Abstract Lattice channels designed for hot stamping, metal injection, and die casting should have high heat trans- fer and structural performances. In this study, a thermal fluid-structure interaction (TFSI) one-way cou- pled model is developed to estimate the heat transfer and stress characteristics of a face-centered cubic with vertical struts (FCCZ) lattice channel. Based on the simulation model, the heat transfer and stress characteristics of the FCCZ lattice channel produced by metal additive manufacturing (AM) are analyzed in terms of the thermal fluid field, convective heat transfer coefficient, pressure drop, and stress distri- bution by varying the porosity and inlet velocity. Considering the thermal-structural performance factor (TSPF), the optimum porosity of the FCCZ lattice channel is determined as 0.8. In addition, the perfor- mances of the FCCZ lattice channels using 17-4 PH, H13, and maraging steel are compared. The perfor- mance of the H13 channel is superior to those of the 17-4 PH and maraging steel channels.
