3D printing of composition-controlled copolymers

摘要

Computer-controlled methods for forming composition-controlled products using 3D printing include placing at least two liquid reaction compositions in at least two respective reservoirs; And mixing the two or more liquid reaction compositions, wherein the mixing step in turn comprises controlling, by a computer, the mass ratio of the two or more liquid reaction compositions mixed. The computer-controlled method includes, under the control of a computer, scanning a substrate with a mixed liquid reactant nozzle; Depositing a mixed liquid reaction composition onto a substrate; And operating a light source to polymerize the deposited mixed liquid reaction composition under the control of a computer.
