Abstract

A universal adapter for use with a consumable assembly that is configured for use with an additive manufacturing system, the universal adapter comprising an inlet opening configured to receive a guide tube of the consumable assembly, and a connection member at the outlet end, which is configured interface with a mating panel of the additive manufacturing system.

Claims

1. A consumable assembly for use with an additive manufacturing system having a print head and a mating panel that is disposed at remote location from a print head, the consumable assembly comprising:

a container portion having a supply of a consumable filament;

a flexible guide tube having a first end disposed in the container portion and a second end; and

a universal adapter that is separate from the container portion, and comprising;

an inlet opening through which the second end of the guide tube extends;

a coupling mechanism configured to secure the universal adapter to the mating panel;

an outlet orifice configured to engage a reciprocating opening of the mating panel; and

a filament drive mechanism engaged with a segment of the consumable filament that is fed from the container portion, through the guide tube, and into the universal adapter, wherein the filament drive mechanism is configured to relay the consumable filament from the outlet orifice of the universal adapter and into the reciprocating opening of the mating panel.

2. The consumable assembly of claim 1, and further comprising a first electrical contact configured to engage a second electrical contact of the mating panel.

3. The consumable assembly of claim 2, wherein the filament drive mechanism is electrically connected to the first electrical contact, and wherein the first electrical contact is configured to relay electrical power from the additive manufacturing system to the filament drive mechanism.

4. The consumable assembly of claim 1, wherein the filament drive mechanism comprises a motor and a capstan drive shaft operably rotated by the motor, wherein the capstan drive shaft is the portion of the filament drive mechanism that is engaged with the segment of the consumable filament.

5. The consumable assembly of claim 1, wherein the universal adapter further comprises an adapter housing, and wherein the filament drive mechanism is retained within the adapter housing.

6. The consumable assembly of claim 1, wherein the supply of the consumable filament is retained in the container portion in a figure-8 coil configuration.

7. The consumable assembly of claim 6, wherein the container portion comprises a liner, and wherein the supply of the consumable filament is disposed within the liner.

8. The consumable assembly of claim 1, wherein the supply of the consumable filament is retained in the container portion in a spooled manner.

9. A consumable assembly for use with an additive manufacturing system having a print head and a mating panel that is disposed at remote location from a print head, the consumable assembly comprising:

a container portion configured to retain a supply of a consumable filament;

an adapter that is separate from the container portion, and comprising;

an adapter housing having an inlet end and an outlet end;

an inlet opening at the inlet end configured to receive the consumable filament from the container portion;

a coupling mechanism at the outlet end configured to secure the adapter to the mating panel; and

an outlet orifice at the outlet end configured to engage a reciprocating opening of the mating panel, and further configured to relay the consumable filament from the adapter and into the reciprocating opening of the mating panel.

10. The consumable assembly of claim 9, and further comprising a flexible guide tube having a first end disposed in the container portion and a second end extending into the inlet opening of the adapter.

11. The consumable assembly of claim 9, wherein the adapter further comprises a filament drive mechanism configured to engage with the consumable filament in the adapter.

12. The consumable assembly of claim 9, wherein the adapter further comprises a first electrical contact at the outlet end configured to engage a second electrical contact of the mating panel.

13. The consumable assembly of claim 9, wherein the supply of the consumable filament is retained in the container portion in a figure-8 coil configuration.

14. A consumable assembly for use with an additive manufacturing system having a print head and a mating panel that is disposed at remote location from a print head, the consumable assembly comprising:

a consumable filament retained in a figure-8 coil configuration and having a payout hole;

a payout tube disposed in the payout hole;

a flexible guide tube having a first end at the payout tube and a second end;

an adapter comprising;

an adapter housing having an inlet end and an outlet end;

an inlet opening at the inlet end, wherein the second end of the guide tube extends into the inlet opening;

a coupling mechanism at the outlet end configured to secure the adapter to the mating panel; and

an outlet orifice at the outlet end configured to engage a reciprocating opening of the mating panel, and further configured to relay the consumable filament from the adapter and into the reciprocating opening of the mating panel.

15. The consumable assembly of claim 14, and further comprising a liner, wherein the consumable filament retained in the figure-8 coil configuration and the payout tube are sealed in the liner.

16. The consumable assembly of claim 15, and further comprising a container, wherein the liner, the consumable filament retained in the figure-8 coil configuration, and the payout tube are retained in the container.

17. The consumable assembly of claim 15, and further comprising desiccant retained within the liner.

18. The consumable assembly of claim 14, and further comprising a first electrical contact configured to engage a second electrical contact of the mating panel.

19. The consumable assembly of claim 14, and further comprising a filament drive mechanism engaged with the consumable filament in the universal adapter.

20. The consumable assembly of claim 19, wherein the filament drive mechanism is configured to receive electrical power from the additive manufacturing system.
