Changing the material and nozzle

Changing material

Materials can be changed easily on the Ultimaker 2+ by using the procedure from the menu.

1. Go to the menu Material > Change.
2. Wait for the nozzle to heat up and reverse the material.
3. Remove the material from the feeder and spool holder.
4. Place the new material spool on the spool holder. Make sure to put it with the material in counter-clockwise direction, so that the material can enter the feeder from the bottom.
5. Insert the material into the feeder and push it until the feeder grabs it and the material is visible in the Bowden tube. Confirm to continue.

   Note: Straighten the end of the material a bit so it can easily enter the feeder.

6. Confirm when the new material extrudes from the nozzle.

Changing the nozzle

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) and tools to change the nozzle. The 0.4 mm nozzle is already installed on the Ultimaker 2+.

Removing the current nozzle

1. Go to Material > Change to remove the material from the Ultimaker 2+.
2. Clean the nozzle by performing the Atomic Method.

   Note: 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.

3. Leave the temperature set to the last temperature that was used for pulling out the filament during the Atomic Method.
4. Use the wrench to unscrew the nozzle from the heater block. To unscrew it, you have to turn it counter-clockwise.

   Caution: Be careful, the nozzle is hot.

Installing the new nozzle

1. Select the desired nozzle and screw it manually into the heater block until hand-tight.

   Caution: Be careful, the heater block is still warm.

2. Use the wrench to tighten the nozzle completely. Turn it clockwise and do not use too much force to avoid damage.

Setting up in Cura

Before being able to print with the newly installed nozzle, the setting in Cura needs to be changed. Select the correct nozzle size from the list in Cura, next to Nozzle & Material.
