What Do My Bioprinter’s Lights Mean?

Stage Lights

Allevi 1 and Allevi 3 bioprinters come with a bright stage light for improved viewing, but different colors can also indicate the status of your bioprinter and help you troubleshoot various issues. So what exactly do your bioprinter’s lights mean? Here’s everything you need to know!

Yellow

  • If you just powered on your bioprinter, yellow lights indicate it is currently booting up. These lights should turn off after 30-60 seconds.
  • Yellow lights can also indicate a software update. Depending on Internet speed, this could take up to 30 minutes.
  • Pausing a print will turn on yellow stage lights. They will turn off after you resume the print.
  • If an error caused your printer to crash, the lights will turn on. Powercycle your bioprinter to start again and contact the Allevi Support Team.

Orange

  • Your bioprinter is autocalibrating. The lights will turn off once it is done.
  • If the orange light doesn’t turn off, check if the light around the power button is flashing.
    • An orange stage light with a flashing orange light around the power button indicate an autocalibration time out.
    • Try repeating autocalibration. If that doesn’t work, refer to the ‘Autocalibration started but it never finished and the printer appears frozen‘ section of the troubleshooting steps here.

Red

  • Your bioprinter was set to a pressure higher than the supplied pressure from the air compressor. Your bioprinter will stop trying to reach that set pressure.
    • Increase your air compressor’s supply pressure and try again.
    • Turn your stage light on and off to remove the red warning light.

Blue

  • Your Allevi 3 is undergoing a calibration of the extruder track system. This process should only occur after entering a specific command during troubleshooting.

Power Button

The power button is useful for indicating safety checks, specifically for autocalibration. When present, the LEDs will flash a certain color. This is not available on all printers.

Steady Red

  • The printer is receiving power.

Flashing Blue

  • The print head did not fully extend.
  • The print head did not fully retract.

Flashing Red

  • The bed plate cannot or did not descend to home position.

Flashing Orange

  • It took too long for your needle to touch the sensor and autocalibration timed out.
  • The touch screen is disconnected.

Flashing Green

  • The printer is undergoing a factory reset.

NOTE: To reset the light, toggle the stage light in your software.
