The world of 3D printing has grown significantly over the years, and with that, so has the waste generated from the hobby. Thankfully, we have researchers like the team of scientists over at Zhejiang University who are working hard to reduce this waste and make 3D printing more sustainable as a whole. The team is directed by Professor Xie Tao and Professor Zheng Ning, who led the group in developing a 3D printing resin that can be recycled over and over again.
The team elaborated on the process, explaining that the resin is more easily recyclable thanks to what they call a thermally reversible photo-click reaction. This makes the resin infinitely recyclable as the molecular structure can be rebuilt each time as if the material were new. This lends to their ultimate goal of helping reduce resin waste when UV printing.
