Abstract

The invention discloses light-cured printing equipment and a method for forming a three-dimensional structure in photosensitive hydrogel according to an image stored in a computer. The light-cured printing equipment comprises a digital projection unit used for projecting the image into a photosensitive hydrogel layer, a photosensitive hydrogel curing unit used for providing the photosensitive hydrogel to form the photosensitive hydrogel layer and curing the photosensitive hydrogel in the photosensitive hydrogel layer according to the projected image layer by layer and a computer control unit used for providing the image to the digital projection unit and controlling imaging position of the projected image in the photosensitive hydrogel layer, wherein the photosensitive hydrogel curing unit consists of a guide rod and a bearing sheet which moves along the guide rod, and the lower surface of the bearing sheet is used for limiting the upper liquid level of the photosensitive hydrogel layer. The light-cured printing equipment is capable of printing the three-dimensional structure with high accuracy and high speed.

Description

technical field

[0001] The present invention relates to 3D printing technology, more specifically, to photocuring printing equipment and methods. Background technique

[0002] 3D printing is a kind of rapid prototyping technology, also known as "additive manufacturing" technology (Additive process). At present, the materials that can be used for 3D printing are very limited, mainly materials that are easy to shape such as plastics and ceramics, and photosensitive materials that can be photopolymerized.

[0003] 3D bioprinting is mainly used in the field of tissue engineering, that is, the biological scaffold is first printed, and then the cells are cultured and expanded and seeded on the biological scaffold. The cell-bioscaffold complexes were cultured in vitro and then transplanted into the body. In this system, cells cannot be planted inside the bioscaffold, and relatively complex tissues and organs cannot be constructed, especially the constructed tissues and organs can...
