    摘要： 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.

    摘要： Additives for three-dimensional build materials or inks are described herein which, in some embodiments, can impart flame retardant properties and/or structural enhancements to articles printed from the build materials. In some embodiments, such an additive comprises a compound of Formula I herein, wherein L and Z are ring substituents comprising at least one polymerizable point of unsaturation, and wherein R1 and R2 are independently selected from the group consisting of alkylene and alkenylene, and R3-R6 each represent one to four optional ring substituents, each one of the one to four ring substituents independently selected from the group consisting of alkyl, heteroalkyl, haloalkyl, halo, hydroxyl, alkoxy, amine, amide, and ether, and wherein n is an integer from 1 to 7.
