Benefits of technology
The patent text describes a method of three-dimensional printing where a three-dimensional printer prints a layer of an object onto a surface that is not part of the printer, while the printer is in a first position. The printer then repositioned to a second position elevated above the first position and prints a second layer of the object onto the first layer. This method allows for faster and more efficient printing of three-dimensional objects.
Problems solved by technology
Unfortunately, 3D printing is much more complex than 2D printing and requires much more time to produce an object.
Objects that are printed at a fine level of detail or have significant size can take many hours to complete.

Embodiment Construction
[0019]One embodiment of the present invention provides a method of three-dimensional printing. The method comprises a three-dimensional printer printing a first layer of a three-dimensional object onto a surface that is not part of the three-dimensional printer, wherein the first layer is printed while a printing platform of the three dimensional printer is in a first position. The method further comprises the three-dimensional printer printing a first layer of a scaffold separate from the first layer of the three-dimensional object. The three-dimensional printer is autonomously repositioned to be supported on the scaffold in a second position elevated above the first position, and a second layer of the three-dimensional object is printed onto the first layer of the three-dimensional object while the printing platform is in the second position. Preferably, the three-dimensional printer will also print a second layer of the scaffold over the first layer of the scaffold while the prin...

Abstract
One embodiment of the present invention provides a method of three-dimensional printing. The method includes a three-dimensional printer printing a first layer of an object onto a surface that is not part of the three-dimensional printer, wherein the first layer is printed while a printing platform of the three dimensional printer is in a first position. The printer is autonomously repositioned in a second position elevated above the first position by being supported either on the three-dimensional object itself or on a scaffold printed separate from the object. The printer prints a second layer of the three-dimensional object onto the first layer of the three-dimensional object while the printing platform is in the second position. The printer may have a plurality of legs for controllably repositioning the printing platform.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 518,405 filed on Oct. 20, 2014, which application is incorporated by reference herein.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to methods and apparatus for three dimensional printing.[0004]2. Background of the Related Art[0005]Three-dimensional (3D) printing is a process of making a three-dimensional object from a digital model using an additive process, where successive layers of material are laid down over previous layers. The material may be a thermoplastic polymer filament that is heated and extruded through a narrow nozzle. In one type of three dimensional printer, the nozzle, the table supporting the material, or both is moved to control where the material is deposited. Other types of three dimensional printers may use alternative mechanisms to control the position of a nozzle for dispensing the material.[0006]3D printing ha...
