The Viper SLA enables customers to choose between standard resolution mode for the best balance of build speed and part resolution, and high-resolution (HR) mode for ultra-detailed small parts and features. In addition, the system builds parts with a smooth surface finish, excellent optical clarity, high accuracy, and thin, straight, vertical walls - ideal for a wide range of solid imaging applications. Technical information: Standard mode is 0.250 +/- 0.025mm (0.010 +/- 0.001in) and layer thickness. Hi-resolution mode is 0.075 +/- 0.015mm (0.0030 - 0.0005in). Build envelope in standard mode, is 250 x 250 x 250mm XYZ (10 x 10 x 10in) Build envelope in high-resolution mode, is 125 x 125 x 250mm XYZ (5 x 5 x 10in). Materials: SI10, SI50, Bluestone
