Title:
付加造形のための放射線硬化性組成物
Document Type and Number:
Japanese Patent JP7306612
Kind Code:
B2
Abstract:
Described herein are thermoset compositions and kits of compositions suitable for use in additive fabrication processes including high concentrations of urethane methacrylate oligomers having at least one polymerizable group, and a number average molecular weight from 750 to 4000 g/mol, an effective quantity of a monofunctional reactive diluent monomer, a defined concentration of a network building agent having a molecular weight that is lower than the urethane methacrylate oligomer, optionally a photoinitiator, and optionally, additives. Also disclosed are methods of creating three-dimensional parts via additive fabrication processes utilizing urethane methacrylate oligomer-centric compositions, wherein various exposure irradiances, cure temperatures, and oxygen content levels are prescribed, as well as the articles cured therefrom.
