OverviewAnyway you look at it – the MDX-540 SRP® System is a winner. It’s one of the fastest and most accurate RP systems on the market. And its price tag is less than half most additive systems. The desktop device comes complete with powerful CAM software, making it easy to quickly produce everything from functional and snap-fit prototypes to light metal molds and custom jewelry.
     Summary
Features
SRP® TechnologySRP® (Subtractive Rapid Prototyping) - starting with a solid object and removing unwanted material - has several advantages over traditional additive rapid prototyping. SRP devices cost significantly less while producing prototypes out of a wider variety of non-proprietary materials with greater precision and better surface finish.
Functional Prototypes
Powered by a 400W spindle, the MDX-540 mills a wide variety of nonproprietary materials and popular engineered plastics such as ABS, Delrin, and nylon.Compared to additive RP systems, the desktop device produces functional prototypes that are better for structural, thermal, and electrical testing.Plus, MDX-540 parts meet a host of FDA and other government regulations. The MDX-540 functional prototypes 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. The MDX-540 can also mill non-ferrous prototypes and molds made of aluminum, brass and copper. This lets design engineers create metal molds for rapid injection molding and EDM electrodes for production tooling. Bundled Software
Bundled SRP Player CAM software automates the prototyping process and generates tool paths with high speed and precision. The user-friendly, wizard-based program offers uniform 3D scaling, support for 4-axis milling, and simulation of finished 3D parts. It lets engineers quickly review the simulated prototype on the monitor and send it to the MDX-540 for production. The end result is faster prototype production, tighter dimensional accuracies and a silky smooth surface finish. Rotary Axis (Optional)With the optional rotary axis, the MDX-540 produces parts with even greater speed and accuracy. When one side is completed, the part is automatically rotated until all four sides have been milled. This saves engineers the time and reduces errors associated with rotating objects by hand. Automatic Tool Changer (Optional)
The Roland Automatic Tool Changer (ATC) further reduces the time and cost associated with product development. From roughing to finishing, this optional accessory enables the MDX-540 to mill prototypes completely unattended. It automatically changes up to four preset tools of different sizes. The ATC comes with an air-activated, high-precision spindle. High PrecisionThe MDX-540’s hi-precision spindle decreases vibration within the unit and produces extremely accurate models, ideal for complex snap-fits. With ISO15448 standard collets, the MDX-540 also generates a smooth surface finish that requires little to no post finishing work. Speedy ProductionRoland SRP devices can mill parts in an average time of just over four hours. 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. Office ReadyThe MDX-540's emergency stop switch enables you to shut down the machine at the push of a button, making it safe to operate in any office environment. An optional safety cover makes the cutting mechanism inaccessible during operation and reduces dust in the surrounding environment. The MDX-540 is also compact enough to fit though standard-sized doors and roll from one room to the next.
