AI Technical Summary
In existing technologies, excessively high viscosity of color photosensitive resins can cause nozzle clogging, and the viscosity-reducing effect of diluents can lower the mechanical properties of 3D molded products, making it difficult to balance printing stability and performance.
A photocurable composition containing acrylic resins, oxetine compounds as reactive diluents, pigments, and photoinitiators is used. By optimizing the ratio and structural design, the viscosity is reduced and the pigment dispersion is improved, thus avoiding nozzle clogging while maintaining the mechanical properties of the parts.
It effectively avoids printhead clogging, improves printing smoothness and part strength, adapts to the needs of high-precision color 3D inkjet printing, and reduces production costs.
