Refractory Metal Powders Are Expected to Become Raw Materials for 3D Printing

0 Comment

What is 3D printing? 3D printing is also known as additive manufacturing. Similar to the powder metallurgy processes we use today, metal devices manufactured with this technology are based on metal powders, such as ceramic powders and metal powders. The difference is that the powder is not sintered together, but formed by “printing” sections of […]
