▎ 摘  要

NOVELTY - Light/heat cured shape memory hybrid material comprises a light/heat curing elastic material and a transition phase material, where the light/heat curing elastic material is cross-linked and cured, blended with the transition phase material before curing to obtain shape memory hybrid material, the light/heat-curable elastic material is light-curable elastic resin, heat-curable elastic resin, or light-heat-double crosslinkable elastic resin, and the transition phase material melting/solidifying or glass transition with temperature changes, or absorb/volatilize solvent soft hardness change. USE - The light/heat cured shape memory hybrid material is useful in three-dimensional printing (claimed). ADVANTAGE - The material avoids reflecting UV light or clogging the extrusion port during the photo-curing process, and ensures that the material matrix fully cross-linked; prints intelligent structure with specific shape memory effect through the three-dimensional printing technology; and adjusts shape memory effect and mechanical characteristics of the three-dimensional printing shape memory structure. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing the light/heat curing shape memory hybrid material, comprising mixing the light/heat curing elastic material and the phase material, mixing the transition phase material with light/heat curing elastic material in the form of particles, where the particle size of the transition phase material is 0.02-50 μm; and Use of the light/heat cured shape memory hybrid material in three-dimensional printing, comprising the curing and cross-linking of the light/heat curing elastic material and the transition phase material is realized by UV light irradiation during printing or by UV light or heating after printing and forming.
