Three-dimensional printer having an expandable envelope |
| 摘要 |
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. |

1. A method, comprising:
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 three-dimensional printer printing a first layer of a scaffold separate from the first layer of the three-dimensional object; autonomously repositioning the three-dimensional printer to be supported on the scaffold in a second position elevated above the first position; and printing 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. |
