How it works is, the bridge's building blocks were created using a 3D printer, which extruded a cement-based mixture in layers to built up the blocks' structure, following an exact computer-made plan.
D printing creates solid objects from the additive process of layering plastics, metal, wood, synthetic fibers, and more.
AMHERST — A UMass Amherst and MIT team have successfully strengthened an aging bridge in Great Barrington with cutting-edge 3D printing, the university announced Thursday. The 3D-printing technique is ...
