Abstract

A print head is disclosed for use with an additive manufacturing system. The print head may include a matrix reservoir, and a nozzle base connected to an end of the matrix reservoir. The nozzle base may have a plurality of attachment features formed within an exposed surface. The print head may further include a plurality of available dies separately connectable to the nozzle base via the plurality of attachment features. Attachment of the plurality of available dies to the nozzle base may establish fluid communication with the matrix reservoir.

First claim

What is claimed is:

1. A die for a print head of an additive manufacturing system, the die comprising:
a nozzle base;
a plurality of wall blocks separately connectable to the nozzle base in a plurality of available configurations to form an open-ended enclosure configured to shape material discharging from the print head; and
at least one orifice block connectable to the base at a location inside the open-ended enclosure and configured to discharge the material into the open-ended enclosure.

2. The die of claim 1 , further including at least one cure block located at a periphery of the open-ended enclosure and configured to expose the material after discharge to energy that causes the material to cure.

3. The die of claim 2 , wherein at least one of a location and a number of the at least one cure block is adjustable.

4. The die of claim 2 , wherein the at least one cure block hosts at least one cure enhancer configured to enhance curing of a matrix discharging from the print head.

5. The die of claim 4 , wherein the at least one cure enhancer is a UV light.

6. The die of claim 1 , wherein the one of the plurality of available configurations of the open-ended enclosure is adjustable via movement of the plurality of separate wall blocks relative to the base.

7. The die of claim 1 , wherein at least one of a location and a number of the at least one orifice block is adjustable.

8. The die of claim 1 , wherein the plurality of wall blocks and the at least one orifice block each includes an attachment feature configured to removably engage a corresponding attachment feature of the base.

9. A print head of an additive manufacturing system, the print head comprising:
a matrix reservoir;
a nozzle base fluidly connected to an end of the matrix reservoir and having a plurality of attachment features formed within an exposed surface;
a plurality of wall blocks separately connectable to the nozzle base via the plurality of attachment features in a plurality of different configurations, the plurality of wall blocks arranged to form an open-ended enclosure together that shapes material discharging from the print head.

10. The print head of claim 9 ,
further including at least one orifice block located inside the open-ended enclosure and configured to discharge the material, wherein attachment of the at least one orifice block to the nozzle base establishes fluid communication with the matrix reservoir.

11. The print head of claim 10 , further including at least one cure block mounted on the nozzle base in a plurality of adjustable configurations at a periphery of the open-ended enclosure and configured to expose the material after discharge to energy that causes the material to cure.

12. The print head of claim 11 , wherein mechanical attachment of the at least one cure block to the nozzle base establishes at least one electrical connection.

13. The print head of claim 9 , wherein the the open-ended enclosure is connectable to the nozzle base at different locations.

14. The print head of claim 9 , wherein multiple open-ended enclosures may be connected to the nozzle base at the same time to form a multi-part die assembly.

15. A print head of an additive manufacturing system, the print head comprising:
a matrix reservoir;
a nozzle base connected to an end of the matrix reservoir and having a plurality of attachment features formed within an exposed surface; and
a plurality of wall blocks separately connectable to the nozzle base in a plurality of different configurations via the plurality of attachment features to form an open-ended enclosure that shapes material as it discharges from the print head; and
at least one orifice block connectable to the nozzle base via at least one of the plurality of attachment features at a location inside the open-ended enclosure, wherein attachment of the at least one orifice block to the nozzle base establishes fluid communication with the matrix reservoir.

16. The print head of claim 15 , further including at least one cure block connectable to the nozzle base via at least one of the plurality of attachment features at a periphery of the open-ended enclosure.

17. The print head of claim 16 , wherein attachment of the at least one cure block to the nozzle base establishes at least one electrical connection.

18. The print head of claim 16 , wherein at least one of the following is adjustable:
a location of the at least one cure block;
a number of the at least one cure block;
a configuration of the open-ended enclosure;
a location of the at least one orifice block; and
a number of the at least one orifice block.

19. The print head of claim 16 , wherein the at least one cure block hosts at least one cure enhancer configured to expose the material after discharge to energy to enhance curing of a matrix discharging from the print head.

20. The print head of claim 19 , wherein the at least one cure enhancer is a UV light.
