Recently, Additive Manufacturing (AM) has been widely used in many applications. For a particular AM component, the choice of available AM processes is critical to the component’s quality, mechanical properties, and other important factors. In that context, this article presents an efficient decision support system for the selection of an appropriate AM process. A novel hybrid Multi-Criteria Decision Making (MCDM) technique has been proposed to select an appropriate AM process from available AM processes. The Best Worst Method (BWM) is used to determine optimal weights of criteria and the Proximity Indexed Value (PIV) method is employed to rank the available AM processes. For benchmarking the abilities of an AM process, a conceptual model of spur gear was fabricated by four available AM processes viz., Vat Photopolymerization (VatPP), Material Extrusion (ME), Powder Bed Fusion (PBF), and Material Jetting (MJ). Additionally, Dimensional accuracy (A), surface roughness (R), tensile strength (S), percentage elongation (%E), heat deflection temperature (HDT), process cost (PC) and build time (BT) has been considered as most significant criteria. Further, sensitivity analysis has been performed to validate the reliability of the results. The results suggested that the Material Jetting (MJ) process produces dimensionally accurate and quality parts among available alternatives AM processes. The ranking obtained using the PIV method is consistent and reliable.

最近，增材制造（AM）已被广泛用于许多应用中。对于特定的AM组件，可用AM工艺的选择对于组件的质量，机械性能和其他重要因素至关重要。在这种情况下，本文提出了一个有效的决策支持系统，用于选择适当的AM流程。已经提出了一种新颖的混合多标准决策（MCDM）技术，以从可用的AM过程中选择合适的AM过程。最佳最差方法（BWM）用于确定标准的最佳权重，而邻近指标值（PIV）方法用于对可用的AM流程进行排名。为了对AM工艺的能力进行基准测试，正齿轮的概念模型是由四个可用的AM工艺制成的，即Vat Photopolymerization（VatPP），材料挤出（ME），粉末床融合（PBF）和材料喷射（MJ）。此外，尺寸精度（A），表面粗糙度（R），抗张强度（S），伸长率（％E），热变形温度（HDT），加工成本（PC）和制造时间（BT）被认为是最多的重要标准。此外，已经进行了敏感性分析以验证结果的可靠性。结果表明，材料喷射（MJ）工艺可在可用的替代AM工艺中生产尺寸精确且质量高的零件。使用PIV方法获得的排名是一致且可靠的。过程成本（PC）和构建时间（BT）被认为是最重要的标准。此外，已经进行了敏感性分析以验证结果的可靠性。结果表明，材料喷射（MJ）工艺可在可用的替代AM工艺中生产尺寸精确且质量高的零件。使用PIV方法获得的排名是一致且可靠的。过程成本（PC）和构建时间（BT）被认为是最重要的标准。此外，已经进行了敏感性分析以验证结果的可靠性。结果表明，材料喷射（MJ）工艺可在可用的替代AM工艺中生产尺寸精确且质量高的零件。使用PIV方法获得的排名是一致且可靠的。
