Title:
THREE-DIMENSIONAL PRINTING MATERIAL, THREE-DIMENSIONAL OBJECT, AND METHOD FOR PRINTING THREE-DIMENSIONAL OBJECT
Document Type and Number:
WIPO Patent Application WO/2024/001603
Kind Code:
A1
Abstract:
The present application provides a three-dimensional printing material, a three-dimensional object, and a method for printing the three-dimensional object. The three-dimensional printing material comprises, by weight in percentage, 40%-80% of a first photocurable component, 5%-50% of a second photocurable component, 5%-15% of a compatibility accelerant, and 0.5%-10% of a photoinitiator, wherein the first photocurable component comprises a first prepolymer and an active monomer, the second photocurable component comprises a second prepolymer, the number-average molecular weight of the first prepolymer is smaller than that of the second prepolymer, and the surface tension of the first prepolymer is different from that of the second prepolymer. According to the three-dimensional printing material and the three-dimensional object provided by the present application, the discharge stability of the three-dimensional printing material can be ensured, and the three-dimensional object formed by using the three-dimensional printing material can give consideration to both hardness and toughness, and has relatively strong environmental stress cracking resistance and temperature resistance.
