AI and a Hybrid 3D Printer Just Built Functional Blood Vessel Networks in a Lab
Researchers at Notre Dame and Harvard Medical School used Bayesian optimization and a hybrid extrusion/aerosol printer to build vascularized tissue scaffolds with channels as small as 5-6 microns. Endothelial cells attached, formed linings, and fluid flowed through.
SHAPE as Medicine: How 3D-Printed Cell Geometry Could Become a Therapeutic Tool
University of Nottingham researchers are using two-photon polymerization to print microscale scaffolds that control cell shape — with early evidence that geometry alone can direct how cells grow, migrate, and potentially heal.
Northwestern Prints Neurons That Signal Living Brain Cells
Northwestern University researchers used aerosol jet printing to create electronic neurons from MoS₂ and graphene that establish two-way communication with living mouse brain cells.
3D Printed Organs: What TV Gets Wrong and Where the Science Actually Is
Amazon's Scarpetta depicts transplantable bioprinted organs in 2026. The actual frontier is more interesting than the fiction — and much further away than any TV writer suggests.
