3D-printed chain mail and more: New method combines thick inks and patterned light for faster, finer structures

For decades, people using 3D printers have faced a tough decision: print quickly, print parts with fine features or print materials that meet performance requirements. Light-based 3D printers are fast and precise but limited in what materials they can use. Extrusion-based techniques can handle a wider range of functional materials but sacrifice speed and fine details.
