摘要： Build materials for 3D printing applications are described herein which, in some embodiments, comprise monomeric species operable for producing articles with high Tg and/or high heat deflection temperature while maintaining shelf stability. In one aspect, a polymerizable liquid comprises at least 20 weight percent isocyanurate polyacrylate; a photoinitiator component; and a crystallization inhibitor component comprising monomeric curable material, oligomeric curable material or mixtures thereof, wherein the polymerizable liquid does not exhibit crystallization over a period of 28 days at a storage temperature of 5-10° C.

摘要： Build materials for 3D printing applications are described herein which, in some embodiments, comprise a dye component operable to alter spectral characteristics of the printed part over the course of the build cycle. In some embodiments, for example, the dye component can provide desirable light penetration depth during article printing and sufficient optical clarity during final light curing processes.
