Top Ten FAQs

For a clean build plate, apply hairspray liberally and let dry for five minutes.  Reapply and let dry for another five minutes.  Then apply light coat and let dry for a minute or two.  You are ready!

You do not need to clean (water or otherwise) the build plate between prints.  For a "dirty" plate, simply flash/light coat of hairspray between prints.  If there is significant build up on the plate, then go ahead and wash it warm water.




  1. When the printer is first plugged in, the lights cycle to show the Polar3D logo fully lit up.

  2. Once the printer enters the boot cycle, the LEDs in the "3D" part of the logo are turned OFF.

  3. When the printer is searching for one of your preconfigured wireless networks the 3D turns RED. This might be for a split second or it may take several seconds.

  4. If the printer is able to successfully connect to your wireless router the 3D will turn YELLOW.  This means that it was able to connect to a wireless network but does not indicate you have successfully connected to the Polar Cloud.  If it stays YELLOW that means we can't talk to the cloud, so there might be an issue where the ports are being blocked by your network administrator.

  5. If the printer is able to connect to the cloud, the 3D turns WHITE, indicating the printer is ready to go.

  6. If a connection to your wireless router CANNOT be made (and no ethernet connection is available) the 3D will turn BLUE indicating the printer came up as an Access Point.  (the whole Polar3D logo on the printer is BLUE)

If the printer is out of date, an "Update" button will appear on the Summary page of the printer in the cloud. This occurs as long as you are on a version of the firmware newer than .28.

You can always force an update by typing in http://{localip}/update as well; where {localip} is your printer's IP address, which you can get from your router or from the "Go to local IP" button.


The advanced printer settings are currently only available in the cloud. When you load the object to the build plate, you should see a "Cura Settings" tab next to "Object Placement" on the right.

Multiple solutions depending on issue:

  1. Make sure serial number is registered in the system

  2. Make sure you printer is listed as a Polar 3D printer

  3. Update your firmware

  1. Start the printer up to where it starts as an access point.  (all lights blue)

  2. Connect to the printer's wifi hotspot and go to the printer page. ( http://192.168.0.1)

  3. Remove all known networks from the save network list.  (confirming the networks were properly removed)

  4. Unplug the printer and plug it back in.

  5. Reconnect to the printer's wifi hotspot and open up the printer's local web page again.

  6. Try to re-add your wifi network. (confirming it shows up on the list up top)

  7. Unplug the printer and plug it back in.

Apply a small drop of PTFE bike lube to the threaded rod, or other areas of the printer that are making a squeaking noise. (Tri-flon lubricant is what we use at Polar)

This issue commonly occurs when several printers are registered in the system as "Other" brand printers.  If you edit the printer settings and switch them to "Polar 3D" you can reenable that camera feed.

That also allows the system to capture last images as well as the time lapse feed that will show up in your printers print history.
