liquid polymer
3D printing process using shining light.
As specified by Chung Sun, associate professor of mechanical engineering at the McCormick School of Engineering, “The 3D printing process is no longer a way to merely make a replica of the designed model. We are using light to do the manufacturing. Shining light on the liquid polymer causes it to crosslink, or polymerize, converting the liquid to a solid. This contributes to the speed and precision of our 3D printing process — two major challenges that conventional 3D printing is facing.”
