Effect of TPU on Fused Deb Modeling Perbance of ABS/TPU Compounds

(1.College of Chemistry & Materials,Fujian Normal University,Fuzhou 350007,China;2.Fujian Key Laboratory of Pollution Control and Resource Reuse,Fuzhou 350007,China)
Abstract:The 3Dprinting filaments based on ABS/thermoplastic polyurethane (TPU) blends were prepared by a melt blending b.These 3Dprinting filaments were subsequently processed to the standard test samples by fused deb modeling (FDM),and their modeling perbance,mechanical properties,microstructure and rheological properties were investigated.The results indicted that the introduction of TPU improved the modeling perbance of ABS.With the addition of 20wt%of TPU into ABS,the warp shrinkage disappeared in the modeling process.At this weight frb,the molded sample obtained the enhanced notched impact strength of 18.81kJ/m2 and the declined tensile strength of 32.92 MPa,which increased by 95.94 % and decreased by 8.5%,respectively,compared to those of pure ABS .
