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： A method of residual ink removal in an ink-dependent 3-D printing process includes pre-heating a build block to an evaporation temperature. This is preferably done after stacking and before compression. Later compression will then involve a higher temperature to allow fusing of thermoplastic material in the build block, but without residual ink.

摘要： A three-dimensional object comprises substantially planar or flat substrate layers that are folded and stacked in a predetermined order and infiltrated by a hardened material. The object is fabricated by positioning powder on all or part of multiple substrate layers. On each layer, the powder is selectively deposited in a pattern that corresponds to tiles that each have a slice of the object. For each slice, powder is deposited in positions that correspond to positions in the slice where the object exists, and not deposited where the object does not exist. The tiles of each substrate layer are folded and aligned in a predetermined order. Multiple folded substrate layers mat be combined into a single stack. The powder 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.

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： 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 a non-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.

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： 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.
