Beschreibung
Zusammenfassung:	The embodiment of the invention discloses photocuring molding slurry, a preparation method and a curing method. The photocuring molding slurry comprises up-conversion nanoparticles and photocuring resin, and the up-conversion nanoparticles can emit high-energy light when excited by low-energy light, namely emit ultraviolet light when receiving near-infrared light irradiation, so that the slurry disclosed by the invention has two curing modes: 1 the slurry is directly cured by the ultraviolet light; and 2 the up-conversion nanoparticles are excited through near-infrared light to generate ultraviolet light, and the slurry is cured. Due to the fact that the cost of the near-infrared light is low, the cost of the three-dimensional photocuring molding technology can be effectively reduced by using the photocuring molding slurry disclosed by the invention. Besides, when the photocuring molding slurry is applied to an exposure type volume 3D printing technology, as near-infrared light has better penetrability than u
