Disclosed are a three dimensional injection molding apparatus and an injection molding method which are capable of manufacturing an injection molded product having patterns, colors, and textures which are high quality by injection molding after completely removing a gas included in a melted resin, and transferring a surface layer for expressing the patterns, colors, and textures to the injection molded product.

A method for manufacturing an object is disclosed. The method includes the step of obtaining a preform of the object, with the preform having a first panel having a planar portion and at least one second panel. The second panel has an orientation which is different from that of the first panel. The planar portion of the first panel of the preform is thermoformed so as to have a protruding element. The thermoforming is done in a selective manner such that the at least one second panel is not thermoformed. The invention is also directed to a thermoforming device for performing the thermoforming.

Provided is a method of three-dimensionalizing a planar image, including: a shaping step (S1) of shaping a main body (6) three-dimensionally representing a planar image of a form of an object (1) to be shaped; a coating step (S2) of applying a base material to a surface of the main body (6); a digitizing step (S3) of creating image data of the object (1) to be shaped based on the planar image; a sticker creating step (S4) of creating a wrapping sticker (8) having printed thereon the image data of the object (1) to be shaped; and an affixing step (S5) of affixing the wrapping sticker (8) to the surface of the main body (6).

A package for retaining a food item includes a tray with a base connected to at least one sidewall. The sidewall extends away from the base to a rim to define an inner chamber. The tray is made of a fluid impermeable material to retain fluids in the inner chamber. The package also includes a shelf made of the fluid impermeable material that is removably supported in the inner chamber such that the shelf is spaced apart from the base of the tray to permit an absorbent pad to be positioned therebetween. The shelf is configured to support the food item in the inner chamber separated from the absorbent pad.

A vacuum thermoforming apparatus including: a molding machine on which a window base material is mounted; and a pressure supply machine coupled to the molding machine and configured to supply a pneumatic pressure toward the molding machine. The molding machine includes a mounting part having a curved surface-shaped mounting surface, and a coupling part having a structure for coupling with the pressure supply machine and a curved portion along the shape of the mounting part. The pressure supply machine includes: a cover part facing the mounting surface; and a side wall extending from the cover part to define an inner space in the pressure supply machine, the side wall having a curved upper surface so as to engage with the coupling part.

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.

The invention is a system and method for forming a dental appliance. A control module may be configured to receive data concerning a dental model and determine a toolpath for creating a pre-cut substrate based on the data. A cutting module may be configured to create the pre-cut substrate based on the toolpath. A forming module may be configured to apply a second substrate to the pre-cut thermoforming substrate received from the cutting module and form a dental appliance from the pre-cut substrate and the secondary substrate. The method may include receiving data concerning a dental model, determining a toolpath for cutting a substrate into a pre-cut thermoforming substrate based on the data, pre-cutting a first substrate based on the toolpath to form a pre-cut substrate, applying a second substrate to the pre-cut substrate, and thermoforming a dental appliance from the pre-cut substrate and the second substrate.
