Troy, Michigan – March 4, 2009 – ProMetal RCT, LLC, an Ex One Company, has become the latest Technology Partner in the DiMora Motorcar program to develop the $2 million Natalia SLS 2 sport luxury sedan. An integrated product and process team will use the ProMetal digital 3D printing technology to produce castings for the 1200-horsepower Volcano V16 engine without the need for patterns or tooling.
Rapid Casting Technology (RCT) is a generative or additive process. The ProMetal RCT? equipment automatically builds sand molds and cores for casting metal directly from CAD data. Standard foundry industry materials are used, enabling easy integration of the new equipment into existing manufacturing and foundry procedures. The large building volume and high building rate combine to make patternless production a reality for metal-based prototype castings and low volume production. The molds and cores are built in an additive layer-wise fashion using a printhead, analogous to the ink-jet technology commonly used in desktop printers.
According to Dan Maas, Director of Business Development for ProMetal, “This revolutionary ProMetal RCT process allows design freedoms, heretofore never available to the casting designer or the foundry. Removing the requirements for parting lines, draft angles and providing undercuts is just the tip of the iceberg,” asserted Maas. “Providing nested cores, spiral vents, volute shapes, integration of multiple components, in-situ cores, and unique rigging geometry to minimize turbulence are design features that are being utilized today by advanced companies.”
Ex One Vice President Dr. Howard Kuhn has noted that today’s high-technology workforce is well prepared to take advantage of the capabilities made available through digital manufacturing. “The modern generation’s love affair with digital products positions them for a comfortable transition to, and enthusiastic attraction toward, digital work in manufacturing--through both virtual simulations and exciting production tools, such as ProMetal’s Rapid Casting Technology.”
“The stringent specifications of the DiMora Volcano V16 engine give us an excellent opportunity to demonstrate what RCT allows the engine designer and manufacturer to accomplish,” said Maas. “There is no room for error when building an exotic, lightweight aluminum engine that produces 1200 horsepower.”
DiMora Motorcar Founder Alfred DiMora pointed out the advantages that most impressed him about the ProMetal process. “This technology is at the forefront of digital additive manufacturing for the production of complex 3D shapes. During the design process, being able to accomplish in a few hours what used to take days allows you to refine your design through additional iterations. Eliminating patterns and tooling saves time and reduces waste, making the entire process faster, cheaper, and greener, while producing a final product that is superior in every way. The Volcano V16 will be an unmatched engine thanks to the engineering skills and technology of ProMetal RCT.”

About DiMora Motorcar
Based in Palm Springs, California, DiMora Motorcar crafts automobiles designed to exceed expectations for safety, performance, technology, ecology, beauty, comfort, and luxury. We are the first to reveal the design, production, and testing of our automobiles via the Internet so that people around the world can learn about--and participate in--the process.
The founder, CEO, and driving force behind DiMora Motorcar, Alfred J. DiMora, produced two of America's finest luxury automobiles, the Clenet (as owner) and the Sceptre (as co-founder). When President Reagan declared 1986 the Centennial Year of the Gasoline-Powered Automobile, Mr. DiMora's Clenet was selected as the Official Centennial Car. As a result, he and the Clenet were honored at the Automotive Hall of Fame in Michigan. He also founded Starbridge Systems, Inc., where he developed the FPGA supercomputer. Using his technological and automotive backgrounds, Alfred DiMora blends the two worlds together to create this new experience in automotive history, the Natalia SLS 2.
