摘要： Provided are compositions (which may inks), methods, devices, and systems that are used with 3D printing. The compositions contain fluoropolymer particles, one or more type of a medium, one or more surfactants, and one or more shear thinning agents. The fluoropolymer component can be one or more of polytetrafluoroethylene (PTFE), perfluoroalkoxy, fluorinated ethylene-propylene, and poly ethyl enetetrafluoroethylene. Cartridges that contain the compositions are also provided. Methods of making the compositions, methods of using the compositions for 3D printing, and articles of manufacture, such as medical devices, are also provided.
