Vascular stents typically come in a number of different lengths and diameters. The physician implanting these chooses which would best fit individual patients, but often the available sizes are not ideal for certain cases. Researchers at Northwester University turned to 3D printing to be able to create stents of any size, allowing them to be perfectly customized to each patient’s unique anatomy.
They tweaked a technique called projection micro-stereolithography (PµSL), which works by projecting light onto a liquid photo-curable material that quickly solidifies.
