| Abstract Scope |
This study explores the application of the infinity-corrected optical system (ICOS) to projection-based 3D printing technology to enhance print area without sacrificing the print resolution. Traditional 3D printer systems utilize finite optical elements that limit the print area due inversely proportional relationship between the print resolution and print area. ICOS, by contrast, employs a configuration that allows for an extended optical path by using parallel beams, which can incorporate additional optical components like mirrors and beam splitters, enhancing functionality. This arrangement facilitates the expansion of UV patterns over larger areas while maintaining high resolution. Experimental comparisons of illuminated image qualities between transmitted and reflected patterns demonstrate a negligible variance, suggesting effective scalability for mass production. A single UV light engine with ICOS can achieve the performance of multiple UV projectors, offering a cost-effective solution for large-scale manufacturing. Further research could vastly impact the future capabilities of 3D printing in industry. |
