1. A three-dimensional printing method comprising selectively forming a three-dimensional structure from a polymer composition, wherein the polymer composition comprises a thermally conductive particulate material distributed within a thermoplastic polymer matrix, wherein the thermoplastic polymer matrix includes a liquid crystalline polymer in an amount from about 30 wt. % to about 90 wt. % of the polymer composition, wherein the polymer composition does not contain an additional filler, and further wherein the polymer composition exhibits a through-plane thermal conductivity of about 0.10 W/m-K or more and a flexural strength from about 20 to about 500 MPa as determined in accordance with ISO Test No. 178:2010 at 23° C.
