7 Important Ideas on Postprocessing in AM

Additive manufacturing is defined by 3D printing, but it is more than this step. For almost every AM production part, steps after the 3D printing operation are essential to complete the part and realize its value. Here are several thoughts.

6 Cutting Tools for Machining Made Via 3D Printing

By making tools, additive manufacturing aids so-called “subtractive” manufacturing (better known as machining). Here are examples of how 3D printing balances performance, coolant flow and weight in small and large cutting tools.
