it is not possible to create a true scale model using common techniques involving cardboard and laser cutting machines. ”I need a technology that is rapid and easy,” he said. “Time compression is very important. The Objet printer is easy to operate like a common office printer, and the software does not require any special skill. It prints very quickly, so we can rapidly move from concept to reality and create additional prototypes after modifying the design.” This enables him to get instant feedback from his advisors, thus reducing the entire design and research process.
