Zhejiang University Researchers Potentially Develop Sustainable Closed Loop Resins

Zhejiang University researchers have developed a sustainable resin that can be reused multiple times through a reversible photo-click reaction. This breakthrough could lead to significant cost and waste reductions in 3D printing materials. The research team created dithioacetal bonds that can be associated and disassociated, allowing for the separation of resin into its original materials for reuse. The potential recyclability of these materials could make 3D printing, especially vat polymerization, more sustainable and cost-effective. However, there are still uncertainties regarding the costs, safety, and implementation of this chemistry in practical applications.
