3D 打印已广泛用于航空航天、汽车和医疗行业的快速原型制作以及小批量生产。然而，对于大批量生产来说，传统制造工艺（即注塑成型和 CNC 加工）比 3D 打印更经济。此外，由于商用 3D 打印机的构建尺寸有限，当前的 3D 打印技术无法制造大型部件。为了提高 3D 打印吞吐量和构建体积，最近引入了一种新颖的协作 3D 打印技术。协作 3D 打印是一种增材制造工艺，其中各个移动 3D 打印机协作同时打印零件，从而提高打印速度和构建体积。虽然协同 3D 打印有潜力更有效地制造更大的组件，但协同 3D 打印制造的组件的机械性能尚未得到系统表征。本文旨在开发一种数据驱动的预测模型，用于预测通过协作 3D 打印制造的组件的拉伸强度。实验结果表明，该预测模型能够预测拉伸强度并识别影响拉伸强度的重要因素。
3D printing has been extensively used for rapid prototyping as well as low-volume production in aerospace, automotive, and medical industries. However, conventional manufacturing processes (i.e., injection molding and CNC machining) are more economical than 3D printing for high-volume mass production. In addition, current 3D printing techniques are not capable of fabricating large components due to the limited build size of commercially available 3D printers. To increase 3D printing throughput and build volume, a novel cooperative 3D printing technique has been recently introduced. Cooperative 3D printing is an additive manufacturing process where individual mobile 3D printers collaborate on printing a part simultaneously, thereby increasing printing speed and build volume. While cooperative 3D printing has the potential to fabricate larger components more efficiently, the mechanical properties of the components fabricated by cooperative 3D printing have not been systematically characterized. This paper aims to develop a data-driven predictive model that predicts the tensile strength of the components fabricated by cooperative 3D printing. Experimental results have shown that the predictive model is capable of predicting tensile strength as well as identifying the significant factors that affect the tensile strength.
