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!

The Extruder

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 in dimensions of 8" x 8" x 8". The only problem we had with the 3D printer was the extruder head of the printer was fairly difficult to load and change filaments due to the extruder case that connected the extruder to the guide-rods. We did print parts to attempt to fix this, but none of the printed parts fitted with the printer.

Ordering

After searching through the internet trying to find a good price on a printer, we finally settled on this 3D printer, which was purchased for just under $180. 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, that would definitely be worth the money.

Assembly

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

1. Step 1
2. Step 2

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.
