TU Wien develops method by which tailored, tough polymers can be made at high resolution for 3D printing

The Technical University of Vienna (TU Wien) in Austria has developed a new approach for high-resolution 3D printing of tailored, homogenously crosslinked, tough, methacrylate-based photopolymers.

Many coatings, including tooth fillings, varnishes and printing inks, are cured with light, but homogenous, tailored, polymer networks cannot be produced. Even if you manage it, the materials tend to be brittle, which limits the ability to use photopolymers for applications such as 3D printing, biomedicine, and microelectronics.

In the journal Angewandte Chemie, researchers published a paper titled “Vinyl Sulfonate Esters: Efficient Chain Transfer Agents for the 3D Printing of Tough Photopolymers without Retardation,” which explains a method by which methacrylate-based, homogenously crosslinked, tailored, tough polymers can be made – even at high resolution for 3D printing.
