Tomsk Polytechnic University researchers have developed 3D-printed gyroid scaffolds that activate their shape-memory effect at physiological temperatures of 36-39 °C. By plasticizing polylactide with 10% polyethylene glycol, these biodegradable implants can be compressed for minimally invasive surgery and expand to fill bone defects with 97% accuracy in 6 minutes. This shift to responsive 4D printing eliminates the need for high-temperature triggers that previously damaged living tissues. 🧬 #3DPrinting #Biomedical #4DPrinting #AdditiveManufacturing #BoneEngineering
