Nontoxic 'light-activated' compound shows promise for safer 3D printing of advanced biomaterials
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a new class of light-activated compounds that could lead to safer and more versatile applications in 3D printing, cosmetics and medicine.
Scientists from Nanyang Technological University, Singapore have created a new class of light-activated compounds that could revolutionize 3D printing with safer, non-toxic materials. These aryl diazirine photoinitiators, published in NPG Asia Materials, are nontoxic to human cells and offer superior performance compared to current industry standards.
The study demonstrates the compounds' ability to reduce material shrinkage and compatibility with water-based sustainable resins. Unlike traditional photoinitiators like TPO and BAPO, which are banned in certain regions due to reproductive toxicity, these new compounds are safe, biocompatible, and even water-soluble. This breakthrough could lead to more advanced manufacturing, biomaterials, and wearable electronics while addressing environmental concerns.
