This is the latest technology in the stereolithography industry, and once again FineLine helped pioneer its introduction. This machine does for large parts what the Viper did for small parts—it represents a significant step up in quality and resolution. See for yourself! The ‘Pro uses a Viper-HR-like 0.005" laser beam diameter for the borders–the outsides of the parts that you see, feel, and measure–and a thicker, 0.030" diameter beam for the insides of the part to image it much faster. It is set apart from the older large machines by its advanced imaging system, which allows the beam path to be shorter, leading to better control over vector drawing.
