An additive manufacturing system includes an ultrasonic inspection system integrated in such a way as to minimize time needed for an inspection process. The inspection system may have an ultrasonic phased array integrated into a build table for detecting defects in each successive slice of a workpiece and such that each slice may be re-melted if and when defects are detected.

A method for producing an additively manufactured, graded composite transition joint (AM-GCTJ) includes preparing a grating or lattice pattern from a first alloy A; the grating or lattice pattern includes pores in the grating or lattice patterns. The grating pattern is built from a first end to a second end being denser on the first end than on second end, and gradually reduces density by increasing the pore size and/or reducing density of the grating or lattice pattern; adding a second alloy B powder to the second end of grating or lattice pattern. The second alloy B powder is filled towards the first end. A composite is formed of first alloy A and second alloy B powder in the AM-GCTJ. The composite is subjected to hot isotropic pressing (HIP) to densify the composite. The second alloy B is graduated from the first end to the second end O of AM-GCTJ.

The extraction of a three-dimensional (3D) object is facilitated using a printed hint, which includes an additional shape that is printed along with the 3D object in a granular-based printer bed. In example implementations, the hint is indicative of a location of the 3D object. In one example, a hint has a dimension indicative of a depth to the object in the printer bed. In another example, a position of a hint is indicative that the object is below, and a size of the hint is based on a size of the object. Some hints can also protect the object. Examples include plate and shell-shaped hints. The object is located under a plate hint or within a shell hint. Further, an appearance of the object or indications of the sturdiness of different parts of the object can be printed on the hint to facilitate a safe extraction of the object.

A method for producing an impact-resistant component, in particular a component of a turbomachine, such as an aircraft engine, and a corresponding component. The component is produced at least partially by an additive manufacturing method from a powder material in such a way that the component is formed at least in a first region from a material with a first toughness and at least in a second region from a material with a second toughness, the second toughness being greater than the first toughness, and wherein the second region is formed, at least in a part of the component, as a continuous or interrupted layer, preferably parallel to the surface of the component, at a distance from the surface of the component.

A three-dimensional shaped object manufacturing method for shaping a three-dimensional shaped object. The three-dimensional shaped object manufacturing method includes a first step of shaping a first partial shaped object corresponding to a first partial path and a second partial shaped object corresponding to a second partial path in accordance with shaping data including path data and discharge amount data; a second step of measuring a first gap indicating a gap between the first partial shaped object and the second partial shaped object; and a third step of executing an adjustment processing of adjusting, based on a difference between the first gap and a second gap determined based on the shaping data and corresponding to the first gap, a discharge amount in a third partial path which is one of the plurality of paths and along which the discharge unit moves after the first partial path and the second partial path.

Systems and methods for the manufacture of a solid wire using additive manufacturing techniques are disclosed. In one embodiment, a fine powdery material is sintered or melted or soldered or metallurgically bonded onto a metal strip substrate in a compacted solid form or a near-net shape (e.g., a near-net solid wire shape) before being turned into a final product through forming or drawing dies.
