Additive or Subtractive Prototyping: Which is Best?

The day has finally come. Your new component design has been approved and now it’s time to take it to prototype. But what manufacturing process should you choose?

Subtractive or additive (3D printing) are the two distinctive prototyping and manufacturing methods that are constantly being compared and evaluated.

As companies seek solutions that provide better, faster, more cost-effective ways to produce prototypes and manufacture parts, they find that both technologies have benefits and drawbacks, depending on the application and business criteria.

This e-book from Protomatic — a precision CNC machine shop specializing in prototypes and custom short-run production — explores the pluses and minuses and helps you decide which process is best for you.
