Methods and systems for 3D printing with modifiable support

1. A method, by a processor, for 3D printing an object, comprising:

selecting an object to be printed by a 3D printer comprised of a frame having a lower portion and an upper portion, and a structure having a plurality of movable sections disposed within the lower portion, wherein the upper portion is of an open-frame configuration having a plurality of vertical and horizontal supporting members and extends upward from the lower portion, wherein the lower portion is of a closed-frame configuration and encloses a base of the frame containing an actuation system, wherein, when in an initial position, each of the plurality of movable sections are positioned at a first, same height commensurate with a reference line above the base of the frame such that a top surface of each of the plurality of movable sections are flush with one another and together form a level surface of the structure at the reference line in a mid-section of the upper portion;

in response to selecting the object and prior to commencing printing of the selected 3D object, causing the structure to be modified from a first, planar shape of the initial position to a second, featured shape based on a shape of the selected object to be printed, wherein the causing of the structure to be modified includes causing at least some of the plurality of movable sections to move relative to the others of the plurality of movable sections, wherein, when in the initial position, each of the plurality of movable sections is centered halfway between a highest and lowest possible position each respective section of the plurality of movable sections is able to move, and wherein the moving of the at least some of movable sections relative to one another includes causing a first number of the plurality of movable sections to be raised to a second height above the reference line above the base of the frame and a second number of the plurality of movable sections to be lowered from the initial position to a depth below the reference line beneath the base of the frame when the structure is in the second, featured shape;

in response to selecting the object and causing the structure to be modified from the first, planar shape to the second, featured shape, commencing printing of the 3D object, wherein the modified structure is fixed in the second, featured shape from the commencement of the printing of the 3D object until a completion of the printing of the 3D object; and

printing the selected object by the 3D printer utilizing at least one of a plastic and a polymer, wherein at least a portion of the selected object is supported by the modified structure of the second, featured shape while the selected object is being 3D printed by the 3D printer.

2. The method of claim 1 , wherein the plurality of movable sections are each configured to move in a direction that is substantially parallel to that of the others of the plurality of movable sections.

3. The method of claim 2 , wherein the plurality of movable sections are substantially identical.

4. The method of claim 1 , wherein the 3D printer further includes a 3D printer head positioned above the structure.

5. A computer program product for 3D printing an object by a processor, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

an executable portion that selects an object to be printed by a 3D printer comprised of a frame having a lower portion and an upper portion, and a structure having a plurality of movable sections disposed within the lower portion, wherein the upper portion is of an open-frame configuration having a plurality of vertical and horizontal supporting members and extends upward from the lower portion, wherein the lower portion is of a closed-frame configuration and encloses a base of the frame containing an actuation system, wherein, when in an initial position, each of the plurality of movable sections are positioned at a first, same height commensurate with a reference line above the base of the frame such that a top surface of each of the plurality of movable sections are flush with one another and together form a level surface of the structure at the reference line in a mid-section of the upper portion;

an executable portion that, in response to selecting the object and prior to commencing printing of the selected 3D object, causes the structure to be modified from a first, planar shape of the initial position to a second, featured shape based on a shape of the selected object to be printed, wherein the causing of the structure to be modified includes causing at least some of the plurality of movable sections to move relative to the others of the plurality of movable sections, wherein, when in the initial position, each of the plurality of movable sections is centered halfway between a highest and lowest possible position each respective section of the plurality of movable sections is able to move, and wherein the moving of the at least some of movable sections relative to one another includes causing a first number of the plurality of movable sections to be raised to a second height above the reference line above the base of the frame and a second number of the plurality of movable sections to be lowered from the initial position to a depth below the reference line beneath the base of the frame when the structure is in the second, featured shape;

an executable portion that, in response to selecting the object and causing the structure to be modified from the first, planar shape to the second, featured shape, commences printing of the 3D object, wherein the modified structure is fixed in the second, featured shape from the commencement of the printing of the 3D object until a completion of the printing of the 3D object; and

an executable portion that prints the selected object by the 3D printer utilizing at least one of a plastic and a polymer, wherein at least a portion of the selected object is supported by the modified structure of the second, featured shape while the selected object is being 3D printed by the 3D printer.

6. The computer program product of claim 5 , wherein the plurality of movable sections are each configured to move in a direction that is substantially parallel to that of the others of the plurality of movable sections.

7. The computer program product of claim 6 , wherein the plurality of movable sections are substantially identical.

8. The computer program product of claim 5 , wherein the 3D printer further includes a 3D printer head positioned above the structure.
