摘要： 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.

摘要： 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.

摘要： 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.

摘要： A 3D object (the “New Object”) is fabricated layer by layer by 3D printing. The shape and relative dimensions of the various parts of the New Object match that of another 3D object (the “Target Object”). In addition, the exterior of the New Object appears to be a photographic likeness of the Target Object. The “photographic” likeness is created by variations in visual characteristics of materials in the layers comprising the New Object, and in particular by variations at or near the surface of the New Object. Thus, the photographic likeness is an integral part of these layers comprising the New Object. An object is scanned, from which a texture map is obtained. A CAD model is sliced into slices (bit maps files) which are then colored by a program with the boundary to match the color or gray scale to color the appropriate pixels, derived from the texture map.

摘要： A method and apparatus for resistive heating usable in composite-based additive manufacturing is disclosed. The method includes providing a prepared stack of substrate sheets, placing the stack between electrode assemblies of a compression device, applying a current to thereby heat the stack to a final temperature to liquefy applied powder, compressing the stack to a final height, cooling the stack, and removing the cooled, compressed stack from the compression device. The apparatus comprises at least two plates, a power supply for providing current, a first electrode assembly and a second electrode assembly.

摘要： 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.

摘要： 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.

摘要： A 3D object according to the invention involves substrate layers infiltrated by a hardened material. The 3D object may be fabricated by a method comprising the following steps: Flatten a substrate layer. 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.
