Abstract: A method of removing supporting structures from an object produced by an additive manufacturing process is presented, in which a supporting structure is provided between a target structure and a base plate and has a connection thereto, and one of the connections is released by excitation using mechanical vibrations. To enable a more efficient and safer removal of the supporting structures without damaging the elements of the object themselves, by way of the use of an actuator coupled to the target structure or an intermediate element, one mechanical excitation vibration is introduced and is excited with a resonance vibration in order to release the one connection in that the deflection of the resonance vibration exceeds the load limit of the supporting structure.

Abstract: A blade for a gas turbine includes a removed portion space, and further includes an airfoil portion defining the removed portion space, the airfoil portion formed from a base material, and a replacement component formed to fill the removed portion space. The replacement component is formed from a material that includes 50%-80% base material, 0%-30% braze material, and 0%-8% aluminum. A braze joint is formed between the airfoil portion and the replacement component to attach the replacement component to the airfoil portion and fill the removed portion space.

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: A system and method are described for post-processing a 3D printed component. For example, support structures for the 3D printed component may be removed during post-processing. In the system and method, a first image of a component is stored in memory. A second image of a 3D printed component corresponding to the component is also captured. One or more cutting paths between the 3D printed component and the support structures is then determined based on the first image and the second image. The 3D printed component may then be autonomously separated from the support structures by cutting through the cutting path.

Abstract: A method for manufacturing a three-dimensional shaped object includes: a step of stacking a layer containing a first inorganic powder and a first binder to form a first component, the first component being bonded to a second component containing a second inorganic powder and a second binder by a heat treatment; and a support body forming step of forming, by stacking the layer, a support body which is removed after the heat treatment. The heat treatment is executed on an aggregate. The support body is formed in the aggregate to support an overhang portion from below between the first component and the second component. The support body forming step includes: a step of forming a support main body portion by stacking the layer containing the first inorganic powder and the first binder; a step of forming a first contact portion in contact with the first component in the aggregate by stacking a layer containing a third inorganic powder having a melting point higher than that of the first inorganic powder and the second inorganic powder; and a step of forming a second contact portion in contact with the second component in the aggregate.
