Abstract

A method, apparatus, and system are provided for the printing and maturation of living tissue in an Earth-referenced reduced gravity environment such as that found on a spacecraft or on other celestial bodies. The printing may be three-dimensional structures. The printed structures may be manufactured from low viscosity biomaterials.

Claims (33)

1. An additive manufacturing apparatus comprising:

a reduced gravity environment;

one or more cell culturing devices in said reduced gravity environment, wherein said one or more cell culturing devices includes an interior;

a bioprinter positioned in said reduced gravity environment, wherein said bioprinter has one or more print heads;

one or more bioinks in fluid communication with said one or more print heads;

said one or more bioinks in fluid communication with the interior of said one or more cell culturing devices to print one or more tissues and wherein said one or more cell culturing devices incubates said one or more tissues.

2. The apparatus of claim 1 wherein said cell culturing device is removable from said bioprinter.

3. The apparatus of claim 2 wherein said cell culturing device includes an integrated life support system for transportation of said cell culturing device from said reduced gravity environment to an environment having a different gravity.

4. The apparatus of claim 1 wherein said one or more tissues is one or more three-dimensional tissues.

5. The apparatus of claim 1 wherein said cell culturing device includes at least one of a mechanical tissue stimulation or electrical tissue stimulation.

6. The apparatus of claim 1 wherein said reduced gravity environment is both temperature and humidity controlled.

7. The apparatus of claim 1 wherein said bioprinter includes thermal control.

8. The apparatus of claim 7 wherein said one or more print heads include thermal control.

9. The apparatus of claim 8 wherein said one or more print heads include one or more dispenser tips, wherein the one or more dispenser tips include thermal control.

10. The apparatus of claim 1 wherein said one or more bioinks are thermally controlled.

11. The apparatus of claim 1 wherein said one or more print heads are removable and replaceable.

12. The apparatus of claim 1 wherein at least one of said one or more print heads allow direct write constant pressure extrusion.

13. The apparatus of claim 1 wherein at least one liquid media immerses said one or more printed tissues in said cell culturing device, wherein said at least one liquid media is thermally controlled.

14. A biomanufacturing system capable of assembling and maturing living tissue in a reduced gravity environment from one or more bioinks comprising:

a reduced gravity environment;

a bioprinter, wherein said bioprinter is a three dimensional printer having one or more print heads, wherein one or more components of said bioprinter are thermally controlled;

a cell culturing device having an unoccupied interior, wherein said one or more print heads is in fluid communication with said unoccupied interior within said reduced gravity environment;

one or more bioinks; and

said reduced gravity environment surrounding said bioprinter and said cell culturing device;

wherein said one or more print heads print one or more three-dimensional tissues with said one or more bioinks into said unoccupied interior of said cell culturing device.

15. The biomanufacturing system of claim 14 wherein said cell culturing device incubates said one or more three-dimensional tissues, and at least one of a mechanical tissue stimulation or electrical tissue stimulation.

16. The biomanufacturing system of claim 15 wherein said cell culturing device includes both said mechanical tissue stimulation and said electrical tissue stimulation.

17. The biomanufacturing system of claim 14 wherein at least one of said one or more print heads includes a first dispenser tip and a second dispenser tip, wherein said first dispenser tip is different from said second dispenser tip.

18. The biomanufacturing system of claim 14 wherein said reduced gravity environment is at least one of temperature or humidity controlled.

19. The biomanufacturing system of claim 18 wherein said reduced gravity environment is both temperature and humidity controlled.

20. The biomanufacturing system of claim 14 wherein at least one of said one or more print heads is removable and replaceable with a different print head.

21. The biomanufacturing system of claim 14 further comprising one or more print stages, wherein at least one of said one or more print stages or said one or more print heads are thermally controlled.

22. The biomanufacturing system of claim 21 wherein said one or more print heads is thermally controlled.
