This disclosure, and the exemplary embodiments provided herein, include AM processed Ti-MMCs reinforced with either aluminum oxide or tantalum pentoxide. According to an exemplary embodiment, composite feedstock powders of Ti-6Al-4V (Ti64) with 1% and 3% (by volume) reinforcements of either nano-Al.sub.2O.sub.3 or Ta.sub.2O.sub.5 are prepared by high energy ball milling and then 3-D printed using SLM.

A data generation program includes instructions of: acquiring three-dimensional data representing a three-dimensional shape of a three-dimensional product; acquiring an arrangement condition for arranging a support member to the three-dimensional product; setting an extending direction, a width direction, and a height direction of the support member; adding a cutting margin of a particular thickness to a cutting surface of the three-dimensional product at one side in the height direction; setting the support member in accordance with the arrangement condition, one end of the support member in the extending direction being connected to the cutting margin added to the three-dimensional product; setting a beam, the beam being spaced from the three-dimensional product having the cutting margin in the extending direction, the beam extending in the width direction; generating three-dimensional modeling data for modeling a modeled object by using a three-dimensional modeling apparatus; and outputting the three-dimensional modeling data.

Provided is a gas turbine vane and blade assembly in which lattice structures are installed between an impingement plate and an effusion plate. The gas turbine vane and blade assembly is capable of enhancing cooling efficiency in an impingement/effusion cooling technique.

In addition, the gas turbine vane and blade assembly can be manufactured using an additive manufacturing technique, and the lattice structures are capable of replacing supports that are used during an additive manufacturing process, and improving not only structural rigidity and stability but also cooling performance.

A removal apparatus for aiding in the removal of an additive manufacturing build plate from a support structure is provided. The removal apparatus may include a plurality of printed geometries disposed proximate one or more fasteners securing or anchoring the build plate to the support structure. The printed geometries may be printed concurrently with the additive manufacturing article. The apparatus may further include one or more expansion bolts sized for installation between a pair of printed geometries positioned apart from one another. The expansion bolts may include a small lead screw, a large lead screw and a coupling nut. In operation, rotation of the coupling nut in a first direction lengthens the expansion bolt to push the printed geometry outward thereby reducing the distortion in the build plate so that the fastener between the build plate and the support structure may be removed.

A 3D-printed aluminum fuel fitting solution demonstrates higher performance at a potentially lower cost and shorter lead time. The resulting geometry also produced 30% weight savings leaving all interfaces intact.

A manipulator device such as a robot arm that is capable of increasing manufacturing throughput for additively manufactured parts, and allows for the manipulation of parts that would be difficult or impossible for a human to move is described. The manipulator can grasp various permanent or temporary additively manufactured manipulation points on a part to enable repositioning or maneuvering of the part.

An additively manufactured in-process structure includes, a base, a first cantilever element extending from the base, and a first heat sink adjacent to the first cantilever element and configured for absorbing heat from the first cantilever element during an additive manufacturing process. A gap is formed between the first cantilever element and the first heat sink and the first heat sink is spaced from any rigid substrate underlying and supporting the first heat sink.
