Abstract
An additive manufacturing system for fabricating multi-sided printed composite sheet structures includes a roll fed duplex architecture that prints polymer images on both sides of a substrate sheet to form two-sided 3D composite layers. A substrate web is fed into the machine, and a top side is printed with a wetting agent, powdered, and the excess powder is removed. The image may be pinned to the substrate in a fusing step so that the web can be inverted to print a second image on the other side. The inversion architecture could include inverting rollers, tubes or a Mobius strip that may flip the substrate for backside printing using a single imaging station. The resulting two-side powdered and pinned substrate would then be cut, stacked, heated and compressed to create a 3-D object with more polymer in the stack, resulting in better adhesive binding characteristics at a much higher production speed.
