SYSTEMS AND METHODS FOR IMPROVED 3D PRINTING
First Claim
1. A system for fabricating an object, the system comprising:
- an extruder for one or more deposition materials, the extruder comprising at least one nozzle having a nozzle tip that includes an exit orifice, the tip having a width that is equal to or larger than a width of the exit orifice; and
a controller coupled with the extruder, the controller configured and arranged 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 being different from the correction factor for a negative slope;
wherein the extruder is configured and arranged to cause movement of the nozzle along the path to deposit a 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.

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.

18. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers, which, upon such execution, cause the one or more computers to perform operations for controlling a 3D printer, the 3D printer comprising an extruder for one or more deposition materials, the extruder comprising at least one nozzle having a nozzle tip that includes an exit orifice, the tip having a width that is equal to or larger than a width of the exit orifice, the operations comprising:
-
applying 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, wherein the correction factor for a positive slope is different from the correction factor for a negative slope; and causing movement of the nozzle along the path to deposit a material on the slope of the surface of the object, wherein the correction factor removes differences in thickness of the deposited material caused by the slope in relation to the path. - View Dependent Claims (19)
