3D printing blood vessels and metal

Above, researchers at UPenn and MIT print blood vessels, using sugar. Once the sugar hardens, cells suspended in gel are added. Once the gel solidifies, the sugar is dissolved and removed. Below, another video shows a process where powdered stainless steel is printed using a binder (weak glue), then infused with bronze.
