摘要本文旨在研究通过在3d打印（3DP）成型模具的铸件中嵌入薄膜传感器，特别是薄膜热电偶（TFTC）来构建“智能模具”的可行性。本研究探讨薄膜传感器能否有效地铸造成较大的金属结构，以及传感器能否在铸造过程中存活下来。该研究包括制作3d打印模具，生产A356铝和电镀镍的铸造搭接测试棒，通过力学测试对其进行表征，以找到最佳的工艺条件，使嵌入式薄膜传感器与铸造材料之间的结合强度最大化。最后制作模具，并在模具内放置嵌入式传感器进行铸造。一些嵌入式传感器在铸造过程中幸存下来。利用嵌入式传感器实现了铸造过程的现场监测。
Department of Mechanical Engineering, University of Wisconsin-Madison, 1513 University Ave., Madison, WI 53706 Reviewed, accepted August 26, 2005 ABSTRACT This paper is to investigate the feasibility of constructing “smart tooling” by embedding thin film sensors, specifically, thin film thermocouples (TFTC) in castings made by molds formed by 3 Dimensional Printing (3DP). This study investigates whether thin film sensors can effectively be cast into larger metal structures and if the sensors survive the casting process. The investigation includes making 3DP molds to produce cast lap joint test bars of aluminum A356 and electroplated nickel to characterize by mechanical testing to find the best process conditions to maximize bond strength between the embedded thin film sensors and the cast material. Lastly molds were made and embedded sensors were placed inside the mold for casting. Some of the embedded sensors survived the casting process. In-situ monitoring of casting process with the embedded sensors was accomplished.
