Key Takeaways
- Heidelberg University has created a metastable resin that depolymerises in seconds when exposed to a catalyst, enabling true chemical recycling for SLA/DLP prints.
- Spectroscopic testing shows the reclaimed resin is 100 % chemically identical to the virgin material, preserving resolution and mechanical properties.
- The Institute of Engineering and Rural Technology (IERT) demonstrates a 30 % cost reduction by converting post-consumer PET bottles into FFF filament with comparable tensile strength (≈ 45 MPa) to commercial PETG.
- Both breakthroughs move additive manufacturing toward a circular-economy model without sacrificing part quality or speed.
