Iterative 3D printing with photopolymer resin and precision optics now benefit from a new material. 

1.The demand for precision manufacturing has surged, and traditional heat-curing resins have their limitations.
Products such as 3D optical components, micro sensors, and automotive optical lenses are continuously becoming smaller and more refined. Traditional high-temperature curing silicone resins are prone to deformation, air bubbles, and significant light transmission loss. The high-temperature baking process also restricts the use of plastics and flexible substrates together. The market urgently needs silicone resin materials that can be molded at low temperatures and quickly. 

2. Modification of photosensitive groups, achieving ultraviolet light-based low-temperature curing in seconds
By introducing vinyl photosensitive structures into the molecular side chains, the new photopolymer resin does not require platinum-based high-temperature catalysis. Under normal temperature conditions, it can complete cross-linking and molding within tens of seconds after being exposed to ultraviolet light. The curing process does not produce small molecule volatiles, and the molding shrinkage rate is less than 0.5%, perfectly adapting to high-precision microstructure printing and ultra-thin optical coating coating processes. 

3. High light transmittance and UV resistance, suitable for various types of optical precision components
The modified silicone resin has a light transmittance of over 96%. It does not yellow or lose its transparency even under long-term UV exposure, and its thermal expansion coefficient is highly matched with glass and wafers. It can be used for LED chip packaging, AR optical lenses, under-screen fingerprint bonding glue, and micro-lens arrays, addressing the industry pain points of optical components' high-temperature aging and light attenuation. 

4. Processing efficiency has been significantly enhanced, and it is compatible with automated mass production lines.
The photopolymerization process eliminates the need for long periods of high-temperature baking, and the production efficiency per batch has increased by more than 4 times. It is suitable for continuous coating on assembly lines and high-speed 3D printing equipment. The material storage stability is strong, with a long-term storage stability period of over 6 months at room temperature. There is no need for low-temperature and light-shielded storage, which significantly reduces the factory's storage and energy costs, and quickly opens up the incremental market for precision optoelectronic manufacturing.
