Vacuum furnaces for 3D Printing

What is industrial 3D printing?

Originally introduced in 1980, additive manufacturing, more commonly known today as 3D printing, continues to grow in popularity and adoption across industries. Mostly a subtractive process, the manufacturing process wastes the raw materials then reuse them. For example, a car factory cuts sheet metal then shapes into specific body parts. Leftover metal is then melted down and formed into metal plates. As metal plates, the leftover metal can then be reused for any further processes.

In contrast, 3D printing is a very precise manufacturing process. Manufacturing with 3D printing effectively uses raw materials and requires no cutting down, no leftover material, and no need to reprocess the materials. Therefore, it’s only an additive process and not subtractive. Manufacturers reduce material waste, as well as processing time and required equipment with 3D printing.

3D printing process and vacuum heat treating

Additive manufactured parts tend to use net shapes and complex geometries. Unique shapes make them impossible to machine and remove very little material during downstream processing. Therefore, the finished parts must never exhibit decarburization or contaminated surfaces from subsequent thermal processing. A well-maintained vacuum furnace with precise temperature controls is critical within the additive manufacturing world. These industrial furnaces operate totally devoid of oxygen by being equipped with diffusion pumps. This function makes it possible to attain deep vacuum levels.
