This product is based on DIW (Direct Ink Writing) printing technology and microfluidic technology. By integrating microfluidic chips, it enables the real - time in - situ generation and precise manipulation of the microstructures of composite materials during the printing process. It can achieve the printing of composite materials with microsphere, coaxial, and component gradient distributions. The printable materials mainly include bio - hydrogels, silicone gels, electronic pastes, etc., and are widely used in fields such as biomedicine, medical devices, and flexible electronics.
