A Nozzle Kit is supplied with the Ultimaker 2+. This kit contains three nozzle sizes (0.25 mm, 0.6 mm and 0.8 mm).
The 0.4 mm nozzle is already installed on the Ultimaker 2+.
To replace the nozzle:
REMOVING THE CURRENT NOZZLE
1. Remove the filament from the Ultimaker 2+ (via the “Material” > “Change” menu). See “LOADING AND CHANGING
FILAMENT” on page 22.
2. Perform the Atomic Method before removing the currently installed nozzle. This minimizes the amount of leftover
plastic that is locking down the nozzle and makes removal easier. It also cleans out that nozzle prior to storage,
ensuring that no filament residue remains in the nozzle that may affect future prints. See “ATOMIC METHOD” on
page 31.
3. Leave the temperature set to the last temperature that was used for pulling out the filament during the Atomic
Method. (e.g. 90 degrees Celcius for PLA).
4. Use the wrench to unscrew the nozzle from the heater block. To unscrew it, you have to turn it counter-clockwise.
INSTALLING A NEW NOZZLE
1. Select the desired nozzle and screw it manually into the heater block until hand-tight. Be careful, the heater block is
still warm.
2. Use the wrench to tighten the nozzle completely. Turn it clockwise and don’t use too much force (if you tighten it
too much, it can break).
