Revolutionizing the Injection Molding Process Using 3D Printing

3D printing has turned the production of injection molded prototypes into a quick, easy and inexpensive process. See how PolyJet 3D Printing technology from Stratasys helps a team at Budapest University create an injection mold for functional testing at reduced time and cost.


Commissioned to produce a fan that provides enhanced engine cooling and reduced noise, Dr. Jozsef Gabor Kovács, Department of Polymer Engineering, Budapest University of Technology and Economics, and his team needed to find an efficient, inexpensive method of producing injection molded prototypes to test the fan in the end-product material. The design and development process involved subjecting the fan to extreme functional tests on a tight deadline, so the team had to produce iterations extremely quickly.


Conventional methods of producing molds, such as CNC manufacturing with steel, are expensive and time-consuming. So Kovács took the innovative approach of using the PolyJet-based Objet Connex 3D printer to produce the injection molds.
