Product Development Inc has been selling and supporting the Roland 3D milling machines for over 18 years. We have won multiple awards for both sales and service. Our staff is experienced, with Solidworks, Autocad, Rhino3D, Solidedge, Pro E. Our company started as a design firm/model shop using Solidworks and the Roland equipment to design and build products for our customers. We made a transition over 15 years ago to focus on selling the Roland solutions. We sell Roland machines to all companies, individuals, schools and universities in all 50 US states. We ask that you please consider us when making a purchasing decision, we have the knowledge and experience to make you successful.

SRP® (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.
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 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.
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.
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.
The 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.
Roland 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.
The 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.
The MDX-540’s Handy Panel and Virtual Control Panel simplify both setup and operation. The hand-held control panel can be extended from the machine, allowing you to operate the MDX-540 from a safe distance. It has a jog dial for changing spindle speed and selecting options on the menu. The Virtual Control Panel lets you control the MDX-540 directly from your PC.
Roland's international ISO certification is your quality assurance. Like all Roland products, the MDX-540 was designed and manufactured at a state-of-the-art, ISO-certified facility. Roland builds all products at its advanced Digital Factory one at a time by a single assembler – just like a Rolls Royce. Attention to detail is given the highest priority.
