When Dr. Jozsef Gabor Kovács at Budapest University was commissioned to develop a fan the improved engine cooling and reduce noise he needed to make production representative prototypes for testing. A Stratasys Objet500 Connex 3D printer was used to create a simple tool made from their digital ABS photopolymer. It took 22 hours to print the three-piece tool. The rapid …
