Roland MDX-40A

Benchtop Mill - Roland MDX-40A

The Roland MDX-40A CNC machine combines the advanced capabilities of a Subtractive Rapid Prototyping® (SRP) system with the ease-of-use of a benchtop CNC mill to provide product engineers and designers with a powerful 3D milling device. Offered at less than half the cost of additive systems, MDX-40A CNC mill produces affordable and highly accurate prototypes from a wide variety of non-proprietary materials with greater precision and excellent surface finish. Unlike other CNC machines used for rapid prototyping, the compact design of the MDX-40A is the perfect fit for any office and classroom space. It can even function as a CNC engraving machine.


  • Subtractive Rapid Prototyping (SRP) Technology
    Subtractive Rapid Prototyping (SRP) has several advantages over additive rapid prototyping (RP) systems, also called “3D printing.” SRP devices cost significantly less to own and operate, resulting in lower material costs and no annual maintenance contracts, while producing prototypes out of a wider variety of non-proprietary materials with greater precision and better surface finish.
  • SRP Systems
    Todd Grimm, the man who wrote the book on rapid prototyping for the Society of Manufacturing Engineers, found that Roland SRP devices produce prototypes faster, better and cheaper than most additive RP systems.
  • Functional Prototypes
    Like all Roland CNC engraving machines and mills, the MDX-40A benchtop CNC mill produces a wide range of low-cost, non-proprietary materials typically used for rapid prototyping, including ABS, delrin, nylon, acrylic and tooling board. This lets designers and engineers create functional prototypes to test how well products will actually work. Handled by market focus groups, these prototypes must perform like the final manufactured product and survive a barrage of physical tests, including thermal and structural trials. For example, toothbrush prototypes undergo in-vivo testing for hand fit, brush reach and handle deflection.
  • High Precision
    The MDX-40A benchtop CNC mill is equipped with a high-precision spindle that decreases vibration within the unit and produces extremely accurate models. It achieves resolutions up to 0.000039 inches per step and creates the most accurate prototypes for complex snap-fits. With ISO15448 standard collets, the MDX-40A CNC mill also generates a smooth surface finish that requires little to no post finishing work.
  • Speedy Production
    Roland RP systems, like the MDX-40A, typically create parts faster than a 3D printer does. According to Todd Grimm’s independent study of RP systems, the SRP process saves time by producing parts that are smooth and precise right off the machine. Additive systems, on the other hand, typically require time-consuming post finishing processes.
  • SRP Player CAM Software
    The MDX-40A benchtop CNC mill is packaged with Roland SRP Player CAM software, ideal for rapid prototyping and custom rapid manufacturing applications. SRP Player was created specifically for designers and engineers to make SRP prototype parts quickly using an easy five-step process and intuitive workflow. SRP Player accepts a wide range of file formats, including industry standard .STL. As a result, it produces superior parts with smooth surfaces and accurate, tight-fit precision.
  • ClickMill Software
    Bundled ClickMill software enables direct control of the MDX-40A for surfacing, drilling holes, cutting pockets and other finishing processes, all without accessing CAD or CAM software.
  • G-Code Support
    The MDX-40 CNC mill is designed to fit nicely into any office environment. It comes with an emergency stop switch that shuts down the machine at the push of a button. An optional safety cover makes the cutting mechanism inaccessible during operation and keeps dust out of the surrounding environment.
  • Rotary Axis (Optional)
    With the ZCL-40A optional rotary axis, the MDX-40A performs unattended four-sided milling at increments of one degree. When one side is completed, the part is automatically rotated until all sides have been milled. This saves time and lets you continue on with your design work while your prototypes are being created.

    The ZCL-40A optional rotary axis unit supports materials up to 10.6” long by 4.7” in diameter (270mm long by 120mm in diameter), twice the capacity of Roland’s previous model and large enough to mill a 16.9oz. (500ml) PET bottle.

  • Optional Contact Scanning Unit
    The optional ZSC-1 adds the power of reverse engineering to the MDX-40A. Using Roland Active Piezo Sensor technology, the MDX-40A transforms into a powerful and accurate tool for digitizing an existing part or mold for your CAD software. This technology gives the MDX-40A the ability to scan a wide variety of objects including soft objects like modeling clay. It can even scan glass or acrylic objects without making a scratch. The ZSC-1 includes scanning software – or for more advanced reverse engineering projects you can add a copy of PixForm Pro 2 reverse engineering software.
  • Perfect Office Fit
    The MDX-40A is a compact desktop mill that fits nicely in any office. It comes with an emergency stop switch that shuts down the machine at the push of a button. An integrated safety cover makes the cutting mechanism inaccessible during operation and keeps dust out of the surrounding environment.
