Stereolithography, SLA, is a part of the manufacturing technology of vat polymerization. This means a light source (laser) is used to cure liquid resin into a hard plastic.

The Form 2 is the only 3D printer that the Prototype Lab has that is an SLA printer. It utilizes the Upside Down or Inverted orientation.[[File:InvertedSLA.png|302x302px|thumb|right|Inverted SLA Process]]

The resin tank has a clear bottom with a surface the resin will not stick to. This allows the resin to cure against the bottom of the tank.

The build platform is lowered into the resin until it is hovering above the bottom surface of the tank, as far away as the height of the layer to be constructed.
