1. A method for generating a three-dimensional object, comprising: (a) dispensing a first layer of powder material in an enclosure to provide a powder bed having a first top surface;(b) directing an energy beam to the first layer of powder material to generate at least a portion of the three-dimensi
1. A method for generating a three-dimensional object, comprising: (a) dispensing a first layer of powder material in an enclosure to provide a powder bed having a first top surface;(b) directing an energy beam to the first layer of powder material to generate at least a portion of the three-dimensional object from at least a portion of the first layer;(c) dispensing a second layer of powder material in the enclosure, wherein the second layer of powder material comprises a second top surface;(d) shearing the second layer of powder material to form a first planar surface, wherein the shearing comprises using a blade or an air knife, wherein the first planar surface is at or below a lowest point of the second top surface; and(e) removing substantially all powder material that is above a second planar surface from the second layer of powder material, wherein the removing comprises using vacuum suction, magnetic force, electrostatic force, or gas flow, wherein the second planar surface is located below the first planar surface, wherein the removing occurs in the absence of contacting the powder bed, and wherein during the removing, the first layer of powder material comprises flowable powder material. 2. The method of claim 1, wherein the powder material comprises an elemental metal, metal alloy, ceramic, or an allotrope of elemental carbon. 3. The method of claim 1, wherein the generating comprises transforming the powder material to generate a transformed material that subsequently hardens into a hardened material, wherein at least a portion of the hardened material protrudes from the first top surface, thus forming a protrusion. 4. The method of claim 3, wherein the protrusion is at least a portion of the three-dimensional object. 5. The method of claim 3, wherein the protrusion comprises warping, bending, bulging, or balling of the hardened material. 6. The method of claim 3, wherein the protrusion comprises a hardened material that is not part of the three-dimensional object. 7. The method of claim 3, wherein the protrusion has a height from about 10 micrometers to about 500 micrometers with respect to the first top surface. 8. The method of claim 3, wherein the protrusion protrudes from the second planar surface. 9. The method of claim 3, wherein the protrusion does not protrude from either the first planar surface or second top surface. 10. The method of claim 1, wherein an average vertical distance from the first top surface to the second planar surface is from about 5 micrometers to about 1000 micrometers. 11. The method of claim 10, wherein an average vertical distance from the first top surface to the first planar surface is from about 10 micrometers to about 500 micrometers. 12. The method of claim 1, wherein the removing comprises using the vacuum suction. 13. The method of claim 1, further comprising reusing an excess of powder material from the first layer and/or second layer. 14. The method of claim 1, wherein the second planar surface is situated above the first top surface. 15. The method of claim 1, wherein upon shearing the second layer of powder material to form the first planar surface, the at least the portion of the three-dimensional object is displaced by about 300 micrometers or less. 16. The method of claim 1, wherein the dispensing comprises dispensing the powder material from a powder dispenser that is separated from the second top surface by a gap. 17. The method of claim 16, wherein the gap has a separation distance that is from about 10 micrometers to about 50 millimeters. 18. The method of claim 1, wherein the removing is synchronized with the dispensing of the second layer to form a uniformly planar second planar surface. 19. The method of claim 1, wherein the dispensing comprises using a powder dispenser comprising an exit opening port, and wherein at least one obstruction is situated at the exit opening port or between the exit opening port and a top surface of the powder bed. 20. The method of claim 19, wherein the obstruction comprises a rough surface. 21. The method of claim 19, wherein the obstruction comprises a mesh or a plane with holes. 22. The method of claim 1, wherein the removing comprises using a powder removing member comprising a powder entry port. 23. The method of claim 22, wherein the powder removing member comprises a vacuum nozzle. 24. The method of claim 1, wherein the powder bed comprises individual particles formed of the powder material, and wherein the powder material is selected from the group consisting of an elemental metal, metal alloy, ceramic, or allotrope of elemental carbon. 25. The method of claim 1, wherein the gas flow is laminar. 26. The method of claim 1, wherein dispensing comprises using a powder dispenser that is coupled to at least one height sensor. 27. The method of claim 1, wherein dispensing comprises using a powder dispenser that provides the powder material, which power dispenser is subjected to vibration. 28. The method of claim 1, wherein the second layer of powder material covers at least a portion of the first layer of powder material. 29. The method of claim 1, wherein the shearing comprises using the blade. 30. The method of claim 1, wherein the shearing comprises using the air knife.
