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 system for manufacturing a three-dimensional object facilitates the removal of support material from the object. The system includes a controller configured to move a platen to position the object at a position opposite a microwave radiator and then operate the microwave radiator to change the phase of the support material from solid to liquid. The 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 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.
