Dual Light Technique Creates Complex Resin 3D Structures

Jan-14-19 An innovative liquid resin 3D-printing technique produces complex structures much faster than conventional methods.

Developed by a team from the University of Michigan, the method relies on using a pair of lights to determine the areas of the resin that remains fluid or hardens. The new technique eliminates previous issues with the resin solidifying on the laser’s window—which was previously solved using oxygen that in turn required very ‘runny’ resin that could not form complex shapes. By replacing the oxygen method with a second light, the 3D printer can create complex structures 100 times faster than previous techniques.
