Abstract
The present disclosure provides a printable composition. The printable composition includes a polymer, a polymerizable component, a temporary solvent, a photoinitiator, and optionally an inhibitor. The present disclosure also provides an article including an integral blend of a thermoset polymer and a second polymer different from the thermoset polymer. Further, the present disclosure provides a method of making an article. The method includes (i) providing a printable composition; (ii) selectively curing the printable composition to form a gelled article; and (iii) removing at least a portion of the temporary solvent from the gelled article. The method may optionally include (iv) curing unpolymerized polymerizable component remaining before or after step (iii). Also, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a plurality of layers of an article, the article including: an integral blend of 8 to 50 wt. %, inclusive, of a thermoset polymer and 30 to 90 wt. %, inclusive, of a second polymer different from the thermoset polymer, wherein the weight percent is based on the total weight of…
