METHOD FOR MANUFACTURING PARTS OR DEVICES AND FORMING TRANSITION LAYERS FACILITATING REMOVAL OF PARTS AND DEVICES FROM BUILD-PLATES

A method for manufacturing parts or devices using additive manufacturing is provided. The method forms the parts or devices, and also forms a transition layer or transition layers of partially or incompletely sintered powder between a build-plate and/or supports provided on the build-plate, and/or a gap or gaps of unsintered powder, or partially or incompletely sintered powder between the supports and the parts. The transition layer(s) and the gap(s) facilitate separation of the parts or devices from the build-plate or the supports provided on the build-plate.

ADDITIVELY MANUFACTURED SELF-DESTRUCTIVE DELAY DEVICE

The system and method for an additively manufactured self-destructive delay device is a bellow/lattice structure or other form. The device may be installed as a replacement to a previous device, where the device yields under the deployment force at a specific rate to match the time-displacement curve established by a previous hydraulic delay device. The delay device has a virtually unlimited lifespan, is cheap to manufacture, and can be adaptable to other loads and conditions for use in or on other platforms. This solution can be applied anywhere where mechanical delay devices are needed within systems. Some examples include wing/fin deployment mechanisms, safety crumple zones, or devices that act as shear pins.

Set of cutting inserts and methods of making a set of cutting inserts

A set of cutting inserts includes a stem portion, a plurality of branch portions attached to and extending from the stem portion, and at least one cutting insert attached to each of the plurality of branch portions. The stem portion has a longitudinal axis extending between a top end of the stem portion and a bottom end of the stem portion and at least one of the top end of the stem portion is disposed along the longitudinal axis above uppermost portions of each cutting insert, and the bottom end of the stem portion is disposed along the longitudinal axis below lowermost portions of each cutting insert. Also, methods for manufacturing a set of cutting inserts are disclosed.

REINFORCEMENT OF A DEPOSITED STRUCTURE FORMING A METAL MATRIX COMPOSITE

A method for forming a reinforced metallic structure includes providing a tool having a formation surface corresponding to a desired structure shape of the reinforced metallic structure. The method also includes positioning a plurality of fibers on the formation surface of the tool. The method also includes depositing a layer of material on the plurality of fibers using a cold-spray technique. The method also includes removing the layer of material with the plurality of fibers from the tool to create the reinforced metallic structure.

CREATING A BREAKAWAY REGION

An apparatus is disclosed to create a breakaway junction for 3D printed parts. Powder is spread along a target zone, such as a build bed. A liquid functional agent is selectively dispensed upon the powder to form a 3D object, a supporting part, and the breakaway junction between them.

ADDITIVE MANUFACTURED COMPONENTS INCLUDING INTEGRALLY FORMED PASSAGES, CHANNELS, AND CONDUITS, AND METHODS OF FORMING SAME

Additively manufactured components including unitary bodies. The component may include a unitary body having a component section. The component section may include at least one passage extending at least partially through the component section. The unitary body may also include a supplemental section formed integral with the component section. The supplemental section may be disposed over the passage(s) of the component section and may include a channel extending at least partially through the supplemental section. The channel may be in fluid communication with the passage(s) of the component section. Additionally, the unitary body may include a transition conduit positioned within the component section and the supplemental section. The transition conduit may extend between the passage(s) of the component section and the channel of the supplemental section to fluidly couple the passage(s) and the channel.
