This study investigates the compressive mechanical properties of nozzle temperature-graded triply periodic minimal surface (TPMS) lattice structures, commonly employed in advanced engineering applications including energy absorption, thermal protection, biomedical implants, and acoustic insulation. The main aim of this study is to examine the effects of different TPMS structures and printing parameters specifically nozzle temperature, layer thickness, and nozzle temperature variations across layers on the compressive properties, utilizing the Taguchi experimental design methodology. The novelty of this research lies in evaluating the effects of TPMS structures printed with graded nozzle temperature on compression mechanical performance. In addition, applying the Taguchi method to evaluate the effects of TPMS structures printed with both graded and uniform nozzle temperatures on compression mechanical performance also adds novelty to the study. The results indicate that the sample exhibiting the greatest energy absorption (89.58 J) was the diamond structure fabricated with a graded nozzle temperature and a layer thickness of 0.15 mm. The maximum force was 22.24 kN in the gyroid structure, produced with a graded nozzle temperature and a layer thickness of 0.1 mm. In addition, the diamond structure was uniformly printed at a layer thickness of 0.1 mm and a nozzle temperature of 225° C, resulting in a maximal first peak force of 5.59 kN. This research suggests optimization strategies to balance mechanical performance with production efficiency and costs, highlighting the potential of temperature-graded TPMS structures for practical engineering applications.
