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.
材料喷射（MJ）型3D打印机被认为是最通用的3D打印机类型之一，能够进行全彩打印和多材料打印。然而，据我们所知，关于全彩MJ技术发展的学术研究很少，而且商业树脂的配方是保密和专有的。在本文中，我们深入了解了可用于我们自制的MJ全彩3D打印机的多个压电喷头进行打印的原色CMYKW（青色、品红色、黄色、黑色和白色）光固化树脂的制备。对构成树脂的成分，如光引发剂、低聚物、单体和交联剂进行了系统的调整和表征，以获得高性能的MJ可打印树脂。随后，用CMYKW颜色对制备的树脂进行着色，并展示了它们在全彩打印中呈现高质量色彩外观的能力。
