ProtoCAM does most of its prototyping work using additive rapid prototyping technologies such as stereolithography (SLA), selective laser sintering (SLS) and 3D printing. Fused deposition modeling (FDM) is another additive rapid prototyping process that is used. With additive rapid prototyping, material is added on or built up in the creation process.

Subtractive prototyping is another way to create prototypes in which material is removed from a larger piece of material. Subtractive prototypes are typically created using more traditional manufacturing processes. These include standard machining process such as milling, turning/lathing or drilling, and more modern tools like CNC machining. So with subtractive prototyping, you might start with a block of metal or plastic and cut away material until the prototype part is created.

In rapid prototyping, there are advantages and disadvantages to any choice of technology. Subtractive prototyping is limited to relatively simple shapes - complex geometries are not possible. The material must be readily available in the size and shape needed. And subtractive RP usually takes longer. Its main advantage is that is made in the final production material.

So if time, design complexities and materials are critical, additive rapid prototyping is likely the best choice. Contact ProtoCAM for additive rapid prototyping services.
