==The Extruder==
[[File:Extruder.jpg|thumb|"The Extruder"]]
The Extruder is a 3D printer that was built by Isaac VonShriltz, Keenan Jones, and Hayden Spitler.
It was built and programmed in Stallings's Computers II class, and is capable of printing in dimensions of 8" x 8" x 8".
===Ordering===
After searching through the internet trying to find a good price on a printer, we finally settled on [http://www.ebay.com/itm/like/252554605495?lpid=82&chn=ps&ul_noapp=true this] 3D printer, which was purchased for just under $180 shipped.
We decided to purchase this printer because it combined a larger dimension and scale size, with a nice printing quality, for an affordable price. I would highly recommend this printer to anyone interested in 3D printing as a fantastic beginner's printer, yet I would also recommend it to anyone who is interested in 3D printing as a cheap, and useful personal printer.
===Assembly===
When we received the printer, it came with instruction videos on the assembly of machinery.
The videos are

===Issues===
Hot end calibration: <code>M92 E105</code>
Measure 30mm, extrude, measure difference: [distance in mm] x [E steps per mm] = [steps per mm]
Take difference: [steps per mm] / [extruded] = [new steps per mm]

TSAS currently has three 3D printers: an Ender 3 Pro, an Elegoo Saturn and a Prusa i3 clone, the Anet A8. Technical information on our Ender 3 and Elegoo Saturn is coming soon, and info on the Anet A8 is here. We started printing with a PrintrBot Play, since retired.

Want Something Printed?

  1. Find some 3D Model Sources, or make one. Note that a print cannot take longer than a school day—this means you probably cannot print a mask or large statue.
  2. Email it to Stallings
  3. Objects created by another artist not used for class cost $1.00 per print if printed on the Ender or Anet, $2.00 per print if printed on the Saturn
  4. There is no charge to print original objects (those created by you) or those used for a class
  5. Be sure to share your designs and creations in the Gallery!

Printing Rules

  • You may not print objects subject to trademark or copyright law
  • No weapons, including blades or firearms (including non-working replicas) may be printed
  • No object that would violate the student code of conduct may be printed

How to Build a Model and 3D Print in 4 Steps

  1. Head to SketchUp on a Chromebook or SketchUp on the Desktop
  2. Build the 3D Printing Badge
  3. Slice the badge
  4. Print it!
