How to utilize the Lee Library's 3D printer. Includes direction on obtaining or designing files for print and the procedures for preparing and sending for print.

What Is 3D Printing?

A 3D printer takes a 3D drawing rendered on a computer and extrudes a plastic filament to "print" the object.  The Experiential Help Desk has two 3D printers and one resin printer available for patron use so that you can make your creations a reality.

First, you will need a 3D drawing to print out.  You can create your own or find free designs available online. To ensure that your finished print will be what you expected, make sure to run your file through a print preparation program.

Second, bring the drawing exported as an .stl file on a flash drive to the Science & Engineering Help Desk, or email it to Then, stop by the desk and we will help prepare the print by asking questions about preferences in regards to dimensions, infill, supports, raft, etc. 

Finally, after the object is finished printing, you will want to give it some finishing touches.  You might remove support material, use sandpaper to smooth it out, or add some paint to give it the final appearance you want.
