3D Printers

From Help Wiki


  • The 3D printers are set up in the Physical Computing Center, Library building 2708.
  • On the second floor on the Library building make a left at the entrance to the library, down the hall and across from Media Loan.


Makerbot Replicator 2

  • There is one Makerbot Replicator 2 printer in the room.
    • Use the Makerbot software to export your model as an X3G for the Replicator 2
    • Transfer your files onto the printer with the SD cards.

Lulzbot Mini

  • There is one Lulzbot Mini.
  • Connect to it with the Cura application on the computer in the room with a USB cable.


  • Use only Cura with the Lulzbot; make sure it's configured for the Lulzbot Mini.
  • The Makerbot software is installed if you need to convert files.
  • There is a memory card reader for loading files on to SD cards.


  • If you leave the area while printing make sure to close the door.
    • Do not leave for more than 15 minutes. The printers can jam and stop printing.
  • You'll need to copy the X3G file to the SD card. There is a computer with an memory card reader in the room.
  • Make sure that there is enough filament on the spool and that it feeds freely.
  • Don't make the filament very loose on the spool--it can tangle and bind up
  • Use the key pad to choose "Build from SD". find the file and print.
  • The printer will heat the extruder, draw an initial line and start the print
Problems to Watch for
  • Watch the first two layers closely to make sure that they stick to the bed.
  • If the first layer fails, cancel the print, clear the bed and try again.
  • Watch for print not sticking to the bed.
  • Watch and listen for the feed stopping. This often makes a repeating clicking sound and no plastic coming out of the nozzle.
  • Continuously check that the filament is feeding off of the spool.

If Things Go Wrong
  • Do not try to do repairs or maintenance on the printers.
