Heart pump from a 3D printer
According to ETH doctoral student Kai von Petersdorff-Campen,“ My goal was not to make a good heart pump, but to demonstrate the principle of how it can be produced in a single step.
Conventional manufacturing methods are the bottleneck in the development of ventricular assist devices (VADs). The shift to agile, fast and test-driven development practices renders the use of additive manufacturing techniques necessary. A critical component of heart pumps are magnets, e.g. in the driving and bearing system of the impellers in turbodynamic VADs. We have developed a method to 3D print magnets directly into parts by fused deposition modeling. Using that method we printed and tested a functional pump with 10 integrated components”.
