3D printing of salt-like granular polyacrylamide as sacrificial molds for shaping versatile materials.

ABSTRACT: Digital light processing 3D printing is a powerful manufacturing technology for shaping materials into complex geometries with high resolution. However, the rheological and chemical requirements for printing limit the use of materials to photoactive resins. Here, we propose a versatile manufacturing platform for constructing versatile materials using DLP-printed water-soluble granular polyacrylamide as sacrificial molds. The polymerization-induced phase separation during printing results in a close packed granular geometry with intrinsic micropores, which greatly accelerates the dissolution rate of polyacrylamide. Combined with precise control over the molecular weight, this salt-like sacrificial mold can be fully dissolved in neutral water at room temperature within 30 min. Furthermore, s
