-  * 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).
+  * The Form 2/3 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.

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.’

   * Care must be taken to prevent contaminating other areas with liquid resin - use containers to transport build platforms or parts that still have liquid resin on them.

 “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:
     - Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed
-    - Hold the cartridge handle and lift to remove from the Form 2. Store the cartridge upright with the valve cover installed to protect storage surfaces from resin.
+    - Hold the cartridge handle and lift to remove from the Form 2/3. Store the cartridge upright with the valve cover installed to protect storage surfaces from resin.
   - Insert a new resin cartridge:
     - Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly.
     - Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer.
     - Press open the vent cap to ensure the resin tank can fill correctly
+**New build tanks should be marked off when a new resin cartridge is put into rotation. This allows us to keep track of the wear on the build tanks and troubleshoot the printers more easily. Each new build tank is marked with a countdown of the number of liters remaining. Continue to numbers off the list as new resin tanks are put into use.**

+====Maintenance====
+  * Cleaning resin tank interior
+    * Use the scraper from the finish kit to inspect the resin and the elastic layer. Starting from the top corner, gently scrape from top to bottom across the elastic layer.
+    * Check for the following issues that may lead to print failures or any excessive wear that requires replacing the tank:
+      * cured resin on the elastic layer
+      * debris or failed prints in the resin
+      * settled pigment on the elastic layer
+      * punctures, cuts, or gouges in the elastic layer
+      * excessive “clouding” or wear in the elastic layer
+  * Filtering Resin
+    *  Use a filter to remove any debris or small bits of cured resin floating in the tank. Clean, debris-free resin helps avoid print failures, which may damage the tank.
+  * Cleaning the tank window
+    * 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.
