On January 29, the Japan 3D Printing Additive Manufacturing Exhibition (TCT Japan) was held in Tokyo, where Goertek Inc.'s subsidiary Goertek Optics Technology Co., Ltd. made its debut and launched its self-developed DLP 3D printing light machine module, achieving a new expansion in the optical field. With the rapid development of the 3D Printing Industry and the increasing demand for high-precision printing, the optical device modules used in 3D printing equipment face higher performance requirements. Accurate light field control helps reduce printing errors in 3D printing light machines, improving the quality and consistency of printed products.
