Abstract Objective To explore the effects of different pore sizes of 3D printed triply periodic minimal surfaces (TPMS) primitive scaffolds on the proliferation and differentiation of osteoblasts MC3T3E1，and to provide a theoretical basis for the design of subsequent 3D printed personalized prosthetic porous structures. Methods Design and fabrication of TPMS substrate scaffolds with three pore sizes (400 μm，600 μm and 800 μm) were conducted based on TPMS implicit surface functions and selective laser melting (SLM).The scaffolds with different pore sizes were co-cultured with osteoblasts MC3T3-E1 and their effects on osteoblast proliferation and differentiation were evaluated by CCK-8，Cytoskeleton staining，alkaline phosphatase activity and western blot (WB) analysis. Results Scanning electron microscopy showed that TPMS primitive scaffolds with different pore sizes were successfully fabricated and osteoblasts MC3T3-E1 showed good adhesion in the scaffolds.The results of CCK-8 experiments indicated that the proliferation of MC3T3-E1 increased significantly with increasing pore size.In addition，the TPMS primitive scaffold exhibited the highest alkaline phosphatase activity at a pore size of 600 μm.WB analysis further revealed that the expression of collagen type Ⅰ(Col Ⅰ)，Runt related transcription factor 2(Runx2) and osteopontin (OPN) proteins were also highest in the 600 μm group. Conclusion As the pore size increased，the 3D printed TPMS scaffold demonstrates enhanced osteoblast proliferation.Furthermore，a pore size of 600 μm is optimal for osteoblast differentiation.
