Benchtop mills used for subtractive rapid protopying

Roland DGA Corp. offers a series of benchtop milling machines designed for tasks ranging from SRP (subtractive rapid prototyping) to manufacturing dental prosthetics and jewelry.

The company’s MDX-540, for example, is a 4-axis CNC intended for SRP. It comes with a 400W, DC brushless motor, user-friendly software and a handheld control panel that reportedly allows quick, easy setups. Maximum work envelope is 19.6” x 15.7” by 6.1” without rotary axis. Prices range from $21,000 to $37,000.

According to Roland, SRP offers numerous advantages over additive prototyping processes, including faster speed, better finishes and the ability to process more types of materials.
