Material jetting (MJ)-type 3D printers have been considered as one of the most versatile types of 3D printers, enabling full-color printing and multi-material printing. However, to the best of our knowledge, there are few academic studies on the development of full-color MJ technologies, and the formulation of commercial resins is confidential and proprietary. In this paper, we give an insight into the preparation of photocurable resins in the primary CMYKW (cyan, magenta, yellow, black, and white) colors that are printable with the multiple piezoelectric heads of our homemade MJ full-color 3D printer. The components comprising the resins, such as the photo-initiator, oligomers, monomers, and crosslinkers, were methodically adjusted and characterized to achieve high-performance MJ printable resins. Subsequently, the prepared resins were colored with the CMYKW colors and their ability of high-quality color appearance in full-color printing was demonstrated. View Full-Text
