CJ270 uses MJP (MultiJet Printing) technology combined with UV curing. It precisely jets tiny droplets of photosensitive resin and cures them instantly with UV light, building the model layer by layer. Unlike multicolor FDM, which creates color by switching between different colored filaments, CJ270 combines CMYK, white, and clear materials during printing to achieve smooth gradients, natural skin tones, subtle color transitions, and transparent effects. DLP also uses photosensitive resin and UV curing, but typically cures an entire layer through projected light. CJ270 jets and cures materials through multiple printheads, enabling multiple materials and colors to be integrated into a single print.
