How does it work?
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.
KEY PARTS OF THE PRINTER
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.
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.
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.
Automate cleaning with Form Wash
- Automated cleaning of parts straight out of the printer.
- Consistently Clean: Form Wash’s rotating impeller agitates isopropyl alcohol (IPA) around every nook and cranny of your parts, getting them perfectly clean–every time.
- Built to Fit the Build Platform: Parts travel straight from the Form 2 to Form Wash; they can stay right on the build platform or be placed in the basket.
- Automated Wash Cycle: Manual washing requires careful attention, as parts left too long in IPA can become warped/deformed. Form Wash automatically raises parts out of IPA when wash time is up. Parts air dry and are ready when you are.
- IPA Calibration: Form Wash can hold up to 8.6 L liters of IPA, enough to wash approximately 70 prints. The hydrometer lets you know when it’s time to change out IPA. A siphon makes it easy to transfer IPA in and out of the wash bucket.
Form Cure is finely tuned to bring parts to their maximum mechanical properties.
- Maximum mechanical properties for high-performance materials.
- Advanced Heating: Heat control is the key to precise, successful post-curing, carefully scaling temperatures up to 80 °C in the cure chamber.
- Balanced Light: 13 LEDs use 405 nm Light to trigger the post-curing reaction, working with the heater to post-cure parts.
- Uniform Exposure: A rotating turntable, heat flow, and dispersed lights provide uniform exposure during post-curing.
- An Intuitive Interface: It’s easy to set Form Cure’s temperature and post-cure time. For Standard Resins, simply use the default. For all other materials, use recommended settings for optimum performance.
