A new type of biodegradable Polycaprolactone (PCL) based ink that is suitable for 3D inkjet printing has been successfully developed. UV curable PCL was synthesized and mixed with Poly (ethylene glycol) diacrylated (PEGDA) to prepare an ink with suitable viscosity for inkjet printing. 3D structures were printed, their mechanical properties as well as the printing accuracy were measured by nano-indentation and scanning electron microscopy. The hardness of the samples was found to be around 5.62MPa with an elastic modulus of 44.39MPa. It was also found that a postcuring procedure (within 90min) did not show significantl influence on increasing the hardness and elastic modulus of the printed samples.
