature and low-pressure conditions are prevalent.

Dr. Olga Ivanova, the Director of Applications and Technology at Mechnano, highlighted C-Lite’s static-dissipative and thermal properties. These make it optimal for use in electronic applications, including space equipment and medical devices. Trent Allen, CEO of Tethon3D, pointed out the potential use of carbon nanotube (CNT) photopolymer materials in worldwide additive manufacturing.

C-Lite’s robust thermal properties and compatibility with various AM systems make it a flexible selection for challenging environments. As we look to the future, we may observe more widespread applications and advancements in high-performance materials across the space, electronics, and medical sectors.
