3D Printing of PTFE
A new patent from 3M Deutschland GmbH, Neuss, Germany, makes it possible to process fully fluorinated polymers such as polytetrafluoroethylene (PTFE) by 3D printing. Together with its subsidiary Dyneon GmbH, 3M is driving advances in the additive manufacture of geometrically complex parts from prototypes to small-lot production. In the area of plastics fillers, spherical, hollow glass microspheres (3M Glass Bubbles) are being promoted. They are easy to process, thermally insulating, rapid-cooling or act as a white pigment, and reduce component weight significantly. They are already widely used in the automotive industry thanks to useful programs such as the "weight-volume calculator", which increase understanding of the filler and point up potential applications. In order to further optimize use of the filler in future, 3M has initiated a partner program to assist its customers in the best possible way with technical expertise and training in the use and processing of the filler.
