Metal additive printing technology facilitates unprecedented freedom in the design of mechanical components andhas mostly been used to improve their performance. However, the prediction of fabrication failure is equallyimportant in metal additive manufacturing. To address this challenge, this paper presents an integrated strategythat demonstrates the process from design to fabrication of a cooler. This study adopted a multi-fidelity surrogatemodel and a supporting effect-based prediction algorithm to analyze the geometry of coolers for additivemanufacturing. The original geometry was modified based on the prediction results and fabricated using the laserpowder bed fusion method. The internal space of the modified cooler design was verified using computedtomography scanning, which revealed no defects. Additionally, the fabricated cooler demonstrated a notableimprovement, exceeding 60%. This study demonstrated an effective approach for designing and fabricatingmetal-additive-printed components, considering both functional requirements and fabrication constraints, which canbe widely applied in various fields where performance and reliability are paramount.
