Sustainability – Next Generation
Our circular economy project: reconditioning powder waste for 3D printing.
In the additive manufacturing process with powder-based polymers (PBF-LB, PBF-IR), significant amounts of powder waste, especially from polyamides, are generated. Although optimized powder management can reduce this waste, it cannot be completely eliminated, which makes it a sustainability issue. Therefore, DG is currently developing methods in its R&D department to recondition this powder waste and make it reusable in the manufacturing process.
If the powders can no longer be adequately reconditioned for additive manufacturing, they are to be repurposed according to the Zero Waste concept. This includes regranulating the powders for injection molding or using them as blasting powder for post-processing in additive manufacturing.
