Embodiment Construction

[0044] System Hardware Design

[0045] According to different application devices or systems, the trough polymerization process can choose LED-type point light source, linear light source, planar light source or a combination thereof as its system light source.

[0046] Depending on the position of the light source relative to the resin tank, the model or workpiece platform of the upper exposure system sinks into the resin liquid surface, and the fresh resin material flows through a part of it; while the lower exposure type system absorbs the fresh resin material and rises. The height of the resin tank in the upper exposure system should be equal to the height of the model to be built, and filled with non-reusable resin, so that the separation force problem in the lower exposure system will not occur.

[0047]Huang (2001) found that the lower exposure type system will introduce a load, and thinks that the separation force will increase linearly with the increase of the area. ...

Abstract

A method of photo-curing a photo-sensitive resin is disclosed in the present invention. The method includes the following steps: generating a sub-pixel pattern having an outer contour region and an inner contour region based on a vector file taken from a cross-section of a model; providing the sub-pixel pattern to a photomask module, wherein the photomask module includes a panel having a pixel matrix including plural square pixels, each of which includes three color-filtered sub-pixels; flood-filling color in each of the color-filtered sub-pixels to distinguish the outer contour region from the inner contour region; and exposing the photo-sensitive resin to a light source emitting a light passing through the panel.

Description

technical field [0001] The present invention relates to a manufacturing method of a laminate, that is, a method of photocuring resin. Background technique [0002] Tank polymerization is a result of an array of additive manufacturing (AM) processes that selectively cure liquid resin in tanks by photoactivated polymerization, or photocuring. [0003] The Vat Polymerization Process (VPP) can achieve high-precision speed ratio and excellent surface treatment, but it does not require the use of high-power lasers or inert gas to build chambers such as AM based on powder technology. VPP preparations can include rapid embryonic product design evaluation, indirect mold tooling, such as for jewelry or dental implants; direct digital fabrication of niche or personalized medical devices, such as dental aligners or hearing aids . [0004] Currently commercially available VPP systems use vector-to-vector scanning laser beams, or digital light processing (DLP) projectors, which can be u...
