-  * The Form 2 is a 3D printer that uses SLA (stereolithography) to make a part. In SLA, a laser beam is directed into a tank of photoreactive resin, which hardens to form a layer of the part. The first layer adheres to the build platform, and each following layer adheres to the previous one. The finished part will be suspended upside-down above the resin tank. It has a build volume of 145 × 145 × 175 mm (5.7 × 5.7 × 6.9 in).

It has a build volume of 145 × 145 × 175 mm (5.7 × 5.7 × 6.9 in).
   * The Form Wash is an automated washer that bathes the printed part in IPA (isopropyl alcohol) to wash off residual resin.
   * The Form Cure is a chamber that exposes a printed part to UV light to finish the curing process. This is referred to as ‘post-curing.’

 More information on the resin system and changing a cartridge can be found on the webpage
 “Formlabs Resin Tank Information” through the Formlabs website.
+Both the resin cartridges and build platforms are cross compatible with both the Form 2/3 as well as the newer Form 3 3D printers however the build tanks are not interchangeable. Types of resins are distributed between the Form 2/3 and Form 3 based on frequency used as well as which benefit from the low force SLA process employed by the Form 3 and should not be swapped without consultation with the staff.
   - Remove the empty resin cartridge:

     * Never use IPA on the acrylic tank window (it will cause cracks).
     * If dust, fingerprints, and/or contamination are present, clean the clear acrylic tank window with NOVUS No. 1 and a clean microfiber cloth. The clear acrylic tank window is located on the underside of the resin tank. Apply 1-2 full sprays of NOVUS No. 1, and wipe using long, sweeping strokes top to bottom and across the tank window. Fold the microfiber cloth after each swipe to prevent dust and debris from scratching the acrylic.

-Contact: andrewfurst@ucsb.edu      \\
-====Safety Concern====
-  * Lab coat and gloves must me used when handling resin
-  * Anything with uncured resin must be transported within a container to avoid spilling
-====Safe Operation Procedures Review====
-  - Check resin cartridge and tank, make sure build material matches and is desired material.
-  - If resin is not desired material, disconnect wiper at build tank, remove build plate by sliding towards front of fume hood. Remove cartridge, cap valve on bottom and close valve on top of cartridge. Replace build tank, wiper, and cartridge with desired material.
-  - Launch Preform on Ultimaker computer
-  - Import desired STL
-  - Select "one click print" in the top left corner menu, change position, orientation, resolution and support as desired (note: that Preform will report on print ability of model, changing part rotation can affect print ability.
-  - Select print (orange button) from top left menu
-  - Select desired printer
-  - Press button on Formlabs printer to start print
-====Post Processing====
-  - Excess resin should be removed from the build tray and part with IPA over a waste container.
-  - Place build tray and part in the Form Wash for 20 to 30 minuets (part can be placed individually within basket if necessary
-  - Allow 30 minuets for IPA to evaporate before placing part in Form Cure
-  - Set Form Cure time and temperature based on resin type, place part within form cure, wait for time to elapse
-====Maintenance====
-  * Switching resin types
-    * Close breather valve on resin cartridge
-    * Remove the resin cartridge by pulling straight up on the handle behind the form labs printers
-    * Cap the cartridge valve using the included orange tap and cap
-    * Remove the wiper by pulling straight out towards the front of the fume hood.
-    * Pull the resin tray out of the printer by pulling firmly straight out toward you
-    * Lift the wiper and resin tray out simultaneously, and carefully place on resin shelf within fume hood.
-    * Cover resin tray with black plastic cover and label
-    * Replace resin tray with clean or desired resin tank. Push tank and wiper firmly back toward the Form 2 until it clicks into place
-    * Replace resin cartridge and open valve
