| + | 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 |
| + | ## Preform is the software we will use to import or model to the printer. |
| + | ## To begin with, make sure the print is under the approve cost/size cutoff ($7), or the person printing has special approval. |
| + | ## If a window pops up saying the print is broken, hit the repair button then proceed as normal. |
| + | ## Parts must be shrunk to fit within the build area, further size edits can be made in the Size tab. |

| + | 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 |
| + | * If a window pops up saying the print is broken, hit the repair button then proceed as normal |
| + | * Parts must be shrunk to fit within the build area, further size edits can be made in the Size tab |
| + | [[File:Size set.jpg|none|thumb|1045x1045px| Image 1-Model too big for build plate--Image 2-Model shrunk to fit build plate]] |
| + | * All prints should be slightly canted (angled) to prevent the delamination process from removing the print from the build plate |
| + | ** The goal is to reduce the horizontal area covered with each pass of the wiper |
| + | ** Start with auto-orienting the part using the 'Orient Selected' button in the Orientation tab, this is a good place to start and will make it easier to see if the part needs further orientation |
| + | * Don't place supports on hard edges (right angles) 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''' |
| + | *** Preform shouldn't let you print with unsupported areas |
| + | ** Supports can be added, edited, and removed in the PreForm Supports tab |
| + | *** Support density should be between .5 and .7 |
| + | *** Support point size should be between .6mm and .8mm |
| + | *** These values can be edited if necessary to ensure printability, just use common sense when adjusting values |
| + | ** Larger prints will require more support than smaller prints |
| + | * The Layout tab can be used to add additional copies of a part |
| + | * Ensure the proper printer and resin type are selected in Preform prior to starting the print |
