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.
Claims13
A 3D-printed applicator, comprising:
- a. an applicator head having:
- i. a lattice structure that provides structural strength and fluid retention,
- ii. a plurality of bristles projecting from the lattice structure, the plurality of bristles having a variety of lengths and diameters, and
- iii. a plurality of reinforcement wires that extend between one or more mid-sections of the plurality of bristles;
- and
- b. a handle connected to the applicator head.
