Support substrates are used in certain additive fabrication processes to permit processing of an object. For additive fabrication processes with materials that are sintered into a final part, a multi-layer support substrate of interleaved support and interface layers is fabricated to support an object while reducing an impact of friction on shrinkage of the part during the sintering process.

A method of detecting faults and ensuring integrity of membranes having magnetically functionalized particles, including moving a magnetometer over the membrane to measure at least one magnetic property, mapping the location of the measured properties, identifying anomalies among measured properties including the location of such anomalies, and repairing the membrane at the location where anomalies are identified.

A method for producing a composite component and to a composite component for a motor vehicle locking system, consisting of a plastic material and a metal material, the composite component being producible from granules of a plastic material with at least one metal additive admixed thereto.

A lightweight liquid metal composition and a method for producing a lightweight liquid metal composition. The composition includes: a liquid metal inclusion; a low-density phase including a plurality of particles; and an elastic polymer. The method includes: combining a low-density phase with a liquid metal to produce a multiphase liquid metal (LM), the low-density phase including a material having a density less than a density of the LM; mixing the multiphase LM with an elastomer to produce an emulsion; and curing the emulsion to produce a lightweight LM composition.

An apparatus for forming a weld between a first portion of a biocompatible conductive thermoplastic material and a second portion of a biocompatible conductive thermoplastic material comprises a first electrode, a second electrode, and a structure for holding said first and second electrodes in opposition to one other with a space therebetween for receiving said first portion and said second portion in contact with one another. The structure is electrically non-conductive and an electrical circuit comprising a power source and a switch arranged such that closure of said switch applies a voltage potential across said first electrode and said second electrode so as to generate heat via electrical resistance, the heat being sufficient to melt regions of said first and second portions.

Herein disclosed is a method of making a fuel cell including forming an anode, a cathode, and an electrolyte using an additive manufacturing machine. The electrolyte is between the anode and the cathode. Preferably, electrical current flow is perpendicular to the electrolyte in the lateral direction when the fuel cell is in use. Preferably, the method comprises making an interconnect, a barrier layer, and a catalyst layer using the additive manufacturing machine.

An apparatus is disclosed to create a breakaway junction for 3D printed parts. Powder is spread along a target zone, such as a build bed. A liquid functional agent is selectively dispensed upon the powder to form a 3D object, a supporting part, and the breakaway junction between them.

Provided is a three-dimensional object producing method that includes applying an object forming liquid to powder including a base material and an organic material to form a solidified product, and removing the powder deposited on the solidified product from the solidified product using a powder removal liquid including an organic solvent. The following formulae are satisfied
