    摘要: An apparatus for forming an object by an additive process, commonly referred to as 3-D printing, is provided. The apparatus includes a filament comprising a series of irregularities along the length of the filament, a nozzle depositing a layer of melted material onto a surface and a feeder feeding the filament to the nozzle. A heating element melts the filament and a controller controls the position of the nozzle in a plane to control the configuration of the layer of melted material deposited by the nozzle. Additionally, a method for forming polymer filament used in 3-D printing devices is also provided. The method includes the steps of melting a polymer, selecting an extrusion characteristic calculated to induce a polymer flow instability and extruding the melted polymer using the selected extrusion characteristic to produce an extrusion having distortions created by the polymer flow instability.

    摘要: A composite material includes a cementitious composition and a plurality of fibers disposed in the cementitious composition. Each of the plurality of fibers includes a plastic component. Each of the plurality of fibers further includes a surfactant and a metal oxide, each independently heterogeneously dispersed throughout each of the plurality of fibers. A method of forming the composite material includes the step of combining the plastic component, the surfactant, and the metal oxide, to form the plurality of fibers. The method further includes the step of disposing the plurality of fibers in the cementitious composition to form the composite material.
