Abstract: A material drop ejecting three-dimensional (3D) object printer identifies a time lag error corresponding to a time lag in the response of printer components to component commands. The identified time lag error is provided to a slicer program that uses the identified time lag error to compensate for the time lag in the response of the printer components.

Abstract: A slicer in a material drop ejecting three-dimensional (3D) object printer generates machine ready instructions that operate components of a printer, such as actuators and an ejector having at least one nozzle, to form features of an object more precisely than previously known. The instructions generated by the slicer use positional data from an encoder to control the actuators to move the ejector and a platform on which the object is formed relative to one another to form edges of the feature.

Abstract: A system for determining a temperature of an object includes a three-dimensional (3D) printer configured to successively deposit a first layer of material, a second layer of material, and a third layer of material to form the object. The 3D printer is configured to form a recess in the second layer of material. The material is a metal. The system also includes a temperature sensor configured to be positioned at least partially with the recess and to have the third layer deposited thereon. The temperature sensor is configured to measure a temperature of the first layer of material, the second layer of material, the third layer of material, or a combination thereof.

Abstract: An apparatus is disclosed. For example, the apparatus includes a paper feed to feed print media a single sheet at a time, a plurality of rotating discs, wherein each one of the plurality of rotating discs comprises an elastomer ring to secure a leading edge of the single sheet against a registration wall and initiate a flipping process, a curved baffle positioned above the plurality of rotating discs and the single sheet, an air duct located above the plurality of rotating discs and the single sheet to force an air flow towards the curved baffle, wherein the air flow follows a shape of the curved baffle to create a low pressure zone above the single sheet to keep a trailing edge of the single sheet levitated during completion of the flipping process, and a movable platform to hold a stack of the print media.

Abstract: A method of three-dimensional printing comprises heating a first portion of a build surface on a platform by impinging a laser beam on the build surface so as to provide a preheated drop contact point having a first deposition temperature. A first drop of a liquid print material is ejected from a printhead of a 3D printer so as to deposit the first drop on the preheated drop contact point at the first deposition temperature.

Abstract: A system for producing three-dimensional objects forms fluid paths within the support structure to facilitate the removal of the support structure following manufacture of the object. The system includes a first ejector configured to eject a first material towards a platen to form an object, a second ejector configured to eject a second material towards the platen to form support for portions of the object, at least one portion of the support having a body with at least one fluid path that connects at least one opening in the body to at least one other opening in the body, and a fluid source that connects to the at least one fluid path of the support to enable fluid to flow through the at least one fluid path to remove at least an inner portion of the support from the object.

Abstract: A method operates a three-dimensional object printer for production of cylindrical-shaped objects. The method uses a controller to operate an actuator operatively connected to a cylindrical member to rotate the cylindrical member within at least two supports, operate at least two printheads supplied with different materials to form portions of layers on the rotating cylindrical member with the different materials supplied to the at least two printheads, and operate at least one other actuator operatively connected to the at least two printheads and a curing device to move each of the printheads and the curing device independently of one another in a bidirectional radial direction with reference to a center of the rotating cylindrical member. This operation enables the curing device to be positioned to modify the layers formed on the rotating cylindrical member while the cylindrical member is rotating within the at least two supports.
