3D Printers

 

We have several 3D printers: a Lulzbot Mini, Lulzbot TAZ6, and a Gigabot. The Lulzbots are connected to a 3DPrinterOS server, which allows for remote access. Both printers have PrintBite surfaces on the beds, and therefore do NOT need a glue stick, blue tape, etc. to adhere. These adhesives can damage the beds, please do not use them.


Lulzbot TAZ6


Lulzbot Mini

 

Method 1 (3dprinteros.com):

This method is the simplest and most convenient. It currently does not support the Gigabot printer.

  1. Visit https://www.3dprinteros.com/ and login using the credential found printed on the sign at the printers.
  2. Upload your .stl file to 3dprinteros
  3. Next to your file, click on Apps > STL Editor
  4. Once the editor is open, choose the printer you want to use and layout your part on the print bed
  5. Click the Save & Slice icon
  6. In the Slicing dialog box, select the profile that most closely matches your filament type
  7. Click Slice
  8. A new .gcode file will be created, click the Print icon associated with this file

 

Method 2 (Cura):

This method works for all printers.

  1. Start Cura by clicking Applications > Graphics > Cura
  2. File > Open Profile and select the profile most similar to what you'd like to print. The profiles can be found on the Lulzbot website, and here for the Gigabot.
  3. Configure the print as needed
  4. Save gcode to an sdcard
  5. Load the sdcard into the Gigabot or Taz6, and use the printer's LCD interface to select your .gcode file for printing

Filament

The Lulzbots and Gigabot use 2.85 or 3mm filament. Loading Filament

  1. Select the filament you would like to load
  2. In Octoprint, manually set the nozzle temperature to the melting point of the filament currently loaded in the printer.
  3. Undo the latch in the extruder, and remove the filament in the printer.
  4. To load new filament, cut off a small amount of filament at about a 45 degree angle to assist in loading
  5. Guide the filament into the extruder until it extrudes out the hot nozzle. Re-latch the extruder bearing.

 

Troubleshooting

 

  • If the bed of either printer appears dirty, the best practice to clean it is with the Isopropyl alcohol located next to the print tower. Use only a clean paper towel or scotch pad when necessary
  • To remove a stuck print, best practice is to heat the bed to about 50C to loosen the printed part, then the part should come off with relative ease.
  • If your print is not sticking to the bed, do NOT use a glue stick, blue tape, or other adhesives as advised by the internet. Our PrintBite bed surfaces will be damaged with these tactics. Instead, find the correct temperature and orientation for your print and it will adhere well.
