Abstract: A Z-axis leveling system of an additive manufacturing system, the Z-axis leveling system comprising a base, a build platform, and a vertical actuator mechanically connected to the base. The vertical actuator further comprises a height adjuster platform, at least one vertical guide disposed on the height adjuster platform, a motorized transmission unit disposed on the height adjuster platform and connected to a vertical post platform, at least one vertical post mechanically coupled to the vertical post platform and a base platform connected to the base.

Abstract: An additive manufacturing system for manufacturing a component, the additive manufacturing system comprising a frame, an additive manufacturing machine disposed on the frame, a processor disposed on the frame and electrically coupled to the additive manufacturing system, a memory unit electrically coupled to the processor and containing instructions to control the additive manufacturing system.

Abstract: A dynamic gas flow system used in additive manufacturing systems, the dynamic gas flow system comprising at least one gas inlet, at least one gas outlet, at least one bypass gas inlet, a dynamic flow surface, and a gas flow management system to provide feedback on conditions in the build chamber to adjust operation of the dynamic gas flow system.

Abstract: A leaf spring assisted opener for a folding tool such as a folding knife. The folding tool includes tool pivotally carried by a handle. The tool defines a tang at the proximal end. A leaf spring is carried within the handle for assisting in the opening of the tool. The leaf spring defines an elongated, arcuate configuration having a distal end adapted to engage the tang of the tool. When in the closed orientation, the leaf spring is biased toward the tang of the tool, thus holding it in the closed position. The tang of the tool defines a shoulder strategically positioned such that as the tool is pivoted from the closed position, the leaf spring eventually engages the shoulder and begins to release the tension in the leaf spring. At this point, the tension in the spring serves to open the tool the remainder of the rotation.

Abstract: A folding knife including an elongate handle and blade. A tang of the blade is pivotally connected to the handle proximate the front end of said handle such that the blade is rotatable about a rotational axis. A pin is positioned on and extends from the tang of the blade. The pin is spaced apart from the rotational axis. The folding knife also includes a bias element housed within the blade cavity. The bias element has a free end. In operation, a portion of the bias element is in continuous urging contact with the pin to assist in the movement of the blade into its opening position.
