In the past 2015, sales of metal 3D printers have shown significant growth. After repeated thoughts and analysis, Xiaobian believes that the main reason behind this is that the aerospace, automotive and medical industries have already recognized the advantages of metal 3D printing , and began to gradually adopt this technology in actual manufacturing. However, the metal powder materials required for this technology still need to be further developed to meet the growing demand.
So far, there are many companies producing metal powder materials worldwide, but one of them is very special. It is just established in 2015 and is headquartered in Equispheres, Ottawa, Canada. The company has attracted the attention of China's 3D printing network because they have developed a new type of atomization reactor. The device produces spherical metal powders with high performance and consistency, helping metal 3D printing and jetting applications become more precise and easier to control. Equispheres has now patented this atomization technology and plans to bring metal powder materials manufactured by the technology to market in the first quarter of 2016.
Most of the current metal powder materials are manufactured by a dual gas flow atomization process, and there are generally some inherent problems that may cause defects in the final 3D printed metal object. For example, the shape of the powder is irregular; the dimensional uniformity is poor; sometimes it condenses into larger agglomerates; the denseness is poor. When using this powder to make high-value metal parts, such as rocket engine parts, any of the above-mentioned defects are likely to cause a drop in accuracy, which in turn affects the overall mechanical properties of the part.
However, Equispheres' new atomization technology claims to have no such problems. It is understood that the metal powder produced by this technology is called "free flowing, uniform and uniform, no agglomeration", with better controllability and fluidity, can improve metal 3D printing and cold spray manufacturing (metal particles through compressed air) The efficiency of the two types of processes is accelerated to supersonic speed and then directly impacts the physical deformation of the surface of the object to achieve a firm attachment.
“With the successful commissioning of our first commercial atomization reactor, we have proven that our technology can indeed produce better quality metal powders than similar products on the market today,†said Kevin Nicholds, CEO and President of Equispheres. This will enable us to better meet the manufacturing needs of aerospace and other industries."
According to Equispheres' plan, the commercialization phase of this atomization technology will last for 90 days. After that, they will begin mass production and provide high quality spherical metal powder materials for partners in the aerospace industry. In Xiaobian's view, the company's new atomization technology will undoubtedly greatly promote the development of the metal powder material industry, which will drive the entire metal 3D printing industry to move forward faster. Perhaps in 2016, this field will usher in a new leap.
