Oxygen Exclusion: Nitrogen is an inert gas that contains very low levels of oxygen. In SLS 3D printing, minimizing the presence of oxygen within the printing chamber is crucial. Oxygen can react with and degrade certain SLS materials, leading to poor print quality and undesirable defects in the final printed parts. By using nitrogen to displace oxygen, you create a controlled and oxygen-free printing environment, reducing the risk of oxidation. Improved Print Quality: The absence of oxygen in the printing chamber helps maintain the integrity of the SLS material being used. This results in superior print quality with smoother surface finishes, increased part accuracy, and enhanced mechanical properties. Nitrogen assists in achieving the desired aesthetic and functional characteristics in your 3D-printed parts. Reduced Defects: Oxygen exposure during the SLS printing process can cause issues like warping, discoloration, and incomplete fusion of powder particles. Nitrogen minimizes these defects, leading to more reliable and consistent printing outcomes. Fewer defects mean less material waste and increased production efficiency.
