Abstract: Aspects of the disclosure relate to a method for creating a solidified material using a machine tool. In some aspects, the machine tool supplies a current to an induction coil such that the induction coil generates a magnetic field. The machine tool changes the magnetic field to induce eddy currents in a first conductor surrounding a feedstock and a second conductor surrounded by the feedstock. The machine tool uses the eddy currents to cause the feedstock to transition from a solid state to a uniform malleable state regardless of the feedstock's electrical conductivity.

Abstract: A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.

Abstract: Disclosed herein are solution-based additive manufacturing inks comprising a polymer, a volatile solvent compound, and a nonsolvent compound.
