Abstract

A three-dimensional (3D) object production system and methods for 3D printing reactive components to form a thermoset product. The disclosure relates to Use of a 3D printer having a controller comprising one or more processors to print a 3D object. The disclosure also provides a 3D object production system and methods for 3D printing comprising adjusting one or more parameters of an at least one actuator to produce a 3D object based on a reaction rate between reactive components.

Claims (56)

1. A three-dimensional (3D) object production method comprising:

providing an extruded thermoset printing apparatus comprising:

an extrusion nozzle to deliver a thermosetting material to form a 3D object, and

a mixing chamber to receive and mix at least a first reactive component and a second reactive component to provide the thermosetting material;

detecting an obstruction within the extruded thermoset printing apparatus;

removing the obstruction within the extruded thermoset printing apparatus; and

producing the 3D object based on a 3D object design using thermosetting material delivered by the extruded thermoset printing apparatus,

wherein the removing comprises purging the extrusion nozzle.

2. The method according to claim 1 , wherein detecting an obstruction within the extruded thermoset printing apparatus comprises analyzing one or more properties of the extruded thermoset printing apparatus to detect the obstruction.

3. The method according to claim 2 , wherein the extruded thermoset printing apparatus comprises one or more pumps to at least deliver each of the first reactive component and a second reactive component to the mixing chamber, wherein the one or more properties of the extruded thermoset printing apparatus comprises torque of the one or more pumps.

4. The method according to claim 1 , wherein the extruded thermoset printing apparatus comprises one or more flow meters to determine one or more of:

a first flow rate of the first reactive component to the mixing chamber,

a second flow rate of the second reactive component to the mixing chamber, and

an extrusion flow rate of the thermosetting material from the extrusion nozzle, wherein the one or more properties of the extruded thermoset printing apparatus comprises one or more of the first flow rate, the second flow rate, and the extrusion flow rate.

5. The method according to claim 1 , wherein the extruded thermoset printing apparatus comprises one or more pressure sensors to determine one or more of:

a mixing chamber pressure within the mixing chamber, and

an extrusion pressure within the extrusion nozzle, wherein the one or more properties of the extruded thermoset printing apparatus comprises one or more of the mixing chamber pressure and the extrusion pressure.

6. The method according to claim 1 , wherein the method comprises:

initiating a cleaning event in response to detection of an obstruction within the extruded thermoset printing apparatus.

7. A three-dimensional (3D) object production method comprising:

providing an extruded thermoset printing apparatus comprising:

an extrusion nozzle to deliver a thermosetting material to form a 3D object, and

a mixing chamber to receive and mix at least a first reactive component and a second reactive component to provide the thermosetting material;

producing the 3D object based on a 3D object design using thermosetting material delivered by the extruded thermoset printing apparatus; and

detecting one or more mixing properties based on the thermosetting material as the thermosetting material is delivered by the extruded thermoset printing apparatus,

wherein the extruded thermoset printing apparatus comprises

a color detector to detect a color of the thermosetting material as the thermosetting material is delivered by the extruded thermoset printing apparatus, wherein the one or more mixing properties comprises color detected by the color detector or

a chemical property detector to detect one or more chemical properties of the thermosetting material as the thermosetting material is delivered by the extruded thermoset printing apparatus, wherein the one or more mixing properties comprises the one or more chemical properties detected by the chemical property detector.

8. The method according to claim 7 , wherein the extruded thermoset printing apparatus comprises the color detector to detect a color of the thermosetting material as the thermosetting material is delivered by the extruded thermoset printing apparatus, wherein the one or more mixing properties comprises color detected by the color detector.

9. The method according to claim 8 , wherein the color detector comprises one or more of a photodetector, a photoresistor, a photodiode, and a phototransistor.

10. The method according to claim 7 , wherein the extruded thermoset printing apparatus comprises the chemical property detector to detect one or more chemical properties of the thermosetting material as the thermosetting material is delivered by the extruded thermoset printing apparatus, wherein the one or more mixing properties comprises the one or more chemical properties detected by the chemical property detector.

11. The method according to claim 10 , wherein the one or more chemical properties comprise at least one of urethane content, urea content, isocyanate content, and aromatic content.

12. The method according to claim 7 , wherein the method comprises:

determining whether quality of the thermosetting material is acceptable based on the detected one or more mixing properties; and

initiating a quality control event in response to determination that quality of the thermoset product is not acceptable.

13. The method according to claim 12 , wherein the quality control event comprises one or more of a quality control notification to notify the user of the unacceptability of the thermosetting material and a delay process to allow for the quality of thermosetting material to improve.

14. The method according to claim 12 , wherein the quality control event comprises a purge process to purge the unacceptable thermosetting material.

15. A three-dimensional (3D) object production method comprising:

providing an extruded thermoset printing apparatus comprising:

an extrusion nozzle to deliver a thermosetting material to form a 3D object, and

a mixing chamber to receive and mix at least a first reactive component and a second reactive component to provide the thermosetting material;

detecting an obstruction within the extruded thermoset printing apparatus;

removing the obstruction within the extruded thermoset printing apparatus; and

producing the 3D object based on a 3D object design using thermosetting material delivered by the extruded thermoset printing apparatus,

wherein the removing comprises wiping the extrusion nozzle.

16. The method according to claim 15 , wherein detecting an obstruction within the extruded thermoset printing apparatus comprises analyzing one or more properties of the extruded thermoset printing apparatus to detect the obstruction.

17. The method according to claim 16 , wherein the extruded thermoset printing apparatus comprises one or more pumps to at least deliver each of the first reactive component and a second reactive component to the mixing chamber, wherein the one or more properties of the extruded thermoset printing apparatus comprises torque of the one or more pumps.

18. The method according to claim 15 , wherein the extruded thermoset printing apparatus comprises one or more flow meters to determine one or more of:
