Abstract

Three-dimensional printing of objects is facilitated. For an object to be printed in three-dimensions (3D), one or more contact points relating to the object are determined. A contact point is at least one location on a base of a 3D printer in which a portion of the object is to contact the base based on printing the portion of the object. A centralized location of the base at which one or more movable blocks of the base are to be moved to position the one or more contact points at the centralized location to facilitate printing of the one or more portions of the object is also determined. A print plan to be used to print the object in three-dimensions is created, in which the print plan includes one or more instructions to print at least the one or more portions of the object at the centralized location.

First claim

What is claimed is:

1. A system for facilitating three-dimensional printing of objects, the system comprising:
at least one processing circuit, wherein the at least one processing circuit is configured to perform a method, said method comprising:
determining for an object to be printed in three-dimensions (3D) one or more contact points relating to the object, wherein a contact point is at least one location on a base of a 3D printer in which a portion of the object is to contact the base based on printing the portion of the object;
determining a centralized location of the base in x and y directions at which one or more movable blocks of the base are to be moved to position the one or more contact points at the centralized location to facilitate printing one or more portions of the object at the centralized location, the centralized location being a region of the base in which the one of more portions of the object are printed in close proximity in the x and y directions; and

creating at least one print plan to be used to print the object in three-dimensions, the at least one print plan comprising one or more instructions to print at least the one or more portions of the object at the centralized location and one or more addition instructions to reposition in at least one direction of the x and y directions at least one movable block of the one or more movable blocks to a different position away from the centralized location to continue printing the object.

2. The system of claim 1 , wherein the method further comprises:
initiating an action based on creating, at least, a print plan of the at least one print plan, the initiating the action comprising, at least, providing the print plan to be used in printing the at least one or more portions of the object at the centralized location.

3. The system of claim 1 , wherein the one or more additional instructions comprise at least one instruction to print one or more remaining portions of the object, the one or more remaining portions of the object including a core of the object.

4. The system of claim 1 , wherein the method further comprises determining a number of movable blocks to be used to position the one or more contact points.

5. The system of claim 4 , wherein the determining the number of movable blocks comprises:
identifying a dimension of a movable block;
determining at least one dimension of at least one portion of the object; and
selecting the number of movable blocks based on the dimension of the movable block and the at least one dimension of the at least one portion of the object.

6. The system of claim 1 , wherein the method further comprises:
determining, based on performing, via, at least, a print plan of the at least one print plan, 3D printing of at least a part of the object, one or more metrics of a current status of the 3D printing of the object;
determining, based on the metrics, whether additional movement of at least one movable block of the base is to be performed; and
providing, based on determining that additional movement is to be performed, an indication of the additional movement of the at least one movable block to facilitate the performing the 3D printing.

7. The system of claim 1 , wherein the method further comprises providing an indication to lock the one or more movable blocks in position subsequent to moving the one or more movable blocks to prevent the one or more movable blocks from further movement.

8. The system of claim 1 , wherein the one or more additional instructions comprise at least one instruction to reposition, one or more times, at least one movable block of the one or more movable blocks to one or more different positions to continue printing the object.

9. The system of claim 1 , wherein the method further comprises:
creating a plurality of print plans based on, at least, coordinates of the object, the one or more contact points and one or more centralized locations; and
selecting, at least, a print plan of the at least one print plan from the plurality of print plans based on an optimization criterion.

10. The system of claim 9 , wherein the optimization criterion comprises fewer movements of a printer head of the 3D printer, wherein the print plan selected uses fewer movements of the printer head than other print plans of the plurality of print plans.

11. A computer program product for facilitating three-dimensional printing of objects, the computer program product comprising:
one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media to perform a method comprising:
determining for an object to be printed in three-dimensions (3D) one or more contact points relating to the object, wherein a contact point is at least one location on a base of a 3D printer in which a portion of the object is to contact the base based on printing the portion of the object;
determining a centralized location of the base in x and y directions at which one or more movable blocks of the base are to be moved to position the one or more contact points at the centralized location to facilitate printing one or more portions of the object at the centralized location, the centralized location being a region of the base in which the one or more portions of the object are printed in close proximity in the x and y directions; and
creating at least one print plan to be used to print the object in three-dimensions, the at least one print plan comprising one or more instructions to print at least the one or more portions of the object at the centralized location and one or more additional instructions to reposition in at least one direction of the x and y directions at least one movable block of the one or more movable blocks to a different position away from the centralized location to continue printing the object.

12. The computer program product of claim 11 , wherein the one or more additional instructions comprise at least one instruction to print one or more remaining portions of the object, the one or more remaining portions of the object including a core of the object.

13. The computer program product of claim 11 , wherein the method further comprises:
determining, based on performing, via, at least, a print plan of the at least one print plan, 3D printing of at least a part of the object, one or more metrics of a current status of the 3D printing of the object;
determining, based on the metrics, whether additional movement of at least one movable block of the base is to be performed; and
providing, based on determining that additional movement is to be performed, an indication of the additional movement of the at least one movable block to facilitate the performing the 3D printing.

14. The computer program product of claim 11 , wherein the one or more additional instructions comprise at least one instruction to reposition, one or more times, at least one movable block of the one or more movable blocks to one or more different positions to continue printing the object.

15. The computer program product of claim 11 , wherein the method further comprises:
creating a plurality of print plans based on, at least, coordinates of the object, the one or more contact points and one or more centralized locations; and
selecting, at least, a print plan of the at least one print plan from the plurality of print plans based on an optimization criterion.

16. A computer-implemented method of facilitating three-dimensional printing of objects, the computer-implemented method comprising:
determining for an object to be printed in three-dim
