A three-dimensional (3D) printer includes an acoustophoresis device having at least a first inlet, a first outlet, and a channel defined between the first inlet and the first outlet. A piezoelectric device is adhered to a surface of the acoustophoresis device to generate sound waves within the channel. A printhead is connected to the first outlet of the acoustophoresis device, wherein a solution comprising anisotropic particles is delivered to the at least first inlet and wherein the anisotropic particles are organized into one or more columns along an axis parallel to a direction of flow of the solution by standing acoustic waves generated by the piezoelectric device, wherein the at least one column of anisotropic particles is aligned with the first outlet, and wherein the first outlet is in fluid communication with the printhead to deliver one or more columns of ordered, anisotropic particles to the printhead.

A system and process for bonding involves a pocket made into one article is used to secure that article to another using a flowable, curable material (e.g., resin) which during saturation enters through a passageway and at least partially fills the void. When the article is cured, the article is bonded to another article to which resin has also been applied since the void (now containing cured material) is larger than the passageway.

The present teachings contemplate additive manufacturing of articles, such as articles made by layer-by-layer deposition of one or more reformable resin polymeric feed material. In particular the invention relates to a feed material system for preparing an article by additive manufacturing, comprising one or more preform elements of a feed material (i) formed of a reformable resin polymeric material including a polymer backbone having a plurality of repeat units each having ether linkages (e.g. derived from an epoxy containing reactant), and optionally one or more pendant hydroxyl moeities; and (ii) which is capable of transforming from a generally non-tacky first state to a second state in which the material is softened, upon application of heat, relative to the first state and is at least partially tacky in the second state to permit it to adhesively bond to a surface upon which it is deposited for forming a layer on the surface, to a third state in which the material is harder than when in the second state but remains able to further soften upon application of heat, wherein the resulting adhesive bond is substantially devoid of any cross-linking between the layer and the surface, and wherein the one or more elements of the feed material are in a form adapted to be dispensed by an additive manufacturing apparatus.

A method for forming a lens housing containing a polymeric lens including inserting a mandrel having a distal face with negative features of the desired polymeric lens into a cylinder and filling a reservoir formed between the distal face and a distal end of the cylinder with a curable polymeric lens material. The curable polymeric lens material is cured in place within the reservoir thereby forming the desired polymeric lens. The proximal surface of the polymeric lens is formed and shaped by the distal face of the mandrel, while the distal surface of the polymeric lens is dependent upon the amount of the curable polymeric lens material placed in the reservoir and the volume of the reservoir.

A method for treating a surface of a fibre composite component, wherein an abrasive removal of the surface of the fibre composite component takes place by blasting a removing agent transported by a gaseous transporting fluid onto the surface of the fibre composite component by a feed nozzle and a suction extraction of the removing agent and material removed by the removing agent takes place by an extraction nozzle arranged in the region of the feed nozzle.

Disclosed embodiments provide an electrofusion pipe coupler with mechanical support. The electrofusion pipe coupler comprises a coupler housing. A wire is configured and disposed within the housing. Electrodes are affixed to the coupler housing and in electrical contact with the wire. A threaded pattern is formed in an outer surface of the coupler housing. Gripping wedges are affixed to the coupler housing. Each gripping wedge extends from the coupler housing. A nut is attached to the coupler housing, engaging with the threaded pattern, and compressing the wedges against the connecting pipes. This serves to provide axial load transfer from the connecting pipes to the coupler housing via the wedges, thereby providing improved mechanical stability for such pipe assemblies.
