Abstract: The present invention relates to a polycarbonate resin composition for 3D printing and a 3D printing filament comprising same and, more specifically, to a polycarbonate resin composition for 3D printing and a 3D printing filament comprising same, the polycarbonate resin composition comprising a specific combination of a polycarbonate (PC) resin, a polybutylene terephthalate (PBT) resin, a superplasticizer, and an impact modifier, wherein the polycarbonate resin retains superior mechanical properties while particular properties, such as an output performance, a winding property, and an anti-shrinkage property, required for 3D printing filaments, are excellently balanced.

Abstract: The present invention relates to a polysiloxane-polycarbonate copolymer and a method of manufacturing the same. More specifically, the present invention relates to a polysiloxane-polycarbonate copolymer in which the molecular weight of the siloxane monomer constituting the copolymer is maintained in a specifically high level and thus excellent low-temperature impact resistance can be achieved even with low siloxane content, and the viscosity of the copolymer is maintained in a low level and thus flowability and moldability can be improved; and a method of manufacturing the same.
