Abstract

A method comprising building at least one three-dimensional model and a support structure using a layer-based additive technique, where the at least one three-dimensional model is at least partially encased in the support structure, and where the support structure functions as a shipping package for the at least one three-dimensional model.

Claims

1. A method of building and using a support structure, the method comprising:

receiving a digital representation of a three-dimensional model;

generating a first digital representation of the support structure based on at least one overhanging region of the digital representation of the at least one three-dimensional model; and

generating a second digital representation of the support structure based at least in part on dimensions of the digital representation of the at least one three-dimensional model;

building the three-dimensional model using a layer-based additive technique;

building the support structure using the layer-based additive technique such that the built support structure at least partially encases the at least one three-dimensional model; and

shipping the at least one built three-dimensional model while at least partially encased in the built support structure.

2. The method of claim 1, wherein the support structure is built such that the built support structure fully encases the at least one built three-dimensional model.

3. The method of claim 1, wherein the second digital representation of the support structure is generated based at least in part on a predetermined offset distance from at least one exterior surface of the digital representation of the at least one three-dimensional model.

4. The method of claim 1, and further comprising building a shipping label on an exterior surface of the support structure using the layer-based additive technique.

5. The method of claim 1, and further comprising removing the support structure from the at least one three-dimensional model after the shipping.

6. A method of building and using a support structure, the method comprising:

generating a first digital representation of the support structure based on at least one overhanging region of a digital representation of a three-dimensional model;

generating a second digital representation of the support structure based on dimensions of the digital representation of the three-dimensional model;

generating build data based at least in part on the digital representation of the three-dimensional model, the first digital representation of the support structure, and the second digital representation of the support structure;

building the three-dimensional model and the support structure with a digital manufacturing system using a layer-based additive technique based on the build data such that the built support structure at least partially encases the three-dimensional model; and

shipping the built three-dimensional model while at least partially encased in the built support structure.

7. The method of claim 6, wherein the support structure is built such that the built support structure fully encases the built three-dimensional model.

8. The method of claim 6, and further comprising receiving the digital representation of the three-dimensional model.

9. The method of claim 6, and further comprising:

receiving shipping information from the customer;

generating a digital representation of a shipping label, wherein the generated build data is further based on the digital representation of the shipping label; and

building the shipping label on the support structure with the digital manufacturing system based on the build data.

10. The method of claim 6, wherein the digital manufacturing system comprises a deposition-based digital manufacturing system selected from the group consisting on an extrusion-based system, an ink jetting system, and combinations thereof.

11. The method of claim 6, wherein the support structure is built from a support material selected from the group consisting of a water-soluble support material, a break-away support material, and combinations thereof.
