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.

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.

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.

A saliva collector comprises a reservoir, a bubble barrier, and a membrane, where the bubble barrier and membrane are arranged in tandem on a flow path from an inlet to an outlet on the reservoir. Air aspirated from a patient's oral cavity enters the reservoir through the inlet, passes through the bubble barrier to remove foam and bubbles, passes through the membrane to remove entrained liquid saliva, and passes out through the outlet.

An oral appliance is sized by obtaining a scaled image of a patient's dental arch. Dimensions of the arch are marked on a screen image, and the processor chooses an oral appliance having a best fit for a particular patient.

Screen-based method and system for sizing an oral appliance

A system for sizing an oral appliance includes a right overlay, a left overlay, and a wax bite plate. A dental arch impression of a patient is taken on the wax bite plate, and indicia on the right and left overlays are aligned with the dental arch impression to provide information on both the arcuate shape and width of an oral appliance which can best fit the patient.

Method and system for sizing an oral appliance using overlays

Systems for sizing oral applications include both a width measuring template or tool for determining the distance between opposed molars and an arch sizing tool for determining the size and shape of the patient's dental arch. Based on this information, individual appliances can be selected from an inventory of such appliances, where the selected appliance would best fit the patient.
