摘要： A custom bleaching tray or device with trench and material pocket/reservoir is disclosed. The device comprises a trench to avoid leakage of bleaching material onto the gingiva and a reservoir to precisely hold the bleaching material on the surface of the tooth. A method for forming a 3D-printed custom bleaching tray may include: providing or accessing teeth scan data associated with a patent's mouth; generating a digital model of the patient's mouth based on the teeth scan data, including manipulating the teeth scan data to form: a trench between one or more teeth and a gingiva region of the teeth scan data, and a bleaching material reservoir on a surface of each of the one or more teeth of the teeth scan data; and 3D-printing, based on the digital model, a 3D-printed bleaching tray. A thermoforming process may be applied to the 3D-printed bleaching tray.

摘要： A machine for manufacturing tube elements comprised of tape strips. The machine includes a shaft, a disk mounted to one end of the shaft, a motor coupled to an opposite end of the shaft, and a plate mounted to the shaft. The plate includes a plurality of spools mounted to the plate, where a separate one of the strips is wound on each spool. In one embodiment, the machine further includes a rail positioned adjacent to the disk, a slide slidably secured to the rail and including an end support configured to hold ends of the tape strips, and an indexer configured to pull the slide on the rail away from the disk. The tape strips are unwound from the spools when the indexer pulls the slide in a manner so that the tape strips ride in a spaced apart manner around the disk to form the tube element.

摘要： The invention is generally a 3D printer configured for printing 3D objects using a high-viscosity photosensitive material. The 3D printer may include a fluid retaining assembly which comprises a rotating tank. A printing platform is situated in a manner such that a bottom surface of the printing platform makes contact with the printing solution in the tank. To facilitate printing using the high-viscosity printing material, a scraper assembly may be implemented in order to properly prepare the printing solution onto a surface of the tank. The scraper assembly prepares the material by scraping a layer of the material onto the surface of the tank for facilitating curing of the layer onto the printing platform.

摘要： Embodiments herein relate to 3D printing. In an embodiment, a method for printing an article using a selective toner electrophotographic process (“STEP”) includes successively depositing multiple layers of part material and support material, the layers deposited substantially parallel to a first plane; wherein: a) the multiple layers of part material and support material extend in a perpendicular to the first plane; and b) at least some of the layers of part material and support material are separated from each other to form a gap between the layers of part material and layers of support material; application of heat and pressure to the part material and support material such that a portion of the part material and support material flows into and at least partially fills the gap between the part material and support material.
