Additive manufacturing technique for printing three-dimensional parts with printed receiving surfaces
First Claim
Patent Images
1. A method for printing three-dimensional parts with an additive manufacturing system, the method comprising:
- printing successive layers along a printing axis onto a first receiving surface of a print foundation, wherein the printed successive layers have increasing cross-sectional areas parallel to a build plane that is normal to the printing axis, wherein a last layer of the printed successive layers defines a second receiving surface;
printing layers of a three-dimensional part onto the second receiving surface, wherein the last layer of the printed successive layers has a first cross-sectional area parallel to the build plane, wherein a first layer defines of the three-dimensional part has a second cross-sectional area parallel to the build plane, and wherein the first cross-sectional area is at least as large as the second cross-sectional area; and
print the three dimensional part to a dimension greater than the additive manufacturing system by indexing a platen gantry extendable out of a port of the additive manufacturing system.

Abstract
A method for printing three-dimensional parts with an additive manufacturing system, comprising printing successive layers having increasing cross-sectional areas, and printing layers of a three-dimensional part onto the previously printed layers, where a last layer of the previously printed successive layers has a cross-sectional area that is at least as large as a footprint area of the three-dimensional part.

9. A method for printing three-dimensional parts with an additive manufacturing system, the method comprising:
-
providing a first cross-sectional area of a receiving surface parallel to a build plane; providing a footprint area of a three-dimensional part parallel to the build plane; generating tool paths for successive layers that increase in cross-sectional areas parallel to the build plane from the first cross-sectional area to at least the footprint area of the three-dimensional part; printing the successive layers with the additive manufacturing system onto the receiving surface based on the generated tool paths; and printing a three-dimensional part onto the printed successive layers wherein a length of the three-dimensional part is greater than a length of the additive manufacturing system. - View Dependent Claims (10, 11, 12, 13)

14. A method for printing three-dimensional parts with an additive manufacturing system, the method comprising:
-
printing a scaffold along a printing axis with the additive manufacturing system, wherein the printed scaffold comprises a plurality of successive wedge portions offset along the printing axis, and wherein each wedge portion has a receiving surface with a cross-sectional area parallel to a build plane that is normal to the printing axis; and printing a three-dimensional part onto each printed receiving surface, such that each three-dimensional part is associated with one of the receiving surfaces, wherein each three-dimensional part has a cross-sectional area parallel to the build plane that is less than or equal to the cross-sectional area of its associated receiving surface. - View Dependent Claims (15, 16, 17, 18, 19, 20)
