Stereolithography is a light-based process that builds individual layers of a model with liquid polymer, hardened by a laser beam. The laser is directed and controlled by two galvonometers. After each layer, the resin tank peels away to release the hardened material. The build platform then moves up from 25 to 100 microns, depending on the chosen layer height, to prepare for the process of solidifying the next layer. The part appears to be built upside down, which is called inverse stereolithography.
The Form 2 contains a blue 405 nm laser. Custom circuitry activates the laser in timed bursts, generating the energy to turn the photopolymer from liquid to solid.
As the laser travels along the optical pathway, it is reflected by two rapidly oscillating, finely-tuned mirrors which accurately position the laser. This control hardware sweeps the laser repeatedly across the build platform hundreds to thousands of times per second with submillimeter accuracy.
The underside of the replaceable resin tank is an optically transparent window. Sitting at the bottom of the tank is a layer of clear, non-stick silicone, which allows the laser beam to pass into the tank of resin. The non-stick surface serves as a substrate for the liquid resin to cure against, allowing for the gentle detachment of newly-formed layers.
An autoclavable, Class 1 biocompatible resin, Dental SG is designed for printing precise surgical guides and similar devices.
Dental SG Resin causes the resin tanks to cloud and wear faster than other Formlabs resins. This clouding will eventually have an effect on the accuracy of prints. Use a new resin tank with each new Dental SG resin cartridge. For extremely high accuracy, switch resin tanks more often.
For the Grey resin, the guide is to change every 2 liters of resin, but customers can experience longer usage per tank.
One tank lasts for about 2 liters of resin. With a separate tank for each individual resin color, switching materials is as easy as sliding in a new tank.
The smooth matte finish of standard Grey Resin shows details exceptionally well. It is ideal for a variety of dental applications such as orthodontic, diagnostic, and educational models as well as for vacuum-forming aligners or other appliances. When used with a clear separator, Grey Resin can also be used to make retainers.
