# Setting up PreForm

 

## PreForm is the software we will use to import or model to the printer.  When connecting to PreForm you need to make sure the wifi is enabled and connected to bruin Secure. Make sure the correct printer is selected as well.

#Setting up PreForm

## To begin with, make sure the print is under the approved cost/size cutoff ($7), or the person printing has special approval to exceed this limit.

## 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.

##If a window pops up saying the print is broken, hit the repair button then proceed as normal.

### 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.[[File:Size set.jpg|none|thumb| Image 1-Model too big for build plate--Image 2-Model shrunk to fit build plate]]

##Parts must be shrunk to fit within the build area, further size edits can be made in the Size tab.

## Don't place supports on hard edges (right angles) or in inaccessible places. This will cause the print to be unprintable.

## 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 because PreForm will not let you print with unsupported areas.'''

## Ensure you are connected to Bruin Secure wifi with the proper printer and resin type selected in Preform prior to printing. Additionally, make sure that the resin you want is already installed in the printers. If the resin needs to be changed to the one that you want, ask a Lab Volunteer to help you.

## You will be able to start your print using the touchscreen on the Form 2. If it is sleeping, just press the button and it should wake up.

#Operating the Touchscreen

##You will be able to start your print using the touchscreen on the Form 2. If it is sleeping, just press the button and it should wake up.

## There are two other buttons you can press on the left screen. The USB button will take you to the settings of the printer, so you will not need to go here. The checklist button brings a list of every job that has been uploaded to the printer, so you will want to be selecting this one to find your print. When you find your print, select "print now". The printer will make sure that you perform the appropriate setup before it starts printing, such as inserting the tank in the back of the printer and assuring that the build plate is cleared of other printed parts.

### Follow the same process for finished prints for removing.

##Failed prints

### '''When a print fails, the build plate must be cleaned and run through the Wash''' before a new print can be started, as leftover residue from the failed print can cause subsequent prints to also fail. You will also need to check the resin tank for clumps as well as double check the model orientation.  Don't forget to update the job log as well.

# Dredging: Every few prints the resin tank should be checked and dredged with a scraping tool to search for any hardened resin or loose bits of material, as well as 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 tank is not cleanable, switch out the resin tank. If the problem persists, it's possible the resin cartridge needs to be switched out as well.

 

# Alcohol in the Form Wash must be changed once a certain threshold of washed-off resin enters the tank. See the [[Form Wash and Cure]] page for details.
