| Résumé : |
Is there a quantum leap on the horizon for 3D printing? The prototype of a newly developed 3D printer is able to process commercial pellets – also those of high-performance plastics such as PEEK, PPS, PSU, PA and PC, with or without fibers. The machine applies the usual strand-deposition process, though with a simply designed print head that includes a radial screw. |

- FIGURES : 1. The prototype of the 3D printer, which is able to process commercial pellets. Inert gas prevents oxidation of the plastic melt - 2. Attached to a disk, the spiral drives the plastic from the outside to the inside, towards the nozzle outlet. A force acting upon the disk from above controls the pressure between disk and the opposite area where the outlet is, and therefore the plastic extrusion process itself |
