In an example method for forming three-dimensional (3D) printed electronic parts, a build material is applied. An electronic agent is selectively applied in a plurality of passes on a portion of the build material. A fusing agent is also selectively applied on the portion of the build material. The build material is exposed to radiation in a plurality of heating events. During at least one of the plurality of heating events, the portion of the build material in contact with the fusing agent fuses to form a region of a layer. The region of the layer exhibits an electronic property. An order of the plurality of passes, the selective application of the fusing agent, and the plurality of heating events is controlled to control a mechanical property of the layer and the electronic property of the region.

A photocurable resin may comprise piezonanoparticles. The piezonanoparticles may comprise functionalized barium titanate (f-BTO), functionalized lead zirconate titanate (f-PZT), or functionalized aluminum nitride (f-AlN). The photocurable resin may further comprise a photo-initiator, a photo-absorber, or PEGDA 700.

The present disclosure relates to a polymeric blend composite comprising Poly Ether Ketone/Poly-(2,5-Benzimidazole) containing pre-treated multi walled carbon nanotubes (MWCNTs) between 0.5 to 5 wt % were melt processed on a twin-screw extruder and granules so obtained were injection molded to determine heat deflection temperature (HDT) of these composites and storage modulus using DMA. It was found that HDT and storage Modulus for so produced reinforced blends were unexpectedly extremely high as compared to PEK/ABPBI blends without MWCNTs.

In an example, a method is described that includes building a first layer of a three-dimensional heterogeneous object in a first plurality of passes of an additive manufacturing system. An electronic component is inserted directly into the first layer. The electronic component is then fused to the first layer in a second plurality of passes of the additive manufacturing system.

A liner for a crisp plate includes ceramic nanoparticles and a polymer material combined with the ceramic nanoparticles to provide a mixture. A network of carbon nanotubes is embedded within the mixture to form a composite matrix, wherein the carbon nanotubes are unidirectionally aligned within the composite matrix.

A method for forming a graphene-reinforced polymer matrix composite is disclosed. The method includes distributing graphite microparticles into a molten thermoplastic polymer phase; and applying a succession of shear strain events to the molten polymer phase so that the molten polymer phase exfoliates the graphite successively with each event until at least 50% of the graphite is exfoliated to form a distribution in the molten polymer phase of single- and multi-layer graphene nanoparticles less than 50 nanometers thick along the c-axis direction.

Apparatus and methods for mixing and dispersing a dispersed phase in a medium comprise a rotating surface for receiving the medium and an atomizing apparatus positioned at the rotating surface for depositing aerosolized constituents of the dispersed phase into the medium. The medium is made receptive and the dispersed phase is aerosolized. Constituents of the aerosolized dispersed phase are deposited into the receptive medium to form a compound or composite. The medium may be deposited onto a rotating disk, and the dispersed phase may be sprayed onto the disk. A thin film can be generated on the disk to transfer, distribute, and disperse the dispersed phase. Liquid ligaments formed at the edge of the rotating disk further transfer, distribute, and disperse the dispersed phase into the medium. Ligaments may be broken into aerosols or deformed by attenuation/drawing to further promote transfer, distribution, and dispersion. A bulk composite/compound may be collected.

The invention relates to a thermoplastic composition used for forming articles having both high gloss and excellent resistance to mar, scratch and/or abrasion. The composition contains very high levels of nano-sized inorganic additives, such as alumina, silica and titanium dioxide. Acrylic polymer compositions, such as Arkema's PLEXIGLAS® resins, with 5 to 25 weight percent of sized fumed silica are a preferred embodiment of the invention, especially when combined with a dye or pigment.

The present invention relates to a method of making a biocompatible micro-swimmer, the method comprising the steps of: providing a photo cross-linkable biopolymer solution; adding magnetic particles and a photo initiator to the photo cross-linkable biopolymer solution to form a 3D-printable solution; applying a laser with a variable focus directed at the 3D-printable solution; varying the focus of the laser through the 3D-printable solution to form the biocompatible micro-swimmer with a predefined shape; and applying a chemical linker to the biocompatible micro-swimmer having the pre-defined shape. The invention further relates to such a micro-swimmer and to a method of using such a micro-swimmer.
