Sustainable 3D Printing Breakthrough: Researchers Synthesize Monofunctional Photopolymerizable Monomer

Strategic Insights -

Investigations into 3D printing have led to the discovery of a novel monofunctional photopolymerizable monomer, glycerol carbonate methyl itaconate (GCI), which can significantly enhance the sustainability of fossil-based resins and impart added functionality. Researchers at the University of Bologna have synthesized and chemically characterized GCI, demonstrating its compatibility and increasing the biobased content of resins up to 77 wt %. Mechanical testing revealed that GCI improves the rigidity of soft resins while enhancing the elongation properties of rigid formulations. This breakthrough has significant implications for the potential applications of itaconic acid-derived monomers in sustainable 3D printing.

Key Takeaways:
