Abstract: A method for 3D printing a part in a layer-wise manner includes providing a pool of polymerizable liquid in a vessel over a build window and positioning a downward-facing build platform in the pool, thereby defining a build region above the build window. The method includes selectively curing a volume of polymerizable liquid in the build region by imparting electromagnetic radiation through the build window to form a printed layer of the part adhered to the build platform and scanning at least a portion of the build window with monochromatic, polarized light along a plane of incidence. The method includes measuring a change in intensity and polarity of the light to obtain information about the printed layer. The method includes raising the build platform to a height of a next layer to be printed and modifying the electromagnetic energy imparted into the next layer based upon the obtained information to print a next layer. The imparting, scanning, measuring, raising and modifying steps are repeated until the part is printed.

Abstract: A large-scale additive manufacturing system for printing a structure includes an extrusion system and a knitting system. The extrusion system includes a nozzle configured to receive a supply of structural material and to selectively dispense the structural material in flowable form, and a first gantry configured to move the nozzle along toolpaths defined according to a structure to be printed such that structural material may be dispensed along the toolpaths to print a series of structural layers, wherein the series of structural layers bond together to form all or a portion of the structure. The knitting system includes a tow feeder configured to feed a supply of tow material to a location proximate a current course of loops extending above an upper surface of a current structural layer or extending above a base surface in regions where no structural layer has been printed, and a hooking device configured to engage the tow material and bring it through the current course of loops to form a subsequent course of loops interwoven with the current course of loops. A controller is configured to operate the knitting system to form additional subsequent courses of loops each interwoven with a current course of loops after each of the series of structural layers are printed, wherein the interwoven courses of loops create a reinforcement network of knitted loops embedded in the structure, and wherein the series of structural layers are tied together.
