As the most precursor and the most potential technology in the whole 3D printing technology, metal 3D printing technology is an important development direction of modern manufacturing technology. Metal 3D printing equipment usually has a closed reaction chamber, which can not only prevent the leakage of some toxic and harmful by-products after being filled with inert gas, but also prevent the metal powder from oxidizing in the high temperature of the laser, reducing the strength and ductility of the printed object.
Nitrogen and argon are both inert gases, and because nitrogen is the most economical and readily available, nitrogen is the best gas solution for metal 3D printing. The nitrogen generator provides reliable high-purity nitrogen for metal 3D printing technology, and the pressure swing adsorption nitrogen generator adopts the principle of pressure swing adsorption (PSA), which can effectively remove oxygen, water and other impurities in the compressed air by using the adsorption and desorption of oxygen molecules by carbon molecular sieve (CMS) to ensure that it can provide high purity (nitrogen purity 95% to 99.).999%), uninterrupted nitrogen. It is compact and compact, and can be integrated with 3D printing equipment to provide safe, reliable, energy-efficient, and low-cost high-purity nitrogen. Due to the advantages of easy operation and simple maintenance, the nitrogen generator is widely used in various fields, including shielding gas for metal 3D printing.
Metal 3D printing has a wide range of applications, such as biomedical, dentistry, artificial bones, aerospace, automotive manufacturing, etc.
The use of nitrogen in 3D printing offers multiple advantages:
It improves print quality by preventing oxidation, resulting in stronger, more durable components. This is especially important when printing with metal, as oxidation can significantly affect the mechanical properties of the final product.
Nitrogen can improve the surface finish of 3D printed parts. In the absence of oxygen, the material melts more evenly, resulting in a smoother, finer surface. This reduces the need for follow-up processing, saving time and resources.
The use of nitrogen expands the range of materials that can be printed. Some materials are highly reactive and cannot be printed in oxygen-rich environments. By using nitrogen, these materials become viable, opening up new possibilities for 3D printing products.
