摘要： An electrically conductive, flexible, strain resilient product is produced by mixing metal coated carbon nanotube networks with a liquid polymeric resin to produce a liquid mixture, and the mixture is cured to produce the product. The networks may include welded junctions between nanotubes formed by depositing and melting metal nanoparticles on the nanotubes to form the metal coating. After the mixing step the liquid mixture may be deposited on a flexible substrate in the form of an electrical circuit. The mixing step may further include mixing the composite with a volatile solvent to produce a selected viscosity. Then, a three-dimensional printer may be used to print the product, such as an electrical circuit, on a substrate. The product is cured in an atmosphere that absorbs the solvent. The conductivity of the mixture may be adjusted by adjusting the weight percentage of the metal coated carbon nanotube networks from 50% to 90%, but a preferred range is between 75% and 85%.

摘要： Process control parameters are predicted to fabricate an object using deposition. An input design geometry is provided for the object. A training data set includes past post-build physical inspection data for a plurality of objects that comprise at least one object that is different from the object to be physically fabricated; and training data generated through a repetitive process of randomly choosing values for each of multiple process control parameters and scoring adjustments to the multiple process control parameters as leading to either undesirable or desirable outcomes, the outcomes based respectively on the presence or absence of defects detected in a fabricated object arising from the process control parameter adjustments. A machine learning algorithm is trained using the provided training data set and a predicted optimal set of the multiple process control parameters is generated for initiating and performing the deposition process to fabricate the object.

摘要： The disclosure belongs to the technical field of additive manufacturing, and discloses a flexible piezoelectric sensor based on 4D printing and a preparation method thereof. The sensor includes a magnetic part and a conductive part, wherein: the conductive part includes two substrates disposed opposite to each other and a spiral structure disposed between the two substrates. Both the two substrates and the spiral structure are made of conductive metal materials. The magnetic part has a flexible porous structure and is arranged between the two substrates to generate a magnetic field. When the substrate is subjected to external pressure, the spiral structure and the magnetic part are compressed simultaneously, the magnetic flux passing through the spiral structure changes, and the voltage of the two substrates changes, by measuring the voltage change of the two substrates to reflect the change of external pressure, the pressure measuring process is achieved.
