Abstract

See full text

In one aspect, methods of printing a three-dimensional article are described herein. In some embodiments, a method described herein comprises jetting an ink at a temperature Tl onto a substrate at a temperature T2 to form a layer of the ink on the substrate. The method further comprises subsequently curing the layer of the ink. In some embodiments, Tl is greater than T2 and the ink in an uncured state has a liquid-gel transition temperature below T1 and above T2. Further, the layer of the ink is deposited on the substrate at a rate R1 in mg/s/in2 that is within 60% of a gelation rate R2 of the ink in inverse minutes in an uncured state at T2. The ink can comprise a curable material and a gellant.
