摘要:
A mold assembly for forming a film includes a transparent bottom mold, a top mold, a case, and a lighting member. The transparent bottom mold defines a cavity for receiving a work piece and a plurality of liquid compositions. The top mold is matched with the bottom mold to accommodate the work piece between the bottom mold and the top mold. The case receives the bottom mold and the top mold placed therein. Air in the case is exhausted from the case to coat the plurality of liquid composition on the work piece. The lighting member emits light on the liquid compositions to solidify the liquid compositions to form a film on the work piece.

A coating system includes a coating device, a suction device, and a conveyor system. The coating device includes a first holding device including a first surface, a second holding device including a recess and opposite to the first holding device, an o-ring positioned on the first surface. The first holding device couples to the second holding device and a component is held on the first surface. A forming cavity is surrounded by the component, the recess, and the o-ring. Glue is injected into the forming cavity and is formed films over the component.
摘要:
A method of forming a three-dimensional object, is carried out by (a) providing a carrier and a build plate, the build plate comprising a semipermeable member, the semipermeable member comprising a build surface with the build surface and the carrier defining a build region therebetween, and with the build surface in fluid communication by way of the semipermeable member with a source of polymerization inhibitor; (b) filling the build region with a polymerizable liquid, the polymerizable liquid contacting the build surface; (c) irradiating the build region through the build plate to produce a solid polymerized region in the build region, while forming or maintaining a liquid film release layer comprised of the polymerizable liquid formed between the solid polymerized region and the build surface, the polymerization of which liquid film is inhibited by the polymerization inhibitor; and (d) advancing the carrier with the polymerized region adhered thereto away from the build surface on the build plate to create a subsequent build region between the polymerized region and the build surface; (e) wherein the carrier has at least one channel formed therein, and the filling step is carried out by passing or forcing the polymerizable liquid into the build region through the at least one channel. Apparatus for carrying out the method is also described

摘要:
The invention relates to a substrate-based method for forming a three-dimensional object by additive fabrication by coating a liquid radiation curable resin comprising from 30 to 80 wt % of cationically curable compounds on a substrate, contacting the liquid radiation curable resin with a previously cured layer, selectively exposing the layer of liquid radiation curable layer to actinic radiation thereby forming a cured layer, separating the cured layer at the substrate, and repeating the steps a sufficient number of time in order to build up a three-dimensional object.
摘要:
A mold structure for forming a keypad panel includes a mold base, a transparent mold core and a fixed board. The mold base has an opening, a connecting portion around the opening, a containing space extended from the connecting portion, a positioning portion and a groove on the surface of the mold base, and screw holes inside the containing space. The transparent mold cavity has a body, a connecting edge around the periphery of the body and attached to the connecting portion, and a mold of a keypad panel on the surface of transparent mold cavity and exposed from the opening of the mold base. The fixed board has an opening for projecting light onto the transparent mold cavity and through holes around the periphery of the opening for securing screws into the screw holes to assemble the fixed board into the containing space and press the transparent mold cavity.
