Abstract: Methods and apparatuses (400) suitable for use in 3D-printing of gels from a solution (470) comprising a polymerizable material dispersed in a solvent are described. Such methods and apparatuses (100) include features (493) to control the relative saturation of the solvent in a gas phase region around the gel during the 3D-printing process.

Abstract: Methods of manufacturing fuel injector nozzle structures such as, e.g., nozzle plates, valve guides, combinations of nozzle plates and valve guides, etc., as well as other articles incorporating microstructured features. The methods may employ multiphoton processes to form microstructured patterns on a three-dimensional structured surface to provide nozzle structures and other articles that include finished microstructured features such as, e.g., through-holes extending from one or more cavities, where at least a portion of the three-dimensional structured surface is used to form the cavities. Forming a microstructured pattern on a three-dimensional structured surface can reduce the time needed to form nozzle structures that include microstructured features and other nozzle structure features (e.g., cavities) by avoiding the need to form the other nozzle structure features using the multiphoton processes.

Abstract: The method of making a three-dimensional article includes heating a composition comprising a polymer and hollow ceramic microspheres, extruding the composition in molten form from an extrusion head to provide at least a portion of a first layer of the three-dimensional article, and extruding at least a second layer of the composition in molten form from the extrusion head onto at least the portion of the first layer to make at least a portion of the three-dimensional article. Three-dimensional articles are also described. A composition including a polymer and hollow ceramic microspheres is also described. The composition may be a filament. The polymer is at least one of a low-surface-energy polymer or polyolefin. The composition can be useful, for example, in melt extrusion additive manufacturing, for example, fused filament fabrication.
