    Abstract: A tow stabilization method includes applying liquid to a tow having fibers arranged into a non-stabilized spread-out fiber web, applying powder to the web to adhere the powder where liquid was applied, removing powder from where it did not adhere, and fusing the powder remaining on the web to stabilize the fiber arrangement. The liquid may be volatile. The step of fusing may include heating the fiber web. The liquid and/or powder may be selectively applied. Selective application of powder may be used without application of liquid or powder removal. A tow stabilization apparatus includes a liquid applicator, powder applicator, powder remover, and powder fuser. The liquid applicator may include spray nozzles, applicators based on miniature solenoid valves, inkjet printing heads, and roll applicators. The powder remover may include rollers, air blasters, vibrators, sound wave generators, and vacuums. The powder fuser may include heat applicators and chemical reaction initiators.

    Abstract: A method/system of mechanical holdowns allows a substrate sheet in a CBAM (composite-based additive manufacturing technology) process to lie flat during printing. The invention includes a process of mechanically clamping sheets to be printed by a print head to a flat platen using a set of barrel cam driven clamping fingers. The finger supports are attached to the platen and the fingers can be raised and lowered with respect to the platen. Each finger can rotate while swinging downward toward a sheet at the edge of the platen. To clamp the sheet, the fingers are rotated to the perpendicular position and swung lower down to pinch the sheet to the platen. The process can include additional steps that release some, but not all, of the fingers to allow the sheet to relax before re-clamping them.

    Abstract: 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.
