Abstract
Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Wires and their parameters are defined within the new file format, and objects may be processed to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.
