SYSTEMS AND METHODS FOR THERMOFORMING DENTAL ALIGNERS

A system includes a plurality of assemblies each configured to support a dental mold and a material, a heating system configured to heat the material, a forming system configured to form a chamber encompassing the dental mold and at least a portion of the heated material, and to cause the heated material to form over the dental mold, and a conveyor system configured to move the plurality of assemblies from a loading area to the heating system, from the heating system to the forming system, and from the forming system to an unloading area.

Method and device for producing a 3-D substrate coated with a laminate

A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.

THERMOFORMING MULTIPLE ALIGNERS IN PARALLEL

Embodiments relate to thermoforming multiple aligners simultaneously. In one embodiment, an aligner manufacturing system includes a plate, a heating section, and a thermoforming chamber. The plate is configured to secure a first mold of a first dental arch and a second mold of a second dental arch. The heating section is configured to heat a sheet of plastic to generate a heated sheet. The thermoforming chamber is configured to simultaneously thermoform the heated sheet over the first mold of the first dental arch and the second mold of the second dental arch to form a first aligner shaped to fit the first dental arch and a second aligner shaped to fit the second dental arch.

Rapid response fabrication of marine vessel platforms
20200269530 · 2020-08-27 ·

Marine vessels, including combatant (naval) vessels are produced inexpensively without requiring the use of as many skilled personnel as is conventional. The vessel produced has a high strength metal truss structure (both above and below the water line) capable of carrying major hull loads. A number of curved or doubly curved composite (e. g. GRP) panels produced by vacuum assisted resin transfer molding are fastened by bolts, marine adhesives, and/or rivets to the below water line portions of the truss structure where necessary to handle slamming loads and to reduce water resistance and wake. Substantially flat composite pultruded panels are fastened to the truss structure both above the water line, and below the water line where the resistance to slamming loads and reduction of water resistance and wake are not critical. Necessary equipment is installed within the open truss volume before the above-water-line panels are fully installed.
