Abstract

A mould-forming and sacrificial materials are printed into a plurality of layers. The sacrificial material is removed to leave a void defined by a mould structure formed by the mould-forming material. The void is filled with a part-forming material to form the part defined by the shape of the mould structure. The mould structure is removed from the part to free the part from the mould structure. According to a further method, the part-forming material serves the purpose of supporting the mould-forming material and then forming the part. In this case, the part-forming material can be printed together with a mould-forming material as described above and are then heated to a temperature of approximately 700° C. to activate a binder and then heated to a temperature that melts the part-forming material.

Abstract

A method for forming a component includes providing a first layer of a mixture of first and second powders. The method includes determining the frequency of an alternating magnetic field to induce eddy currents sufficient to bulk heat only one of the first and second powders. The alternating magnetic field is applied at the determined frequency to a portion of the first layer of the mixture using a flux concentrator. Exposure to the magnetic field changes the phase of at least a portion of the first powder to liquid. A change in power transferred to the powder during a phase change in the powder is calculated to determine the quality of component formation.

Abstract

The invention provides a flux pump that includes a plurality of superconducting materials arranged to form at least one superconducting loop, at least one of the components being made of a superconductor that includes particles made of a superconductive material and a conductive material selected to be driven to a superconductive state when in proximity to the superconductive material, an unbroken section of the conductive material being located sufficiently close to a plurality of the particles to be driven to a superconductive state by the superconductive material.

Abstract

The invention provides a variable impedance device including a first bus bar refrigeration system, a first bus bar thermally connected to the first bus bar refrigeration system to be maintained at a target bus bar temperature by the first bus bar refrigeration system, a variable impedance component refrigeration system, a variable impedance component electrically connected to the first bus bar and thermally connected to the component refrigeration system, a variable impedance component may be at least partially made of a material that is superconducting below a critical temperature and may be maintained at a target component temperature, wherein the target bus bar temperature may be between the 300K and critical temperature and the target component temperature may be below the critical temperature and a second bus bar connected to the variable impedance component so that current flows between the first and second leads through the variable impedance component.
