Abstract: Augmenting the functionality of an off-the-shelf additive manufacturing machine, such as a 3D printer, by generating a component design having an autonomy characteristic, and that may impart a functionality to one or more components manufactured by the additive manufacturing machine that is based on an interaction between the component and the additive manufacturing machine. The design includes code for instructing the additive machine to build an ancillary component, such as a cantilever spring, and build the primary manufactured object, and use the cantilever spring to propel the object off the build platform. In this manner the functionality of an off-the-shelf additive manufacturing machine is expanded without physical modification of the machine, and can be implemented remotely to embed additional functionality into designed components that are to be fabricated, for example on spacecraft where physical retrofits are impractical. Other applications include parts and material testing and rapid prototyping.

Abstract: An electrodeless plasma thruster with closed-ring-shaped gas discharge chamber (1, 10) can include a gas discharge chamber (1, 10) closed-ring-shaped in fluid communication with a propellant storage system (10, 70). An antenna (3, 30) can be positioned on the exterior of the gas discharge tube (1, 10). A guide tube (2, 20) can be coupled with the gas discharge chamber (1, 10) at a first end and have a second open end. A magnetic system (7, 50) can be positioned on the second end of the guide tube (2, 20). The magnetic system (7, 50) can be electrically coupled with a power supply. The power supply can be electrically coupled with a power converter (11, 80) and a control module.

Abstract: An electrodeless plasma thruster with close ring-shaped gas discharge chamber (1,10) can include a gas discharge chamber (1,10) close ring shaped in fluid communication with a propellant storage system (10,70). An antenna (3,30) can be positioned on the exterior of the gas discharge tube (1,10). A guide tube (2,20) can be coupled with the gas discharge chamber (1,10) at a first end and have a second open end. A magnetic system (7,50) can be positioned on the second end of the guide tube (2,20). The magnetic system (7,50) can be electrically coupled with a power supply. The power supply can be electrically coupled with a power converter (11,80) and a control module (12,90).
