Stratasys has released SAF ReLife, a software-based technology for repurposing waste PA12 powder from additive manufacturing processes into high-quality parts. By reusing waste powder from powder bed fusion in its H350 3D printer, SAF ReLife becomes transformative for sustainability in 3D printing.
The company promises SAF ReLife will “significantly lower the cost-per-part” and reduce the carbon footprint per build. Spanish service bureau Wehl Green was granted early access to the platform to test innovation, and it has already reported a 20% cut in total cost per part and noticeably lower waste, with a rapid turnaround of 48 hours.
An independent Life Cycle Assessment (LCA) by Fraunhofer IPA confirms that repurposing PA12 waste for SAF technology can reduce the carbon footprint by up to 89% compared to standard PA12 production. “SAF ReLife gives customers a unique ability to make high-quality parts from powder waste,” said Neil Hopkinson, VP of Additive Manufacturing Technology at Stratasys.
Javier García, Co-founder of Wehl Green, called SAF ReLife “a game-changer” for competitiveness, adding that it supports a circular economy while maintaining industrial-grade quality. Fraunhofer’s assessment notes that Stratasys’ SAF ReLife solution can cut the carbon footprint by 43% with conventional energy and by 89% with renewables.
