=== Why Pick the Form 2? ===
=== Why Pick the Form 2? ===
The Form 2 is most useful for its ability to print incredibly accurate parts, with layers as thin as .025mm thick, depending on the resin selected. Due to the size of the Form 2, it can only be used to print smaller pieces, and the extra layering for detail combined with the de-lamination process also causes the Form 2 to generally be the slowest printer in the lab. Unless an exception is made, a model with supports included should be no larger than 30mL worth of resin. If specific material properties are needed for a print, the Form 2 is a good option to look into thanks to the many differing resins available for use.

=== Setting up Preform ===
Follow the Code: a few guidelines should be observed when setting up prints:
* To begin with, make sure the print is under the approve cost/size cutoff, or the person printing has special approval
* All prints should be slightly canted (angled) to prevent the delamination process from removing the print from the build plate
* Don't place supports on hard edges or in inaccessible places
* Supports should be used in accordance with the part
** Every part that needs support should have support - PreForm will highlight unsupported areas in red, place supports until the red areas go away, '''check the part thoroughly'''
** Supports can be added, edited, and removed in the PreForm Supports tab
** Larger prints will require more support than larger prints

=== Common Errors ===
If a print fails, the most likely cause is contamination of the resin. Before proceeding, see the procedure for Failed Prints. Contamination of the resin involves leftover material on the build plate, or particulates in the resin tank. Before attempting a new print, thoroughly clean the build plate, and dredge the resin tank for any loose particles. Another cause is incorrect orientation of the print. Check the print file in question, and ensure it has been canted accordingly to prevent the de-laminating process from removing the print from the build plate.

* Every few prints the resin tank should be dredged with a scraping tool to search for any hardened resin or loose bits of material, when resin tanks are switched out, and when a print fails. Remove any found bits. Dredging is done by sweeping a scraping tool back and forth across the bottom of the resin tank, essentially mixing up the resin to stir up any loose bits. Take care while dredging to not scrape the tank. See a resin's particular page on the Formlabs website for additional cleaning instruction.

If the problem persists, it's possible the resin cartridge needs to be switched out as well.
