A coalescing agent for three-dimensional (3D) printing includes a co-solvent, a surfactant having a hydrophilic lipophilic balance (HLB) value that is less than 10, a carbon black pigment, a polymeric dispersant, and a balance of water. The co-solvent is present in an amount ranging from about 15 wt % to about 30 wt % of a total wt % of the coalescing agent. The surfactant is present in an amount ranging from about 0.5 wt % to about 1.4 wt % of the total wt % of the coalescing agent. The carbon black pigment is present in an amount ranging from about 3.0 wt % to about 6.0 wt % of the total wt % of the coalescing agent. The polymeric dispersant has a weight average molecular weight ranging from about 12,000 to about 20,000.

Provided is an ink including water, and an organic solvent, wherein a dried product of the ink has an endothermic peak temperature Tm of 22° C. or higher but 74° C. or lower as measured by differential scanning calorimetry, the differential scanning calorimetry includes first heating, cooling, and second heating, where the first heating is heating the dried product of the ink from −60° C. to 140° C. at a heating rate of 10° C./min, the cooling, which is performed after the first heating, is cooling a heated product obtained in the first heating from 140° C. to −60° C. at a cooling rate of −10° C./min, and the second heating, which is performed after the cooling, is heating a cooled product obtained in the cooling from −60° C. to 140° C. at a heating rate of 10° C./min, and the endothermic peak temperature Tm is an endothermic peak temperature in the second heating.

The present disclosure relates to the use of occluding fluids, such as a high-density fluid (a “z-fluid”) or a low-density fluid (an “a-fluid”), to displace resin within a vat during 3D printing. Further, an a-fluid may act as a protective boundary for a 3D printing resin wherein the a-fluid sits on top of the printing resin. Another embodiment of the disclosure provides a process of assessing which regions of a computer-aided design (CAD) model take advantage of a buoying force supplied by the occluding fluid, such that fewer support structures are needed for printing a final CAD model compared to printing the CAD model without the occluding fluid.

An approach to precision additive fabrication uses jetting of cationic compositions in conjunction with a non-contact (e.g., optical) feedback approach. By not requiring contact to control the surface geometry of the object being manufactured, the approach is tolerant of the relative slow curing of the cationic composition, while maintaining the benefit of control of the deposition processes according to feedback during the fabrication processes. This approach provides a way to manufacture precision objects and benefit from material properties of the fabricated objects, for example, with isotropic properties, which may be at least partially a result of the slow curing, and flexible structures, which may not be attainable using conventional jetted acrylates.
