Researchers at Waseda University developed a 4D printed vascular stent using micro stereolithography (PuSL) that activates at 37C body temperature. By optimizing polycaprolactone (PCL), the 10mm stents expand naturally without external heating. This innovation targets the 8 billion dollar stent market by simplifying procedures and reducing risk. These bioabsorbable structures eventually dissolve, eliminating long term foreign body presence. 🏥 #3DPrinting #MedTech #4DPrinting #AM
