The present disclosure provides apparatuses and methods for manufacturing three-dimensional objects. Each additive manufacturing apparatus () includes: a) a reservoir () for receiving hardenable material; b) a first movable light engine () providing a first light radiation configuration; a second light engine () providing a second light radiation configuration that is different than the first light radiation configuration; and d) a light altering structure (). The light altering structure is located between the reservoir and light radiated from at least one of the first movable light engine or the second light engine. The first movable light engine is configured to radiate light onto a first focal plane () within the reservoir containing the hardenable material and the second light engine is configured to radiate light onto a second focal plane () within the reservoir containing the hardenable material. The method includes: a) obtaining a hardenable material disposed in a reservoir; b) selectively radiating light having a first light radiation configuration from a first movable light engine; and c) selectively radiating light having a second light radiation configuration from a second light engine onto a second focal plane within the hardenable material. The apparatuses and methods can advantageously form objects having different resolutions on demand using the same apparatus, plus optionally can blend light from multiple light engines.

Provided are methods for making shaped fluoropolymer by additive processing using fluoropolymer particles, polymerizable binder and extraction with supercritical fluids. Also provided are 3D printable compositions for making shaped fluoropolymer articles and articles comprising a shaped fluoropolymer.

Additive processing of fluoropolymers

Described herein is a curable composition comprising an amorphous fluoropolymer having an iodine, bromine and/or nitrile cure site; a peroxide cure system comprising a peroxide and a Type II coagent; and a photoinitiator, wherein the curable composition is substantially free of a binder material. Also described herein, are methods of curing the curable composition using actinic radiation and articles thereof.

Fluorinated elastomers cured by actinic radiation and methods thereof
