摘要： A platen for a 3D printer apparatus contains tab pairs for the winding of a single wire to form the platen surface after being wound back and forth across its length. Punch backs for hole punching onto such a sheet exist on aluminum blocks that secure rails between which the platen is assembled onto the printer table top.

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 printer platen component of an apparatus for automated manufacturing of three-dimensional composite-based objects for printing onto substrate sheets. The platen solves two problems: 1) holding the sheet down without allowing it to move while printing; and 2) getting rid of excess printing fluid. The platen comprises a plate with a number of air channel openings used for suction to hold the sheet in place, a bed of wire used to suspend the sheet and to keep the sheet straight, a depressed reservoir where printing fluid accumulates, a number of punching holes, a number of screws which serve as release sites for the sheet and cooperate with tips of a gripper to transfer the sheet to the platen, and a rough surface to additionally help hold down the sheet and keep it from moving. The platen is connected to an air plenum resting underneath the main plate to provide the suction.

摘要： A method and powder system component of an apparatus for use in a printing process is disclosed, and for removing and recycling excess powder. The powder system results in a cutoff point of 3 microns rather than 50 microns of previous systems. The apparatus comprises a powder applicator, a powder remover, a helical cyclone, a powder collector, and two valves that alternately open and close. The two-valve system prevents air backflow. The powder is processed through the two-valve system. The method comprises: valve 1 is closed and powder accumulates; valve 2 is closed also; after valve 1 opens, powder goes through (there is no air backflow), then valve 1 closes; then valve 2 opens and allows powder onto a powder applicator; then valve 2 closes; then the cycle starts again.

摘要： A stacker component of an apparatus for automated manufacturing of three-dimensional composite-based objects for aligning registration of sheets. The stacker includes a sheet catcher; a frame having a base plate with the base plate having tapered registration pins to align a stack of substrate sheets. The registration pins are mounted in the base plate and project vertically to a location just below the sheet catcher. The stacker also has a presser with a press plate and a belt driver system that moves the press plate up and down allowing the press plate to exert downward pressure on the stack and a slide system with two guide rails that enable the base plate to be loaded and unloaded. A conveyor can be disposed so that after a substrate sheet exits a powder or printing system, the sheet is conveyed onto the sheet catcher.

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 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.
