Start a print on the Ultimaker 3

Use Ultimaker Cura, Ultimaker's free print preparation and management software, to prepare your 3D digital object for printing on your Ultimaker 3. You can download Ultimaker Cura here.

Tip: For best printing results, always use the latest version of Ultimaker Cura. For more information about using Ultimaker Cura and system requirements, please see the Cura section of the support pages.

The Ultimaker 3 supports:

  • Printing via cloud
  • Printing over local network
  • Printing via USB

Printing via cloud

The Ultimaker 3 can benefit from several features available via the cloud. To make the most out of the Ultimaker 3, associate the printer with your Ultimaker account and add it to your printer console on the Ultimaker Digital Factory. Learn how to connect your Ultimaker 3 to Ultimaker Digital Factory here.

Prepare your print in Ultimaker Cura and ensure you are logged in to your account. When you are satisfied with the print settings and preview, select Print via cloud in the action panel.

Printing over local network

Ultimaker Cura can send print jobs directly to the Ultimaker 3 connected on the same network. Add the printer via network in Ultimaker Cura and prepare your print. After slicing, click Print over network in the action panel.

Printing via USB

If your Ultimaker 3 is not connected to the network, use the USB workflow to start a print. Prepare your print in Ultimaker Cura. After slicing, you can save the file (gcode) directly to a USB drive, or save it to your disk for later. 

Tip: Ensure to always safely eject the USB device to prevent corrupting print files.

Insert the USB device into the port at the front of the Ultimaker 3. In the main menu, select Print and then select the print job from the list on the display.

Tip: The most recently saved print job will always be displayed first in the list.


Before you start your print, always make sure that the configuration chosen in Ultimaker Cura matches the print cores and materials installed on the printer. The information about the selected print cores and materials is included in the code file, so the printer will warn you if there is a configuration mismatch. The printer will instruct you which material(s) or print core(s) should be changed before you can successfully start the print.

Tip: If the printer is connected to Ultimaker Cura via local network or Digital Factory, the printer's configuration will automatically be displayed in Ultimaker Cura for an easier workflow.
