1. A method for manufacturing a three-dimensional (3D) object with an additive manufacturing system, comprising a step consisting in printing layers of the 3D object from a part material comprising a polymeric component comprising, based on the total weight of the polymeric component:
from 5 to 95 wt. % of at least one polymer (P1) comprising at least 50 mol. % of recurring units (R1) consisting of an arylene group comprising at least one benzene ring, each recurring unit (R1) being bound to each other through C—C bonds, wherein the recurring units (R1) are such that, based on the total number of moles of recurring units (R1):
less than 90 mol. % are arylene units (R1-a),
at least 10 mol. % are arylene units (R1-b),
wherein (R1-a) is 1,4-phenylene and (R1-b) is 1,3-phenylene; and
wherein (R1-a) and (R1-b) are substituted or unsubstituted, and
from 5 to 95 wt. % of at least one polymer (P2), having a glass transition temperature (Tg) between 140° C. and 265° C., and no melting peak, as measured by differential scanning calorimetry (DSC) according to ASTM D3418.
