Energy- and resource-efficient additive manufacturing with recycled plastics - Pellet-3D

3D printers are increasingly being used in production. There is a high demand for processes to increase recycling rates while maintaining the highest possible product quality. Especially in industrial use, process time plays a crucial role.

The reprocessing of 3D printing waste (e.g. misprints or support structures) into filaments and their reuse has already been demonstrated. The use of a pellet printer should accelerate this recycling process. In this process, the printing waste is melted down and directly reprinted, eliminating the process step of filament production. Direct processing of the recycled material improves the energy efficiency of the overall process and shortens the process time.  The use of larger nozzle diameters in the pellet printer further accelerates the printing process.

Industry partners provide support in preparing the plastic waste to the optimum particle size distribution and shape, as well as in material processing.
