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

### 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.

### Even if you are certain your part belongs on the F370, double check with a lab volunteer before you add it to the pack. Their goal is to help you, but the Prototype Lab would like to avoid excessively expensive and/or unnecessary prints.

## GrabCAD Print is the software shared by the F370 and [[Dimension 3D Printer|Dimension]] printer. It allows one to easily orient and view the part that needs to be printed. Both printers are web based, which allows one to start the print from the one of the lab's computers. '''Give yourself a few days before your project is due to print on either F370.''' Prints will generally be started when a tray is full or at the end of a day by a lab volunteer, and unless there is little to be printed, it is unlikely your print will be started just because you waited until the last minute. Be proactive.

## On Opening GrabCAD, make sure that you navigate to the bottom right of the screen and select the menu next to "Print." Select the printer you want to use; in this case, the F370, which will appear as "f370D30365". The volunteers in the lab can help you determine which printer would work best.

## To begin preparing your part, click on "Add Models". This is how you import your file into GrabCAD.  '''Your file must be in .stl format.''' After you have added your part, you can begin preparing it to be printed. Multiple models can be added to the project. Additionally, models can be placed on new trays if the current one runs out of space.[[File:Icons.png|300x300px|none|thumb]]

## 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.

## Select "Print." The software will prepare the print. For larger trays, this may take several minutes, but usually takes around 30 seconds. If a print is currently ongoing, a bar across the top will read, "Print job queued successfully."

## Once your part has been prepared, you can click on on "View Estimates" in the bottom right-hand corner. You will see print time and the amount of model and support material that will be used, in cubic inches (in^3). This is an example of what the tray estimation page looks like. The model and support material used can be input into the Job Log in the lab.[[File:Estimate.png|none|thumb|300x300px]]

## Touchscreen operation on the F370 is highly intuitive. In the image below, the four icons on the left are as follows:

### Home - Displays the current tray to be printed. If a print is in progress, it will display how much time is left in the print and what is being printed. After a few minutes, a screen saver will switch between displaying which layer is being printed and how much time is left on the current print.

### Queue - Shows which trays are queued. This can also be viewed in GrabCAD.
