Abstract: Methods, systems, and computer programs for multi-tool additive manufacturing include a method including: slicing a received model into a series of layers; determining one or more separation starting points, each being a location of two adjoining portions of the model that are to be manufactured by respective additive manufacturing robots; and determining an offset for each of the one or more separation starting points in each layer of the series of layers based on a threshold acceptable print time, each offset in a layer determining a seam location in the layer that is different from a seam location in at least one adjacent layer in the series of layers, and seam offsets determined for the series of layers increase an estimated print time, for manufacturing of the series of layers by the two or more additive manufacturing robots, to no more than the threshold acceptable print time.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a multi-tool additive manufacturing system that executes in a three-dimensional build volume. In one aspect, a system includes a build platform; a support; a first robot coupled with the support and configured to operate in a build volume defined by the build platform, wherein the first robot includes a first additive manufacturing tool; a second robot coupled with the support and configured to operate in the build volume, wherein the second robot includes a second additive manufacturing tool; wherein the first robot and the second robot are programmed to coordinate simultaneous application; and wherein a first tool path of the first additive manufacturing tool in the first region abuts or overlaps with a second tool path of the second additive manufacturing tool in the second region so as to form a bond.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for reducing or eliminating curl and wrap in additive manufacturing include, in at least one aspect, obtaining a three dimensional (3D) model of a 3D object to be additively manufactured using a thermoplastic material delivery apparatus; generating a variable width brim for at least a first layer of the 3D model, wherein a width of the brim varies from a maximum value to a minimum value at different locations adjacent at least the first layer of the 3D model, and the generating comprises varying the width of the brim in accordance with an amount of convexity of the 3D model in regions corresponding to the different locations; and outputting the variable width brim for use in preventing warping during the additive manufacturing of the object from the 3D model using the thermoplastic material delivery apparatus.

Abstract: A system, method, and computer program for remotely viewing video or still images from one or more cameras on a customer network, providing real-time feedback on focus adjustments made by an operator. The system may include a security bridge device plugged into the customer network and a portable electronic device remotely located from the security bridge device. The security bridge device may auto-negotiate network settings with the customer network, automatically discover the cameras on the customer network, automatically/manually address and configure the cameras, and/or automatically/manually determine a best path for transmitting the video or still images. The portable electronic device may receive and display the video or still images from the cameras transmitted by the security bridge device via the determined best path. This allows the operator to focus one of the cameras while viewing the real-time video or still images therefrom.
