3D Printing

TSAS currently has two 3D printers, a Printrbot Play and a Prusa i3, refereed to its builders as The Extruder.

How to Print

1. Earn the 3D Printing Badge
2. Find a model, or make one. We can currently print up to 4" x 4" x 5" models.
3. Download Cura, an open-source slicing program for 3D printers.
4. Download the PrinterBot settings file here, and load it into Cura.
5. Check your file for errors and make sure it fits!
6. Fill out this form and email the file to the printer.
7. Watch it print!
8. Be sure to share your designs and creations in the Gallery!

Printing Rules

1. You may not print objects subject to trademark or copyright law.
2. There is no charge to print original objects (those created by you) or those used for class.
3. Objects created by another artist not used for class cost $1.00 per hour of printing time.
4. No weapons, including blades or firearms (including non-working replicas) may be printed.
5. No object that would violate the student code of conduct may be printed.

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 Computers II class, and is capable of printing 8" x 8" x 8" The Extruder has had a few upgrades installed onto it, all of which have been 3D printed. Most of the upgrades on the printer have ironically related to the extruder head of the printer.

Ordering

After searching through the internet trying to find a good price on a printer, we finally settled on the 3D printer was purchased for just under $180 at http://www.ebay.com/itm/like/252554605495?lpid=82&chn=ps&ul_noapp=true We decided to purchase this printer because it combined a larger dimension and scale size, with a nice printing quality, for anafordable price.

Assembly

When we received the printer, it came with instruction videos on the assembly of machinery. The videos are

1. Pre Test:
2. Step 1
3. Step 2

The printer also came with a De-bugging video.

1. A8 De-Bugging Video:

One of the problems that we encountered while building the printer was the calibration and setting of the Y-axis. The system automatically calibrates itself when beginning a print, and can have a calibration set up manually as well. The way we were able to fix the calibration issue was by placing a piece of paper underneath the extruder head, and slowly dropping it until it was almost putting pressure on the paper, and when the paper is able to freely move, with the extruder head as close as possible, remove the paper and set the calibration bumber on the Y-axis to be pressed as far up as possible to the guide-rod and re-calibrate the system.

Another installment we put on the printer was a different 3D printed extruder case. The original extruder head worked, but made it slightly difficult to load filament. To solve this, a new casing was printed that would allow for easier loading of filament.
