Abstract: Methods for removing support structures in additively manufactured parts are disclosed. A method in accordance with an aspect of the present disclosure comprises inserting a demolition object in a first state into a hollow portion of a 3-D printed part, breaking a support structure within the hollow portion by contact with the demolition object, changing the demolition object into a second state while the demolition object is within the hollow portion of the 3-D printed part, and removing the demolition object from the hollow portion of the 3-D printed part.

Abstract: A roll-to-roll computed axial lithography system includes an optical illumination system; an optical modulation system to receive light from the optical illumination system and to output an illumination pattern of light; and a web-handling system to receive and transport a web having a photosensitive material layer such that a portion of the web will be in an optical path of the modulation system. The web-handling system includes a development module to render three-dimensional structures from the layer exposed to the illumination pattern of light. The illumination pattern of light provides predetermined three-dimensional regions within a bulk of the layer that are exposed beyond a photo-responsive threshold for the photosensitive material providing volumetric patterning. The development module removes one of regions of the layer exposed beyond the photo-responsive threshold or regions of the layer that are not exposed beyond the photo-responsive threshold to provide a three-dimensional structure from the layer.

Abstract: An additive manufacturing method, an additive manufacturing system (1200), a support material for additive manufacturing, an assembly of the support material and a structure material, and a product thereof are provided. The method comprises depositing, by a nozzle (1210a), a structure material into a support material based on a computer model of an object, thereby forming a portion of the object. Image data of at least the portion of the object can be obtained in-process by a detector (1240). The image data is compared to the computer model. Based on the comparison, the method can comprise modifying the computer model, modifying a print parameter, modifying machine path instructions for an additive manufacturing machine that comprises the nozzle, aborting the additive formation, indicating a discrepancy, indicating validation of the shape, or a combination thereof. The depositing of the structure material is repeated by the nozzle (1210a) as necessary to additively form the object.
