1. A method for generating a three-dimensional object, comprising: (a) providing a powder bed in an enclosure, wherein the powder bed comprises a powder material having an elemental metal, metal alloy, ceramic, or an allotrope of elemental carbon;(b) directing an energy beam at the powder material along a path to transform at least a portion of the powder material to form a transformed material, which transformed material hardens into a hardened material as part of the three-dimensional object; and(c) using a heat sink adjacent to an exposed surface of the powder bed to remove thermal energy from the powder bed, wherein during removal of thermal energy from the powder bed, the heat sink is separated from the exposed surface by a gap, wherein the exposed surface of the powder bed is a top surface of the powder bed, and wherein a relative position of the heat sink with respect to the powder bed is adjustable while directing the energy beam at the powder material along the path. 2. The method of claim 1, wherein the gap is at a spacing between the heat sink and the top surface that is less than or equal to 50 millimeters. 3. The method of claim 1, wherein the transformed material is formed by fusing individual particles of the powder material. 4. The method of claim 3, wherein fusing comprises sintering, melting or binding the individual particles. 5. The method of claim 1, wherein the energy beam comprises an electromagnetic beam or a charged particle beam. 6. The method of claim 5, the energy beam comprises an electromagnetic beam that includes a laser beam. 7. The method of claim 1, further comprising disposing the heat sink within a path of the energy beam that extends from an energy source to the powder bed. 8. The method of claim 7, wherein the directing comprises directing the energy beam from the energy source to the powder bed through at least one opening disposed in the heat sink. 9. The method of claim 1, wherein the gap comprises a gas. 10. The method of claim 1, further comprising controlling a vacuum pressure in the enclosure. 11. The method of claim 10, further comprising controlling the vacuum pressure in the enclosure such that the vacuum pressure is at least 10′ Torr. 12. The method of claim 1, further comprising thermally coupling the heat sink to the powder bed through the gap. 13. The method of claim 1, further comprising adjusting the gap between the heat sink and the exposed surface. 14. The method of claim 13, wherein (c) comprises bringing the heat sink adjacent to the exposed surface of the powder bed to remove thermal energy from the powder bed, and regulating a spacing of the gap based on an energy level of the energy beam that is sufficient to transform the at least a portion of the powder material. 15. The method of claim 13, wherein (c) comprises bringing the heat sink adjacent to the exposed surface of the powder bed to remove thermal energy from the powder bed, and regulating at least one of (i) the gap and (ii) the energy source, to provide an energy level that is sufficient for generating the three-dimensional object at a deviation from a model of the three-dimensional object that is less than or equal to the sum of 25 micrometers and one thousandths of the fundamental length scale of the three-dimensional object. 16. The method of claim 1, wherein the heat sink facilitates removal of the thermal energy from the powder bed via conductive heat transfer. 17. The method of claim 1, further comprising cleaning the heat sink by using a cleaning member that removes the powder material or debris from a surface of the heat sink. 18. The method of claim 17, wherein cleaning the heat sink comprises rotating a brush. 19. The method of claim 17, wherein cleaning comprises using an opening port of the cleaning member. 20. The method of claim 1, further comprising reducing or preventing absorption of the powder material or debris on at least one surface of the heat sink using an anti-stick layer that forms a coating on the at least one surface of the heat sink. 21. The method of claim 1, further comprising collecting a remainder of the powder material or debris from the heat sink and/or the powder bed. 22. The method of claim 21, wherein the collecting comprises using negative pressure. 23. The method of claim 1, wherein upon formation of the hardened material, at least 30 percent of the heat removal occurs from the top surface of the powder bed using the heat sink. 24. The method of claim 1, wherein the heat sink is disposed above the exposed surface of the powder bed. 25. The method of claim 1, further comprising, after (b), cooling using a cooling member that cools by mechanical contact, wherein the cooling member is disposed outside of the enclosure. 26. The method of claim 25, wherein cooling using the cooling member comprises active cooling using a coolant. 27. The method of claim 25, wherein cooling using the cooling member comprises using a cooling liquid. 28. The method of claim 1, further comprising adjusting the relative position of the heat sink with respect to the powder while directing the energy beam at the powder material along the path. 29. The method of claim 1, wherein the relative position of the heat sink with respect to the powder bed is adjustable by tracking the path.
