Abstract

Acrylonitrile–butadiene–styrene (ABS) is the main material used in fused deposition modeling (FDM), which has good toughness and strength, but the single ABS material has poor heat resistance, which tends to cause warping and deformation during the printing process. Polycarbonate (PC) exhibits good performance in heat resistance, allowing it to maintain stable performance at higher temperatures. In this work, PC was used as a blending modifier to prepare five kinds of ABS/PC composite filaments, and the mechanical and thermal properties of the ABS/PC (Acrylonitrile–butadiene–styrene/Polycarbonate) composite filaments were studied and analyzed. Results showed that the glass transition temperature (Tg) of the blend increased continuously as the PC content increased. When the mass fraction of ABS/PC was 50/50, the glass transition temperature of the blend increased by 21.21%, and the tensile strength of the composites reached 40.23 MPa, which was an increase of 36.47% compared with that of pure ABS. However, the impact strength of the composites decreased with the addition of PC. Moreover, with the increase in the mass fraction of PC, the printing accuracy error increased from 0.02 to 0.18 mm. The results of this paper will promote the improvement of ABS printing performance and enrich the available materials for FDM.
