摘要本研究的目的是评估用于三维砂型打印机的商用美国铸造耗材的性能特征。选取的硅砂为57粒细度（GFN）和70粒细度。这些砂是一种高纯度的圆形颗粒二氧化硅，具有低痕量污染物，以减少任何可能的污染影响。选择呋喃树脂体系是因为它是美国3D打印砂中应用最广泛的树脂体系。呋喃树脂系统由美国国内铸造供应商提供。印刷样品为传统的拉伸试样和矩形试样，用于密度测定。测试了样品的以下性能：抗拉强度、着火损失、密度、划痕硬度和渗透性。调查结果证实，测试的国产树脂体系和硅砂符合原始设备制造商的性能。
AbstractThe purpose of this study was to assess the performance characteristics of commercially available US foundry consumables for use in three-dimensional sand printers. The silica sands selected were 57 grain fineness number (GFN) and 70 GFN. These sands were a high-purity round grain silica and had low trace contaminates, to reduce any possible influence from contaminates. The furan resin system was selected since it is the most widely utilized resin system for 3D printed sand in the USA. The furan resin system was from a domestic US foundry supplier. The printed samples were traditional tensile specimen and rectangle samples for the determination of density. The samples were examined for the following properties: tensile strength, loss on ignition, density, scratch hardness, and permeability. The results of this investigation confirmed that the tested domestic resin system and silica sands matched the original equipment manufacturer performance properties.
