Bone bionics and structural engineering have sparked a broad interest in optimizing artificial scaffolds for better bone regeneration. However, the mechanism behind scaffold pore morphology-regulated regeneration remains unclear, making structure design of repair challenging. To address this issue, we carefully assessed diverse cell behaviors mesenchymal stem cells (BMSCs) on β-tricalcium phosphate (β-TCP) with three representative morphologies (i.e., cross column, diamond, gyroid unit, respectively). Among scaffolds, BMSCs β-TCP diamond unit (designated as D-scaffold) demonstrated enhanced cytoskeletal forces, elongated nucleus, faster mobility, osteogenic differentiation potential (for example, alkaline phosphatase expression level D-scaffold were 1.5-2 times higher than other groups). RNA-sequencing analysis signaling pathway intervention revealed that Ras homolog gene family A (RhoA)/Rho-associated kinase-2 (ROCK2) has in-depth participated morphology-mediated behaviors, indicating an important role mechanical transduction scaffold-cell interactions. Finally, femoral condyle defect results showed could effectively promote endogenous regeneration, which osteogenesis rate was 1.2-1.8 groups. Overall, work provides insights into mechanisms developing novel bioadaptive designs.

Additive manufacturing (AM), also known as three-dimensional (3D) printing, has boomed over the last 30 years, and its use accelerated during 5 years. AM is a materials-oriented technology, printing resolution versus scalability/speed trade-off exists among various types of materials, including polymers, metals, ceramics, glasses, composite materials. Four-dimensional (4D) together with versatile transformation systems, drives researchers to achieve utilize high dimensional AM. Multiple perspectives structural materials have been raised illustrated in this review, multi-material (MMa-AM), multi-modulus (MMo-AM), multi-scale (MSc-AM), multi-system (MSy-AM), multi-dimensional (MD-AM), multi-function (MF-AM). The rapid tremendous development methods offers great potential for applications, such aerospace field, biomedical electronic devices, nuclear industry, flexible wearable soft sensors, actuators, robotics, jewelry art decorations, land transportation, underwater porous structures.
