Abstract: The present invention relates to: a polycarbonate resin composition that is for 3D printing and has excellent shape retention ability and interfacial adhesion; and a pellet for 3D printing and filament for 3D printing, wherein the pellet and filament contain the polycarbonate resin composition. More specifically, the present invention relates to a polycarbonate resin composition for 3D printing, and a pellet and a filament that are for 3D printing and comprise the polycarbonate resin composition, wherein the polycarbonate resin composition comprises a specific combination of a polycarbonate (PC) resin, a polybutylene terephthalate (PBT) resin, a carbon black master batch, and a carbon fiber, retains the excellent mechanical properties of the polycarbonate resin, and has an excellent balance of particular properties, such as shape retention ability and interfacial adhesion, required of 3D printing filaments.

Abstract: A tray for transporting a semiconductor device includes a plate, a loading portion on the plate and configured to support the semiconductor device, and a sidewall portion on the plate and surrounding at least a portion of the loading portion, wherein the sidewall portion includes a first sidewall, and the first sidewall includes a first inclined portion extending from the loading portion and defining a first angle with respect to an upper surface of the loading portion, and a first guide portion extending from the first inclined portion and defining a second angle with respect to the upper surface of the loading portion, the second angle being smaller than the first angle, and the first angle and the second angle are acute angles.

Abstract: The present invention relates to a polybutylene terephthalate resin composition having excellent flame retardancy and hydrolysis resistance and a molded article produced therefrom and, more specifically, to a polybutylene terephthalate resin composition and a molded article produced therefrom, the polybutylene terephthalate resin composition having hydrolysis resistance and heat resistance that are improved by melt-processing a polybutylene terephthalate resin by using polycyclohexylenedimethylene terephthalate resin, and simultaneously having flame retardancy and impact resistance that are improved by using a phosphorus-based flame retardant and a compatibilizer.
