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. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.
