Abstract

A new type of photocrosslinkable polycaprolactone
(PCL)-based ink that is suitable for three-dimensional (3D) inkjet printing has been developed. Photocrosslinkable PCL dimethylacrylate was synthesized and mixed with poly(ethylene glycol) diacrylate to prepare an ink with a suitable viscosity for inkjet printing. The ink performance under different printing environments, initiator concentrations, and postprocess was studied. This showed that a nitrogen atmosphere during printing was beneficial for curing and material property optimization, as well as improving the quality of structures produced. A simple structure, building in the z-direction, demonstrated the potential for thismaterial for the production of 3D printed objects. Cells’ testwas carried out to investigate the biocompatibility of the developed ink.
