摘要： 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 the 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 rigid rod-forming arylene units (R1-a), and at least 10 mol. % are kink-forming arylene units (R1-b), 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.

摘要： The present disclosure relates to method for manufacturing three-dimensional (3D) objects using an additive manufacturing system wherein the part material comprises a combination of at least one poly(aryl ether ketone) polymer (PAEK) and at least one poly(aryl ether sulfone) (PAES). In particular, the present disclosure relates to part material incorporating PAEK and PAES, for example in the form of filaments or spherical particles, for use in additive manufacturing systems to print 3D objects.
