The optical system uses a variable core diameter optical fiber, which can greatly improve the light transmission efficiency and increase the optical subsystem flexibility. The working principle of optical modeling and its theoretical basis are described. Based on the introduction of the optical subsystem of the optical shaping system, the selection and design of UV light source and the design, transmission, coupling and focusing of the core optical fiber are described. technology. The optical subsystem based on variable core optical fiber has the advantages of low cost, small size and high efficiency and has been successfully applied to the low-cost benchtop low-cost rapid prototyping system developed, laying a technical foundation for the further promotion of the system
