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: Exemplary printing apparatuses include, among other components, a printhead structure that includes nozzles adapted to eject liquid ink, a carriage assembly having positioning structures, and one or more printhead caps or cups within the carriage assembly. The carriage assembly is shaped to latch to the printhead structure. The printhead includes corresponding structures and the positioning structures engage with the corresponding structures when the carriage assembly is latched to the printhead structure. Also, the printhead caps are positioned within the carriage assembly so as to cover the nozzles when the carriage assembly is connected to the printhead structure.

Abstract: A method of manufacturing a three-dimensional object is disclosed. The method includes operating a first ejector of a three-dimensional object printer to eject a first material towards a platen to form an object. The method further includes operating a second ejector of the three-dimensional object printer to eject a second material towards the platen to form support for portions of the object, the support being configured to provide support for portions of the object during the operation of the first ejector to form 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. The method further includes connecting a fluid source 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 the support from the object.

Abstract: A method of manufacturing a three-dimensional object facilitates the removal of support material from the object. The method includes moving the object to a position opposite a microwave radiator and operating the microwave radiator to change the phase of the support material from solid to liquid. A controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated. The microwave radiation does not damage the object because the support material has a dielectric loss factor that is greater than the dielectric loss factor of the object.

Abstract: A three-dimensionally printed object includes build portions formed with a build material, first support portions formed with a first support material, and second portions formed with a second support material that is different than the first support material. The first and second support portions are arranged with the build portions such that the build portions are supported and protected during fabrication of the object. The arrangement is optimized to minimize a time period for removing the first and second support materials from the object and releasing the build portions. A method of producing the object includes operating ejectors of a three-dimensional object printer to form the build portion, first support portions, and the second support portions. The portions are formed with reference to the arrangement.

Abstract: A system uses microwave energy to remove support material from a three-dimensional printed object with reduced risk of damage to the object. The system includes a microwave source, a three port device, a susceptor, a temperature sensor, and a controller. The controller operates the microwave source to direct microwave energy into a first port of the three port device, which emits the microwave at a second port of the three port device to irradiate the three-dimensional object and melt the support material. Reflected microwave increases as the amount of support material contacting the object is reduced and enters the second port of the three port device, which directs the reflected energy to the susceptor coupled to a third port of the three port device. The controller monitors the signal generated by the temperature sensor and deactivates the microwave source in response to a predetermined condition being reached.
