The system works by exposing a UV-light sensitive resin to an accurately positioned solid-state UV laser beam.
Wherever the laser beam touches the resin, the material is instantly changed from a liquid into a solid. By solidifying successive layers of material, parts are manufactured.
The system has a typical layer thickness of 0.1mm, but can build in layer as thin as 0.02mm.
The 3D Systems Viper SLA uses a solid state laser producing 100mW of power at the point of convergence with the resin vat.
The laser produces a beam diameter of 0.25mm (+/- 0.025mm) in standard resolution mode and 0.075mm (+/- 0.015mm) in high resolution mode.
In perfect running condition and very well maintained
