Waste product from any of a variety of processes (injection molding, selective laser sintering) is processed to form powders that have particle size and distribution optimal for a 3D printing technology known as Composite Based Additive Manufacturing (CBAM). Alternative recycling processes include grinding and sieving, emulsion extruding, and liquid-liquid phase separation.

THREE-DIMENSIONAL PRINTED COMPOSITES USING ENGINEERED POWDERS
A three-dimensional object comprises stacked substrate layers infiltrated by a hardened material comprising engineered powder that is transformed into a substance that flows and subsequently hardens into the hardened material in a spatial pattern that infiltrates positive regions, and does not infiltrate negative regions, in the substrate layers. The powder may be emulsion aggregation powder, chemically -produced toner powder, or a combination. It may be a thermoplastic or thermosettable polymer and may include nylon, elastomers, polyolefins, polyethylene, polyether ether ketone, polyimide, polyetherimide, polyphenylene sulfide, polystyrene, polypropylene, polymethyl methacrylate, and polyaryletherketone, or a combination. The powder particles may have a pre-specified controlled shape and/or anon-homogenous composition. Surface treatments and/or additives may be used to control powder flow and charge distribution. Each substrate layer may be a sheet-like structure comprising fibers held together by binder. The binder may include sodium silicate.
A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.

METHOD AND APPARATUS FOR AUTOMATED COMPOSITE-BASED ADDITIVE MANUFACTURING
An apparatus and method for the automated manufacturing of three-dimensional (3D) composite-based objects is disclosed. The apparatus comprises a material feeder, a printer, a powder system, a transfer system, and optionally a fuser. The method comprises inserting a stack of substrate sheets into a material feeder, transferring a sheet of the stack from the material feeder to a printer, depositing fluid on the single sheet while the sheet rests on a printer platen, transferring the sheet from the printer to a powder system, depositing powder onto the single sheet such that the powder adheres to the areas of the sheet onto which the printer has deposited fluid, removing any powder that did not adhere to the sheet, optionally melting the powder on the substrate, and repeating the steps for as many additional sheets as required for making a specified 3D object.
An additive manufacturing method and apparatus is described for the printing of three-dimensional (3D) objects. The approach is based on a composite-based additive manufacturing process, except it uses commercial printing methods to achieve even higher speed and throughput. By using the invention, a prototyping and/or production process may be completed in hours rather than months, and the risks and problems of molds is eliminated. There is substantial improvement in the number and type of geometries that can be produced compared to injection molding, and the range of materials is enlarged as are the material properties. The method involves printing a substrate having at least one sheet using a printing technology, and stacking or folding the at least one sheet to form multiple layers consistent with that formed by a 3D model. The printing step is done using a printing technology such as flexography, lithography, offset, gravure, waterless printing, and silkscreen.

A distributed heterogeneous or homogeneous file storage system divides logical responsibility for data from actual control of the data by using separate file and storage managers. Each file manager provides access to stored files and stores metadata associated with each of the files for which it is responsible. A file manager control component allocates responsibilities among file managers, assigns management responsibilities for individual files, and maintains a record of which files are assigned to each manager. Each storage manager is responsible for managing storage of files on data storage devices and maintains a record of the location of each stored file. A storage manager control component allocates responsibilities among storage managers, assigns responsibilities for individual files, and maintains a record of which files and storage devices are assigned to each manager. A client provides user access, initiates actions within the system, and implements a redundant data recovery and reconstruction scheme.

METHODS AND APPARATUS FOR THREE-DIMENSIONAL PRINTED COMPOSITES
A 3D object according to the invention comprises substrate layers infiltrated by a hardened material. The 3D object is fabricated by a method comprising the following steps: Position powder on all or part of a substrate layer. Repeat this step for the remaining substrate layers. Stack the substrate layers. Transform the powder into a substance that flows and subsequently hardens into the hardened material. The hardened material solidifies in a spatial pattern that infiltrates positive regions in the substrate layers and does not infiltrate negative regions in the substrate layers. In a preferred embodiment, the substrate is carbon fiber and excess substrate is removed by abrasion.
