Title:
CROSS LAYER FIBER ENTANGLEMENT TO INCREASE STRENGTH OF 3D PART
Document Type and Number:
Japanese Patent JP2020165072
Kind Code:
A
Abstract:
To provide systems and methods for composite-based additive manufacturing, and more particularly, to provide such process that render individual laminate layers to be built up to form and/or manufacture three-dimensional objects, parts and components (3D objects).SOLUTION: There is provided a printed sheet fiber entanglement apparatus, in which while a stack 138 of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. An array of needles with upward and/or downward facing barbs is thrust through holes in the guide plate into the stack through printed sheets closest to the guide plate. As barbs on the felting needles intertwine fibers from the fibrous sheets 132 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.SELECTED DRAWING: Figure 1
