To access the full potential of the semicrystalline polymer networks, we investigated their processing into arbitrary shapes via 3D printing. We chose the formulation containing 100% CHTT as crosslinker, which led to the highest absolute crystallinity in bulk studies along with the highest tensile strength. A custom-built heated digital light processing (DLP)-based 3D printer was utilized, with which the temperature can be controlled precisely enough to keep the entire formulation in its liquid crystalline state throughout the printing process. In an initial test, we irradiated a droplet of formulation in the heated vat, which causes solidification in its crystalline state to take place after around five seconds (Supplementary Video 1). A subsequently printed resolution test chip (Figure ) demonstrates excellent printing resolution after removing the excess formulation by sonication of the specimen in toluene (Figure ). Good layer adhesion of macroscopic 3D objects was demonstrated by printing pyramid specimens (Figure ).
