A manufacturing method for a pressure tank includes disposing a preform, in which a fiber layer is formed on an outer surface of a liner that forms an internal space of a pressure tank, within a mold, and rotating the preform in a circumferential direction within the mold with a central axis of the preform as a rotation center while resin is injected toward the preform disposed within the mold from a gate.

A method of providing high-speed three dimensional (3D) printing is described. The method includes producing at least one three dimensional (3D) printed part. Producing the 3D part includes continuously constructing to extend outwardly a diameter of a rotating cylindrical core via continuous deposition of a layer, and defining a first pattern in the continuously deposited layer corresponding to a cross-section of the at least one 3D printed part.

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.

A printing system for producing at least one three dimensional (3D) printed part is described. The printing system includes a deposition system configured to continuously deposit a layer onto a cylinder to outwardly extend a diameter of the cylinder, wherein the layer comprises a first pattern. The printing system also includes a rotating system configured to rotate the cylinder, and a control system configured to synchronize the deposition system with the cylinder.

A rotatable and shrinkable platform for a 3d printer system can include multiple segments disposed next to each other around the axis of rotation. The segments can move between a printing configuration and a shrunk configuration. In the printing configuration, the segments are continuously and smoothly disposed next to each other to present a printing surface suitable for printing. In the shrunk configuration, the segments are overlapped to break the adhesion of a printed object with the platform to facilitate the removal of the printed object from the platform.

The invention relates to non-woven protein fibers and to methods for forming and producing the same. In certain embodiments, the invention provides a method of processing a protein comprising dissolving a protein in a solution, optionally removing any insoluble materials from the solution, and spraying the solution under an applied pressure. In other embodiments, the protein can be derived from a range of sources, including but not limited to arthropod silks, animal keratin (e.g. hair and wool), tissue elastin, collagen, resilin, and plant protein. In certain embodiments, the methods of the invention are an alternative to electrospinning methods known in the art.

Simulated tissue structures for practicing surgical techniques and methods of manufacturing those structures are provided. In particular, a realistic organ model or simulated tissue portion for practicing the removal of a tumor or other undesired tissue followed by suturing a remnant defect as part of the same surgical procedure is provided. The simulated tissue structures include a polyp simulation having a suturable mesh layer that is separable from a defect layer. A simulated colon model with interchangeable and suturable tissue pods is also provided as is a fully suturable rectum model and a rectum model with integrative suturable and removable polyp zones.
