A microwave-induced heating of CNT filled (or coated) polymer composites for enhancing inter-bead diffusive bonding of fused filament fabricated parts. The technique incorporates microwave absorbing nanomaterials (carbon nanotubes (CNTs)) onto the surface or throughout the volume of 3D printer polymer filament to increase the inter-bead bond strength following a post microwave irradiation treatment and/or in-situ focused microwave beam during printing. The overall strength of the final 3D printed part will be dramatically increased and the isotropic mechanical properties of fused filament part will approach or exceed conventionally manufactured counterparts.

Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil is preferably a freestanding multilayered foil structure made up of alternating layers selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually any environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt or soften the joining material, which upon cooling will form a strong bond, joining two or more bulk materials. If no joining material is used, the foil reaction supplies heat directly to at least two bulk materials, melting or softening a portion of each bulk, which upon cooling, form a strong bond. Additionally, the foil may be designed with openings that allow extrusion of the joining (or bulk) material through the foil to enhance bonding.

A device for connecting two tubular vessels together in a side-by-side or tangential manner is disclosed. The device has an annulus and at least one series of fingers connected to and extending away from the annulus. In the preferred embodiment there are two sets of fingers connected to and extending away from the annulus in opposite directions. Each finger is preferably biased into an arcuate shape. In use, a deployment apparatus is used to constrain the fingers of the device to be in a relatively planar configuration. The deployment apparatus containing the device is placed between and in contact with the two tubular vessels so that one tubular vessel is above the device and one tubular vessel is below the device and so that the fingers of the device come into contact with the tissue of the vessels. As the fingers penetrate the vessels the constraint on the fingers is removed so that the fingers can assume their biased arcuate shape. In this way, the fingers penetrate and grasp the tissue of the vessels so that the device grasps the vessels and pulls the vessels toward each other.
