摘要
The invention provides a method for manufacturing a 3D item (10) with a fused deposition modeling 3D printer, the method comprising (a) providing a thermoplastic material (20), wherein the thermoplastic material (20) comprises a first polymer (21) of the semi-crystalline type, wherein the first polymer (21) has a glass temperature (Tg) and wherein the thermoplastic material (20) has a melting temperature (Tm); generating in a generation stage an intermediate 3D printed item (110) by printing the thermoplastic material (20), wherein the thermoplastic material (20) is heated to a temperature equal to or above the melting temperature (Tm), while maintaining during printing an ambient temperature (Ta) to the intermediate 3D printed item under construction below the glass temperature (Tg); and generating in an annealing stage said 3D item (10) by heating the intermediate 3D printed item (110) equal to or above the glass temperature (Tg).
