Application of Bossin Photosensitive Resin in Light-Curing 3D Printing

Light-curing 3D printing concept

3D printing, also known as additive manufacturing technologies (AM), is a technique for fabricating physical parts by sequentially adding material layer by layer based on three-dimensional CAD data. Photopolymerization 3D printing technology specifically refers to the process in which photosensitive resin is selectively cured by ultraviolet light under the control of digital signals. After curing, the resin is layered and accumulated step by step until a complete 3D part is formed.

The most significant feature that distinguishes 3D printing technology from traditional manufacturing processes is that it can produce parts with complex shapes and structures without the need for molds or post-processing. In theory, it allows for the fabrication of components made from any material and with any desired structure.

There are four key components in light-curing 3D printing technology: The first is the photosensitive resin, which needs to be stored in a liquid tank for later use; the second is the perforated table, through which light can pass; the third is the laser source, primarily used as the device that emits the required radiation light; and the fourth is the computer, which is used to control the movement of both the laser source and the perforated worktable.

Among these materials, photosensitive resins have become the preferred choice for 3D printing high-precision and advanced products due to their excellent fluidity and photopolymerization properties. To obtain high-performance, photopolymerized 3D-printed parts, it is essential to use photosensitive resins with specific functionalities—such as low volatility, low viscosity, high curing speed, low volumetric shrinkage, and good thermal stability. Moreover, during the molding process and in the equipment used, the materials must also meet requirements such as being non-toxic and non-irritating. This approach enables the simple and automated fabrication of products with superior surface quality, dimensional accuracy, and relatively complex geometries, representing yet another significant breakthrough in the field of additive manufacturing technology.
