1. A method for printing a three-dimensional object, comprising:
- (I) providing at least one controller configured to;
(a) direct an energy source to generate an energy beam that irradiates an exposed surface of a material bed comprising a pre-transformed material at a first position using an energy beam during a first time period of at least one tenth of a millisecond, to transform the pre-transformed material at the first position to a transformed material to form a first tile as part of the three-dimensional object, which first position is along a path-of-tiles, wherein during the first time period, the energy beam is stationary or substantially stationary;
(b) direct a guidance system to translate the energy beam to a second position of the exposed surface along the path-of-tiles, which second position is different from the first position, wherein the energy beam is translated during an intermission without transforming the pre-transformed material along the path-of-tiles;
(c) direct the guidance system to direct the energy beam to irradiate the exposed surface of the material bed at the second position with the energy beam at the second position during a second time period of at least one tenth of a millisecond, to transform the pre-transformed material at the second position to the transformed material to form a second tile as part of the three-dimensional object, wherein during the second time period, the energy beam is stationary or substantially stationary; and
(II) using the at least one controller to form the first tile and the second tile as part of the three-dimensional object.

16. An apparatus for printing a three-dimensional object, comprising at least one controller that is operatively coupled to an energy source and a guidance system, which at least one controller is configured to:
-
(a) direct the energy source to generate an energy beam that irradiates an exposed surface of a material bed at a first position using an energy beam during a first time period of at least one tenth (0.1) of a millisecond, to transform a pre-transformed material in the material bed at the first position to a transformed material to form a first tile as part of the three-dimensional object, which first position is along a path-of-tiles, wherein during the first time period, the energy beam is stationary or substantially stationary; (b) direct the guidance system to translate the energy beam to a second position of the exposed surface along the path-of-tiles, which second position is different from the first position, wherein the energy beam is translated during an intermission without transforming the pre-transformed material along the path-of-tiles; and (c) direct the guidance system to direct irradiation of the energy beam at the exposed surface of the material bed at the second position with the energy beam at the second position during a second time period of at least one tenth (0.1) of a millisecond, to transform the pre-transformed material at the second position to the transformed material to form a second tile as part of the three-dimensional object, wherein during the second time period, the energy beam is stationary or substantially stationary. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
