A method of thermoforming a printed two-dimensional (“2D”) image over a three dimensional (“3D”) model that is not distorted when applied to the model and that need not be distorted in order to have the proper appearance on the model.

Implementations describe systems and methods for manufacturing and performing quality assessment of dental appliances. In one embodiment, a method of manufacturing a dental appliance comprises receiving, at a holder, a feature of the dental appliance, the feature comprising a first surface having a first shape, wherein the holder holds the feature of the dental appliance at a reference position. The method further includes automatically placing an object against the feature at the reference position using a robot arm, wherein the object comprises a second surface having a second shape that mates with the first shape. The method further includes applying pressure to press the object against the feature of the dental appliance and bonding the object to the feature of the dental appliance while applying the pressure.

The invention disclosed herein is an automotive acoustic panel including a porous sound-absorption material made from a polymer and an expanded perlite. One or more silane compounds may be coupled or coated onto the expanded perlite while a coupling agent and a chemical foaming agent may additionally be added to the automotive acoustic panel.

A sheet expressing a good tactile sensation and a molded product thereof. By configuring a resin sheet including hairlike bodies arranged regularly on at least one surface of an underlayer in which a continuous phase is formed without any structural boundary between the underlayer and the hairlike bodies, and the underlayer and the hairlike bodies have at least partially a crosslinked structure, a molded product expressing a good tactile sensation is obtained.

Provided is a biodegradable resin composition that exhibits excellent biodegradability even in a molded product having a large thickness, has excellent mechanical properties, and is economically advantageous, and a molded product using the same. The molded product is provided using an inorganic substance powder-containing biodegradable resin composition including: a biodegradable resin and an inorganic substance powder in a mass ratio of 10:90 to 70:30, in which the biodegradable resin is a cellulose acetate-based resin and the inorganic substance powder is heavy calcium carbonate.

A rubber sole thermo-molding machine includes a lower mold seat disposed on a hydraulic actuator of the machine seat. The lower mold seat ascends and descends with respect to the upper mold seat according to the hydraulic actuator, allowing the lower upper molds to close and open. The upper mold seat moves between a normal position and a tilt position according to the turning mechanism. The middle plate horizontally moves between the upper and the lower mold seats, and has a push mechanism connected with the middle frame. When the pin of the middle frame and the fasten unit on the push mechanism are separated, the middle frame is stacked on the middle plate or the lower mold to move, facilitating the cleansing and material-feeding operations. The user can cleanse the upper mold without being hindered by the middle frame, assuring the safe and smooth process.

Systems and methods for forming 3D plastic parts that are cost effective in low volume, have excellent fit and finish, and use many components from 2D construction are disclosed. The systems and methods involve selecting a design and modelling the design. The design comprises 2D and 3D components of plastic parts. A 3D forming buck corresponding to the 3D component is manufactured. At least one of a 2D part and the 3D forming buck may be heated. The 2D part may be loaded onto the 3D forming buck for a predefined period of time. The 3D part formed after the loading may be separated from the 3D forming buck. The 3D part is the 2D part generally having taken the shape of the 3D forming buck. The 3D part may be cooled to obtain an end product.
