If you need to transform a design from concept to reality, what’s the best way to approach your project? Many businesses are torn between two options: CNC prototyping, also referred to as subtractive manufacturing, and 3D printing, also known as additive manufacturing. Here is what you need to know about both processes and why you might want to choose one over the other for your next project. 

What is CNC Prototyping?

CNC prototyping is also known as subtractive manufacturing. This is a process in which 3D objects are created by removing unneeded material from a larger piece. The source material could be something like solid wood, acrylic, PVC, solid surface, or aluminum. 

You can think of CNC prototyping as being similar to high-tech sculpture work. The company will start with a large piece of material and have the desired result programmed into a specialized piece of software. 

The finished piece in subtractive manufacturing is made from a single, sold composition instead of a composite of multiple pieces or layers. This creates something that has high durability, structural integrity, and accuracy according to the project specs. 

What is 3D Printing?

Also referred to as additive manufacturing, 3D printing is a process in which three-dimensional parts are created from materials like liquid resin. This is a relatively new process that might be useful for prototypes, but it isn’t affordable or fast enough to make it a viable option. 

Why Choose CNC Prototyping vs. 3D Printing

If you’re torn between CNC vs. 3D printing, it’s helpful to understand how one can benefit your project over the other. For example, CNC prototyping is inherently simpler and easier to modify than 3D printing, which is excellent if your prototype is a success. Here are a few of the other reasons why you should choose CNC prototyping over 3D printing for your project:

  • Accurate, fast results – CNC prototypes have become incredibly accurate and precise, meaning your project will meet the strict specifications you outline. CNC machines can also produce parts quickly, so you can get fast results. 
  • Cost-effective – CNC machining isn’t new, and the companies that provide the services have perfected their approach. You’ll get a cost-effective solution that doesn’t sacrifice quality. 
  • Simple to modify – Because your design is programmed into and controlled by a computer, it is simple to modify if needed. Even better, you can scale production if your prototype design is successful.
