With the advent of the industrial "5.0" era, personalized customization has been pushed into the wave of the times, and monochrome 3D printing technology has been difficult to meet the diverse and personalized needs of users. The SLA full-color 3D printers that have been put into use on the market are bulky, expensive, and complicated to operate, and cannot satisfy more and more individual users. To this end, the team solved challenging problems such as uneven mixing of consumables, narrow color coverage, and low color accuracy by designing a new type of mixing nozzle, developing a color mixing scheme for consumables, and improving the 3D printing control system. Design and manufacturing provides a new technical solution, which plays an important role in promoting the development of full-color 3D printing technology. The research results have broad development prospects and huge development potential in the fields of cultural creativity, medical and health care, cultural heritage restoration, and remote sensing surveying and mapping.
