    Abstract: A method of printing a three dimensional article is provided wherein particles are bonded together with chemical bonds having a bond strength of at least 10 kJ/mol. In one aspect, kits for three dimensional printing are described herein. In some embodiments, a kit described herein comprises a substantially dry particulate material (20) comprising an insoluble filler having a first functional group on the surface of the insoluble filler; and a fluid binder material (26) comprising a multifunctional linker having a second functional group, wherein the insoluble filler is insoluble in the fluid binder material and wherein the first functional group and the second functional group can react with one another to form a covalent bond between the insoluble filler and the multi functional linker.

    Abstract: 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.

    Abstract: In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises 20-60 wt. % oligomeric curable material; 10-50 wt. % cyclocarbonate (meth)acrylate monomer; and 0.1-5 wt. % photoinitiator, based on the total weight of the ink. Additionally, in some cases, the ink further comprises one or more additional curable materials differing from the oligomeric curable material and the cyclocarbonate (meth)acrylate monomer. An ink described herein, in some embodiments, also comprises one or more additional component that are non-curable.

    Abstract: In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises up to 80 wt. % oligomeric curable material; up to 80 wt. % monomeric curable material; up to 10 wt. % photoinitiator; up to 1 wt. % non-curable absorber material; and up to 10 wt. % one or more additional components, based on the total weight of the ink, and wherein the total amount of the foregoing components is equal to 100 wt. %. Additionally, the photoinitiator is operable to initiate curing of the oligomeric curable material and/or the monomeric curable material when the photoinitiator is exposed to incident curing radiation having a peak wavelength λ. Moreover, the ink has a penetration depth (Dp), a critical energy (Ec), and a print through depth (DPT) at the wavelength λ of less than or equal to 2×Dp.
