    Preparation and Properties of Acrylonitrile Butadiene Styrene/Polycarbonate Composite Filament for Fused Deposition Modeling

    Shanlong Che, Guangliang Qu, Jin Ding*, Guochen Wang, Yunyan Hao, Dianchen Li

    Journal of Polymer Materials, Vol.42, No.1, pp. 221-236, 2025, DOI:10.32604/jpm.2025.058587 - 27 March 2025

    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… More >

    Numerical Simulation and Experimental Study of the Stress Formation Mechanism of FDM with Different Printing Paths

    Heping Hou1, Yang Yue1,*, Jian Liu1, Darun Xi2, Shanhui Liu1

    Journal of Renewable Materials, Vol.11, No.1, pp. 273-289, 2023, DOI:10.32604/jrm.2023.021167 - 10 August 2022

    Abstract Environmental contamination has been caused by petroleum-based polymeric materials in the melt deposition process. Nowadays biodegradable materials have been widely used in the fused deposition modeling (FDM) industry, such as polylactic acid (PLA). However, internal complex thermal stress and deformations in part caused by an uneven distribution of PLA filament deposition temperatures during FDM, which will seriously affect the geometric accuracy of the printed part. In order to reduce material waste and environmental pollution during the printing process, the accuracy of PLA part can be improved. Herein, numerical simulation was carried out to investigate the… More >
