The BIO X won’t recognize my STL.

  • Make sure the USB flash drive is inserted firmly into the USB port.
  • The BIO X currently supports binary STLs and not ASCII STL files. Many CAD software suites export ASCII STLs without providing an option. Download Heartware, open your STL and click the export button.

Nothing is extruding.

  • Working with a nozzle and cartridge that has gone through many uses can sometimes result in your nozzle clogging, preventing you from printing. Please exchange the nozzle and try your print again.
  • Check to see if air pressure is extruding by selecting “test bioink flow” without a cartridge attach to the printhead. Place a finger over the pneumatic outlet to see if any air is coming out.
  • If you are still experiencing issues, contact support.
