| Abstract Scope |
Laser foil printing (LFP) is a metal additive manufacturing (AM) process using laser-based melting of metal foil technique. Using metal foils in AM has advantages over common laser powder-feed processes, allowing for efficient heat transfer and resolving the drawbacks of powder-based AM, such as potential powder inhalation health hazards, balling, spattering, and high powder costs. In this study, we demonstrate the advantage of LFP for embedding sensors into structures using 304L stainless-steel foil as the feed material and two different types of temperature sensors. The first type is a resistance temperature detector (RTD) platinum sensor (Pt 100), and the second type is a k-type thermocouple probe. A detailed study of the sensor embedment through LFP revealed that laser power, dwelling duration, and scanning strategy significantly affect product quality. As a result of this study, we demonstrated the feasibility of fabricating functional parts with embedded sensors using the LFP process. |
