According to an embodiment of the present disclosure, a method for manufacturing a 3D structure includes: making a plurality of single piece molds having a same surface shape as a portion of a surface of the 3D structure; making a plurality of exterior members having the same surface as the portion of the surface of the 3D structure by using the respective single piece molds; and forming the 3D structure by connecting the plurality of exterior members.

What is presented is a unit cell comprising a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry arranged to have a coincident central vertex. The cubic cell geometry comprises three orthogonal cell faces that intersect at its central vertex. The tetrahedral cell geometry comprises an arrangement of eight tetrahedral cells that share its central vertex such that each tetrahedral cell shares three coincident edges with three other tetrahedral cells in a cubically symmetric arrangement. The tetrahedral cell geometry is combined with the cubic cell geometry such that all vertices of the tetrahedral cell geometry are coincident with the vertices of the cubic cell geometry.

Described herein are various embodiments directed to rotor devices, methods, and systems. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. A method may include bonding a first layer and a second layer using two-shot injection molding. The first layer coupled to the second layer may collectively define a set of wells. The first layer may be substantially transparent. The second layer may define a channel. The second layer may be substantially absorbent to infrared radiation. A third layer may be bonded to the second layer using infrared radiation. The third layer may define an opening configured to receive a fluid. The third layer may be substantially transparent. The channel may establish a fluid communication path between the opening and the set of wells.

The invention relates to a method for manufacturing a steering wheel comprising a frame, a covering formed by a body, overmoulded onto the frame, and at least one insert, the method comprising steps aimed at: providing at least one recess in the covering, and producing the insert so that an assembly of the insert with the body of the covering allows the recess, to be at least partially covered, wherein the insert is obtained in a single piece with the body of the covering.

An appliance and methods are described that include embodiments of a mandibular advancement or positioning device which can use elastic bands to pull the jaw forward. The appliance has an upper plastic tray conforming to the patient's upper teeth and including 3D printed sets of retention hooks coupled to the upper plastic tray via being encased in plastic, one on the right and one on the left anterior buccal portion of an upper plastic base. The appliance also has a lower plastic tray conforming to the patient's lower teeth including mandibular dentition, and includes having a 3D printed bite pad which opens the bite vertically. The lower tray also has a set of 3D printed plastic retention hooks encased in plastic extending outwardly from the teeth, one on the right and one on the left of the posterior buccal portion of the lower plastic base. Elastic bands of different lengths and strengths are attached to both the top and bottom retention hooks on both sides of the trays to pull the mandible forward for treatment.

A water delivery pipe made from PVC or PVCO and having an inner surface which is rifled. The inner surface of the pipe preferably includes a graphene material. The pipe has improved anti-bacterial properties such that the formation of bacterial biofilms is eliminated or reduced.

Methods of making the pipe are also disclosed.

A lamp includes: a housing in which an accommodating portion for accommodating a sealed member is arranged; a lens which covers the accommodating portion and is bonded to the housing; and a resin bonding material which is in contact with the housing and the lens and bonds the housing to the lens. Besides, the housing includes, as the accommodating portion, a first accommodating portion having an elongated shape, and a second accommodating portion having an accommodating part wider than that of the first accommodating portion, wherein a first abutting surface of the housing and a second abutting surface of the lens in the second accommodating portion are formed in a manner that the respective surfaces thereof have an uneven shape. The resin bonding material is in contact with a protruding surface of the housing and a wall portion of the lens.

The invention relates to a hydraulic tank (10) for storing a hydraulic liquid, comprising a one-piece tank housing (12) which forms a plastic hollow body and is manufactured by a rotational moulding process, wherein the tank housing (12) comprises at least one connection opening (92, 94, 126) at which is arranged a connection element (100, 110, 132) that is releasably connectable to a hydraulic conduit. In order to enable the hydraulic tank to be more cost-effective to produce, the connection element (100, 110, 132) comprises a plastic body which is manufactured by an injection moulding process and is welded together with the tank housing (12). Furthermore, a method for manufacturing a hydraulic tank (10) is proposed.
