How Does SLA Work?

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.


1. The Laser

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.

2. The Galvonometers

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.

3. The Resin Tank

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.

The Curing Process
As the laser contacts a thin layer of resin it chemically hardens, bonding with nearby layers, creating a fully dense, watertight part.

The Formlabs Ecosystem

Formlabs has created a complete, end-to-end system that allows users to 3D print from the convenience of their desktop.
File Processing with PreForm
3D Printing on the Form 2 starts with PreForm, a software package designed to prepare any STL or OBJ for printing. PreForm has several
functions, two of which are essential to quality printing: orientation and support generation. Both of these functions have been automated in
PreForm, allowing users to perform these complicated tasks quickly and reliably. PreForm also automatically repairs files if there are any
issues, ensuring your model’s geometry prints successfully. Once a file has been quickly uploaded to the printer via usb, you can disconnect
your computer, allowing the system to run alone or even overnight. PreForm doesn’t cost anything.
Material Properties
Once a file has been prepared for 3D printing, a specific resin type must be selected for the print. There is a growing library of acrylate
photopolymer resins in two categories: Standard and Functional Standard resins feature tensile strength comparable to monolithic ABS in a variety of shades and transparencies useful for prototyping. Functional resins allow designers to take advantage of material properties for specialized applications, such as flexibility or clean burnout properties for investment casting. With multiple light-blocking resin trays, materials can be swapped in seconds and stored near the printer.
Finish Kit
After a part has been printed, it will still be coated with excess liquid resin. Each Formlabs printer includes a finish kit designed to make part
cleaning simple and organized. Users remove models from the build platform and then wash parts in isopropyl alcohol for 20 minutes. Once
the part is dried, users can easily remove the part using the flush cutters and the print is ready for final use.

Dental SG Resin

An autoclavable, Class 1 biocompatible resin, Dental SG is designed for printing precise surgical guides and similar devices.

Resin Tank Wear and Dental SG Resin

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.

Tanks Are Consumables

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.


Standard Grey Resin

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.
