Abstract: Techniques for pre-heating the powders of layer deposited on the powder bed during a 3-D print process conducted by a 3-D printer are disclosed. A re-coater includes a heat source that pre-heats the deposited layer as a leveling member of the re-coater smooths the layer onto the powder bed. In some embodiments, the re-coater reheats the powder bed following the selective fusing of a layer by an energy beam source. The consistent pre-heating and re-heating of the powder directly on the surface of the powder bed maximally reduces damage, cracks, dimensional flaws, and other artifacts created by excessive thermal gradients in the case where heat is not used.

Abstract: 3-D build jobs having surrogate supports, 3-D printers using surrogate supports, and techniques to support vulnerable regions of build pieces using surrogate supports are disclosed. The surrogate supports are generated in a first material configuration and are offset via a gap from the vulnerable regions. The gap comprises a second material configuration, such as loose or partially fused powder on which the build piece can be supported during 3-D printing. In alternative embodiments, the gap instead includes thin manual ties or a solid body using material that is stronger but more amenable to breaking off without damaging the build piece. Post-processing steps are dramatically reduced as the surrogate supports and gaps facilitate virtually error-free separation from the build piece. In an embodiment, the surrogate supports include a support structure extending to a fixed base underneath, the fixed base being a build plate or a global surrogate.

Abstract: Systems and methods for rotational additive manufacturing are disclosed. An apparatus in accordance with an aspect of the present disclosure comprises a build floor, a depositor system configured to deposit a layer of powder onto the build floor, a motor system causing a rotational motion between the depositor system and the build floor, wherein the depositor system deposits the layer of powder during the rotational motion, a receptacle wall configured to contain the powder on the build floor, an energy beam source configured to apply an energy beam in an active area of the layer of powder to selectively fuse a portion of the powder in the active area to form a portion of a build piece and a gas flow system configured to provide a gas flow across the active area while the energy beam selectively fuses the portion of the layer of powder in the active area.
