The basic workflow for using the F370 will be as follows: Preparing the Printer, Preparing Your File for Print, Printing Your Part, Soaking Your Part. First, you prepare the printer so that it is physically ready to print any design you give it. Second, you prepare the part on the software used by the F370. This generates a file to that tells the machine how to produce your part. Third, the machine prints your part. Fourth, you soak the part in the bath so that it dissolves all the support material. Then you have a finished part! Each section below will have specific information relevant to each step. You are encouraged to speak with a lab volunteer for advice and guidance for any step of the process.

## Powering on the Printer
## Powering on the Printer
### The F370 can be powered on by pressing the large power button next to the touch screen console on the front of the printer. The printer may take up to 15 minutes to boot up, so do this step first if you plan to print soon.

## Before you can open your part in GrabCAD, make sure your part is in the '''.'''STL format.

## Acceptable Prints
## Acceptable Prints
### The maximum part size is 14 x 10 x 14 inches, or 35.56 x 25.4 x 35.56 centimeters, because that is how large the build plate is. Any part that large should be shown to a lab volunteer to discuss options.

### Generally, a part will be fit for the F370 if it is highly detailed and/or has holes that require fairly high tolerances. If it is a small, detailed part, a Form 2 printer should suffice. If the part is quick and simple, a Prusa will likely suffice.

### If your part is designed to take advantage of the dissolving support material the Stratasys machines use, then verify with a lab volunteer that it will be okay to print.

## '''You MUST print your part with "Sparse - low density" fill.''' It is expensive to print with Stratasys materials, thus you must consult a lab volunteer if you have a part you feel needs a denser fill. All of standard settings generally do not need to be changed.[[File:Density.png|thumb|none|300x300px]]

## After your part has been prepared, save the project before continuing. Generally, you will not start the print in the lab itself, since a volunteer will start it when a tray is full or when the day ends, but the workflow is as follows.

# When you are removing the support material by hand, it can be a little hot and sharp to begin with. Using a tool of some sort to chip it off is a good way to go, because hands bleed and tools don't :)

# When using the dissolvable support bath is used, do not use your bare hands to put your parts in! it is Sodium Hydroxide which is toxic! Use goggles, a lab coat, and the huge thick rubber gloves so that you don't get any on you.

# Changing Materials (Loading Filament Spools)
# Changing Materials (Loading Filament Spools)
## Only volunteers will change out materials. If the F370 runs out of filament or you would like to use a different color, please speak to a lab volunteer.

## There are four material bays within the F370. The top drawer houses the material bays and their material drive controller, which feeds the filament from the bay to the head. '''The material drive controller detects whether material within the material drive within the material drive during the load and unload process and can also detect errors, when filament is broken, or when the end of the spool is reached via a filament present switch. [''This sentence needs to be revised by someone that understands the details of the "material drive]''''' The print will be paused if any of these things occur so the print can be recovered and filament reloaded.
