The Custom Print Design System leverages advanced large language models (LLMs) to enable users to create unique and personalized print patterns. Designs can be generated using text-to-image or image-to-image models, such as Stable Diffusion (SD). The system also incorporates 3D virtual technology to allow users to preview their designs on various items, including T-shirts, polo shirts, and bags. Once a design is finalized, the production line efficiently manufactures and ships the products directly to consumers.
