Abstract

A system for printing a three-dimensional object is provided. The system can include at least one print head configured to receive a continuous fiber and at least partially encase the continuous fiber with a formation material to create a composite material. The at least one print bed can be configured to move in at least six different degrees of freedom. The system can also include at least one print bed comprising a printing surface onto which the composite material may be selectively applied to form a work piece. The at least one print head can be positioned relative to the at least one print bed and configured to advance print media thereon.

First claim

What is claimed is:

1. A system for printing a three-dimensional object, the system comprising:
at least one print head configured to receive a continuous fiber and at least partially encase the continuous fiber with a formation material to create a composite material;
at least one print bed comprising a printing surface onto which the composite material may be selectively applied to form a work piece; and
a movable arm with at least one mandrel positioned thereon for receiving the composite material and providing a form for shaping of the composite material into a selected shape on the print bed, and wherein the movable arm is in direct contact with the print bed.

2. The system according to claim 1 , further comprising:
a drive means associated with said at least one print head for advancing the continuous fiber through the at least one print head for application with the formation material.

3. The system according to claim 1 , wherein the continuous fiber is advanced through the at least one print head by pulling of the composite material via a connection of the composite material with one or more of a printing surface of the at least one print bed, the mandrel, and/or an existing work piece.

4. The system according to claim 1 , wherein said at least one print bed is configured to move in at least six different degrees of freedom, and said system further comprising:
one or more drive means connected to said at least one print bed for movement of the at least one print bed in one or more of the six different degrees of freedom; and
a controller in communication with said one or more drive means.

5. The system according to claim 1 , wherein the at least one print bed is movable along x, y, z coordinate planes and rotatable about pitch, row, and yaw axes.

6. The system according to claim 1 , wherein the print bed includes a receiver directly connected to the arm.

7. The system according to claim 1 , wherein the arm includes a rotation ball directly coupled to a receiver.

8. A system for printing a three-dimensional object, the system comprising:
at least one print bed comprising a printing surface onto which print media is applied to form a work piece, wherein said at least one print bed is configured to move in at least six different degrees of freedom;
at least one print head positioned relative to said at least one print bed and configured to advance print media thereon;
a movable arm having an end thereof in direct contact with the print bed; and
at least one mandrel positioned on the movable arm, for receiving the composite material and providing a form for shaping of the composite material into a selected shape on the printing surface of the at least one print bed.

9. The system according to claim 8 , further comprising:
one or more drive means connected to said at least one print bed for movement of the at least one print bed in one or more of the six different degrees of freedom; and
a controller in communication with said one or more drive means.

10. The system according to claim 8 , wherein the at least one print bed is movable along x, y, z coordinate planes and rotatable about pitch, row, and yaw axes.

11. The system according to claim 8 , wherein said at least one print head is configured to receive a continuous fiber and at least partially encase the continuous fiber with a formation material to create a composite material.

12. The system according to claim 11 , further comprising:
a drive means associated with said at least one print head for advancing the continuous fiber through the at least one print head for application to the printing surface of the at least one print bed.

13. The system according to claim 11 , wherein the continuous fiber is advanced through the at least one print head and onto the printing surface of the at least one print bed by pulling of the composite material via a connection of the composite material with the printing surface of the at least one print bed.

14. The system according to claim 8 , wherein the print bed includes a receiver directly connected to the arm end.

15. The system according to claim 1 , wherein the arm includes a rotation ball directly coupled to a receiver.
