Abstract
A system for fabricating an object includes an extruder for one or more deposition materials. The extruder has at least one nozzle with a nozzle tip that includes an exit orifice and has a width that is equal to or larger than a width of the exit orifice. The system also includes a controller coupled with the extruder, the controller configured to apply a correction factor that has been calculated for a path of the nozzle based on a slope of a surface of an object to be fabricated. The correction factor for a positive slope is different from that for a negative slope. The extruder is configured to cause movement of the nozzle along the path to deposit material on the slope of the surface of the object, and the correction factor removes differences in thickness of the deposited material caused by the slope in relation to the path.
