Abstract

In this study, the material extrusion-based additive manufacturing process of TiC steel-bonded carbide slurries with solid contents ranging from 44 to 52 vol% was simulated using ANSYS Polyflow. The flow behavior, including shear stress and viscosity distribution within the barrel and nozzle, was analyzed to evaluate printability. The results show that printability initially improves with increasing solid content, peaking at 50 vol%, after which it declines. Simulation results were validated experimentally, showing good agreement. Optimal printing performance and product precision were achieved when the outlet viscosity ranged from 90 to 132 Pa·s at a printing speed of 10 mm/s. This study demonstrates that numerical simulation is an effective tool for optimizing printing parameters and improving print quality in material extrusion additive manufacturing.

材料挤压增材制造中浆液打印过程的有限元模拟

本研究采用ANSYS Polyflow软件对固含量为44 ~ 52 vol%的TiC钢结硬质合金浆料进行了材料挤压增材制造过程的模拟。分析了筒体和喷嘴内的剪切应力和粘度分布等流动特性，以评估可打印性。结果表明，随着固含量的增加，印刷适性开始改善，在50 vol%时达到峰值，之后下降。仿真结果与实验结果吻合较好。当出口粘度为90 ~ 132 Pa·s，印刷速度为10 mm/s时，印刷性能和产品精度达到最佳。研究表明，数值模拟是材料挤压增材制造中优化打印参数、提高打印质量的有效工具。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
