Abstract

The influence of printing variables on microstructural and mechanical behaviors on the 316 L stainless steel (316 L SS), produced via an additive manufacturing process, named as bound metal deposition (BMD), was investigated in this study. The printing parameters varied were infill density, diameter of the nozzle, and thickness of layers, which dictate the mechanical properties, surface roughness, and crack morphology of the samples. Based on the experimental investigation, it was found that the tensile properties were increased when the nozzle diameter and infill density were higher. The highest obtained ultimate tensile strength (UTS) was 402 ± 17 MPa, where the sample was fabricated with the following parameters: 0.40 mm nozzle diameter, 25% infill density, and 0.10 mm layer. The influence of the nozzle diameter also impacted the surface roughness, where a worse surface finish was noticed for the larger nozzle diameter.

不锈钢 316L 的结合金属沉积：工艺变量对微观结构和机械性能的影响

本研究调查了印刷变量对 316 L 不锈钢（316 L SS）微观结构和机械性能的影响，该不锈钢是通过一种名为 "结合金属沉积"（BMD）的快速成型工艺生产的。打印参数包括填充密度、喷嘴直径和层厚度，这些参数决定了样品的机械性能、表面粗糙度和裂纹形态。实验研究发现，喷嘴直径和填充密度越大，拉伸性能越高。最高极限拉伸强度（UTS）为 402 ± 17 兆帕，样品的制造参数如下：喷嘴直径为 0.40 毫米，填充密度为 25%，层厚为 0.10 毫米。喷嘴直径对表面粗糙度也有影响，喷嘴直径越大，表面粗糙度越差。

期刊介绍： Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
