Fast prototyping has been a critical factor to reduce the time of development. The company used to have a couple of suppliers for 3D printing, but they needed more efficiency. They design products and molds internally, so the opportunity to have a real piece even in an early stage is beneficial. In the past, they would have to manually modify the pieces to simulate the modification, but it was not possible in some case. If in a hurry, they would modify the molds step by step until reaching the final result.
