Abstract

Embodiments include an apparatus for fabricating a three-dimensional object from a digital representation of the object stored in a computer readable media, the apparatus comprising: a component having a surface on which the object is to be fabricated, wherein information is embedded within the component; a sensor configured to sense the information embedded within the component; a module configured to, based on the sensor sensing the information embedded within the component, determine one or both of (i) a characteristic of the component and (ii) a configuration parameter of the apparatus; and a print mechanism disposed above the surface of the component, wherein the print mechanism is configured to, based on the determined one or both of (i) the characteristic of the component and (ii) the configuration parameter of the apparatus, fabricate the object on the surface of the component.

First claim

What is claimed is:

1. An apparatus for fabricating a three-dimensional object from a digital representation of the object stored in a computer readable media, the apparatus comprising:
a component having a surface on which the object is to be fabricated, wherein information is embedded within the component;
a sensor configured to sense the information embedded within the component;
a module configured to, based on the sensor sensing the information embedded within the component, determine one or both of (i) a characteristic of the component and (ii) a configuration parameter of the apparatus; and
a print mechanism disposed above the surface of the component, wherein the print mechanism is configured to, based on the determined one or both of (i) the characteristic of the component and (ii) the configuration parameter of the apparatus, fabricate the object on the surface of the component,
wherein the component is a table insert that is removably attached to a table frame of the apparatus.

2. The apparatus of claim 1 , wherein the sensor is attached to the table frame.

3. The apparatus of claim 1 , wherein the module is configured to determine one or both of (i) the characteristic of the component and (ii) the configuration parameter of the apparatus by:
accessing a server over a network; and
based on the information sensed by the sensor, retrieving, from the server, one or both of (i) the characteristic of the component and (ii) the configuration parameter of the apparatus.

4. The apparatus of claim 1 , wherein the characteristic of the component comprises information associated with one of a thickness of the component, a surface finish of the component, a surface evenness of the component, and a thermal property of the component.

5. The apparatus of claim 1 , wherein the configuration parameter of the apparatus comprises one of a speed with which the print mechanism fabricates the object, a type and specification of glue to be disposed on the surface of the component while the object is being fabricated, a heating pattern for heating the component while the object is being fabricated, a cooling pattern for cooling the component while the object is being fabricated, a pressure with which printing material is to be deposited by the print mechanism while the object is being fabricated, and a setting of an extruder used for fabricating the object.

6. The apparatus of claim 1 , wherein:
the information is embedded within the component in a form of a bar code disposed on the surface of the component; and
the sensor is configured to scan the bar code to sense the information represented by the bar code.

7. The apparatus of claim 1 , further comprising:
a near-field communication (NFC) tag embedded within or attached to the component,
wherein the NFC tag stores the information, and
wherein the sensor comprises a NFC tag reader configured to read the information stored in the NFC tag.

8. The apparatus of claim 1 , further comprising:
a radio frequency identifier (RFID) tag embedded within or attached to the component,
wherein the RFID tag stores the information, and
wherein the sensor comprises a RFID reader configured to read the information stored in the RFID tag.

9. The apparatus of claim 1 , further comprising:
a memory embedded within or attached to the component,
wherein the memory stores the information, and
wherein the sensor comprises a memory port and a circuit to read information stored in the memory.

10. A method for fabricating a three-dimensional object from a digital representation of the object stored in a computer readable media, the method comprising:
sensing, by a sensor, information embedded within a component, wherein the component has a surface, and wherein the component is a table insert;
based on sensing the information embedded within the component, determining, by a module, one or both of (i) a characteristic of the component and (ii) a configuration parameter associated with fabricating the object;
based on determining one or both of (i) the characteristic of the component and (ii) the configuration parameter associated with fabricating the object, fabricating, by a print mechanism, the object on the surface of the component, and
removably attaching the table insert to a table frame.

11. The method of claim 10 , wherein determining one or both of (i) the characteristic of the component and (ii) the configuration parameter associated with fabricating the object comprises:
accessing a server over a network; and
based on the information sensed by the sensor, retrieving, from the server, one or both of (i) the characteristic of the component and (ii) the configuration parameter of the apparatus.

12. The method of claim 10 , wherein the characteristic of the component comprises information associated with one of a thickness of the component, a surface finish of the component, a surface evenness of the component, and a thermal property of the component.

13. The method of claim 10 , wherein the configuration parameter associated with fabricating the object comprises one of a speed with which the print mechanism fabricates the object, a type and specification of glue to be disposed on the surface of the component while the object is being fabricated, a heating pattern for heating the component while the object is being fabricated, a cooling pattern for cooling the component while the object is being fabricated, a pressure with which printing material is to be deposited by the print mechanism while the object is being fabricated, and a setting of an extruder used for fabricating the object.

14. The method of claim 10 , wherein the information is embedded within the component in a form of a bar code disposed on the surface of the component, wherein the sensor comprises a bar code reader, and wherein sensing the information embedded within the component comprises:
scanning the bar code to sense the information represented by the bar code.

15. The method of claim 10 , wherein a near-field communication (NFC) tag, which is embedded within or attached to the component, stores the information, wherein the sensor comprises a NFC tag reader, and wherein sensing the information embedded within the component comprises:
reading, using the NFC reader, the information stored in the NFC tag.

16. The method of claim 10 , wherein a radio frequency identifier (RFID) tag, which is embedded within or attached to the component, stores the information, wherein the sensor comprises a RFID tag reader, and wherein sensing the information embedded within the component comprises:
reading, using the RFID tag reader, the information stored in the RFID tag.

17. The method of claim 10 , wherein a memory, which is embedded within or attached to the component, stores the information, wherein the sensor comprises a memory port and a circuit, and wherein sensing the information embedded within the component comprises:
reading, by the memory port and the circuit, the information stored in the memory.
