Claim 0:
1. A method for making a three-dimensional (3D) article with an additive manufacturing system, the method comprising printing layers of the three-dimensional (3D) article, wherein the layers comprise a polymer composition (C) comprising:
a poly(aryl ethersulfone) (PAES) polymer; and
at least one component selected from the group consisting of reinforcing agents, photoinitiators, tougheners, plasticizers, colorants, pigments, antistatic agents, dyes, lubricants, thermal stabilizers, light stabilizers, flame retardants, nucleating agents and antioxidants;
wherein the poly(aryl ethersulfone) (PAES) polymer comprises:
recurring units (RPAES) of formula (L):, at least one terminal group of formula (M):, wherein:
each R1 is independently selected from the group consisting of a halogen, alkyl, alkenyl, alkynyl, aryl, ether, thioether, carboxylic acid, ester, amide, imide, alkali or alkaline earth metal sulfonate, alkyl sulfonate, alkali or alkaline earth metal phosphonate, alkyl phosphonate, amine and quaternary ammonium;
each L1 is —(CH2)n—CH2—CH═CH2 or a radical containing the same;
each i is an independently selected integer from 0 to 4;
n is an integer from 1 to 10;
T is selected from the group consisting of a bond, —CH2—; —O—; —SO2—; —S—; —C(O)—; —C(CH3)2; —C(CF3)2—; —C(═CCl2)—; —C(CH3)(CH2CH2COOH)—; —N═N—; —RaC═CRb—,

where each Ra and Rb, independently of one another, is a hydrogen or a C1-C12-alkyl, C1-C12-alkoxy, or C6-C18-aryl group; —(CH2)m— and —(CF2)m— with m being an integer from 1 to 6; an aliphatic divalent group, linear or branched, of up to 6 carbon atoms; and combinations thereof,
wherein the printing is conducted at a temperature of at least 200° C.
