Equipment - 3D Systems Viper for Stereolithography


The 3D Systems Viper (SLA) is used for photopolymeric layer manufacturing of Epoxy-based resin materials. It is used to support fundamental research and application projects.

The resin is cured by solidifying successive layers with a Nd: YVO4 laser with a wavelength of 354.7nm. The beam produces 100mW of power at the point of convergence with the resin vat.
