Abstract

In the rapidly evolving field of additive manufacturing (AM), projection-based 3D printing emerges as a transformative solution to traditional manufacturing constraints. This study introduces a novel approach in projection-based 3D printing, utilizing a unique “infinity-corrected optical system” inspired by microscopy technology. The advanced optical system allows 3D printing to achieve performance comparable to multiple UV projectors while utilizing only a single UV light engine, offering a cost-efficient solution. This method enhances the print speed and expands the printable area, while maintaining the print resolution, addressing the shortcomings in existing 3D printing techniques. By employing a single UV projector along with integrated fixed optical components, this system offers a stable, reliable, and economically viable printing process. This innovation marks a pivotal advancement in mass production, mass customization, and large-area 3D printing, effectively bridging current technological gaps and paving the way for advanced manufacturing systems.
