The molecular design of photo-curable and high-strength benzoxazine for 3D printing.

Low viscosity photo-curable benzoxazines (BZs) are designed and synthesized for use in stereolithography 3D printing. An initial investigation shows that the thermally polymerized polybenzoxazines (PBZs) have remarkably high T (264 °C) and flexural modulus (4.91 GPa) values.
