본 발명은 적층 가공용 열가소성 중합체에 관한 것으로, 여기에서 상기 열가소성 중합체는 염소화된 단량체 단위로부터 유도되고, 상기 열가소성 중합체는 적층 가공에 적합한 용융 유속(MFR)을 갖는다. 또한 본 발명은 적층 가공에 의해 형성되는 3D 제품의 제조 방법에 관한 것으로, 여기에서 상기 3D 제품은 염소화된 단량체 단위로부터 유도된 열가소성 중합체 또는 염소화된 단량체 단위로부터 유도된 적어도 하나의 열가소성 중합체; 및 적어도 하나의 안정제를 포함하는 열가소성 조성물을 포함하며, 여기에서 상기 열가소성 중합체 또는 조성물은 적층 가공에 적합한 MFR을 갖는다. The present disclosure is directed to a thermoplastic polymer for additive manufacturing, wherein the thermoplastic polymer is derived from a chlorinated monomer unit, wherein the thermoplastic polymer has a melt flow rate (MFR) suitable for additive manufacturing. The present disclosure is also directed to a method of making a 3D product formed by additive manufacturing, wherein the 3D product comprises a thermoplastic polymer derived from a chlorinated monomer unit or a thermoplastic composition comprising at least one thermoplastic polymer derived from a chlorinated monomer unit; and at least one stabiliser, wherein the thermoplastic polymer or composition has a MFR suitable for additive manufacturing.
