Abstract: A structural component, or parts thereof, for a machine system or vehicle, such as an aircraft, is provided. In some examples, the structural component includes at least one embedded passageway or line. In other examples, the passageway or line is formed integrally on the exterior surface of the structural component. In some of these examples, the structural component can benefit from additive manufacturing techniques or methodologies.

Abstract: Examples that relate to snubbing devices to arrest or resist motion are provided. These snubbing devices are suitable for use with actuators, such as linear actuators, that desire load damping or piston speed change at the end of stroke movement of the actuator. Embodiments of the present disclosure also relate to linear actuators having a snubbing device for dampening loads, reducing piston velocity, etc., at the end of stroke movement of the actuator. In some embodiments, the snubbing device and/or other components of the actuator can benefit from additive manufacturing techniques or methodologies.

Abstract: Generally described, a hybrid additive manufacturing method may be used to produce complex parts using additive manufacturing technologies. The methods may include manufacturing one or more first portions of the part with a first additive manufacturing process, such as a powder bed fusion process using a metallic powder source material. The first portion of the part is then transferred to an operating bed of a second additive manufacturing process, such as a direct deposition process using a solid metallic source material. In this regard, the first additive manufacturing process is different from the second additive manufacturing process. Next, another portion of the part is manufactured, coupled to, and partially surrounding the first portion of the part using the second additive manufacturing process, portions of which may be machined with a tool to provide a finished part.

Abstract: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. A large variety of patterns may be formed in SMP-integrated fabrics based upon how the shape memory polymer is integrated into the base fabric. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality. By using multiple formulations of SMP on a single piece of fabric, a large combination of material properties may be provided within a single SMP-integrated fabric device.
