The MDX-650 benchtop SRP (Subtractive Rapid Prototyping) device lets engineers and designers mill 3D prototypes quickly and inexpensively. With its optional rotary axis, the MDX-650 becomes a 4-axis machine capable of milling all four sides of an object. The MDX-650 produces hi-quality molds in just a few hours. In addition to saving time and money, the MDX-650 lets engineers keep proprietary secrets in-house.
