Subtractive Manufacturing vs Additive Manufacturing:    How to Select?

What Is Subtractive Manufacturing?

Subtractive manufacturing, including computer    numerical control (CNC) machining, essentially    involves subtracting or cutting material from    a solid block to create an end product.

With many different forms, including milling,    turning, laser cutting, wire EDM, and carving,    subtractive manufacturing is used for a wide    variety of prototyping, production, and    assembly line applications.

What Is Additive Manufacturing?

Additive manufacturing (3D printing) is a    newer fabrication process. With its speed,    flexibility, and cost advantages, 3D printing    has become commonplace in modern product    development and prototyping.

Unlike subtractive manufacturing, additive    manufacturing (AM) deposits materials only    where necessary on the build platform,    typically building parts layer by layer.

Additive manufacturing includes a variety    of technologies, such as FFF, SLA, DLP,    and MJF, and is capable of processing a    wide range of polymer and metal materials.

Subtractive vs Additive Manufacturing:    Which Process Should You Choose?

Both technologies have their strengths and    weaknesses when it comes to product    development and the manufacturing environment.

Subtractive manufacturing creates parts by    removing material from a solid block, while    additive manufacturing builds parts by    depositing material layer by layer.

Choosing the appropriate manufacturing    process depends on the specific requirements    of your product design and development project.
