The Ultimaker 2+ Connect and Air Manager must be positioned out of direct sunlight when in use. Ensure there is at least 10 cm of free space at the back of the Air Manager for unrestricted airflow

First setup

After installing the hardware accessories, set up the printer for first use. Turn on the printer with the power switch at the back. After booting up, you will see the home screen. This displays your printer status, and allows you to quickly navigate to the Materials, Settings or Maintenance menus.

It is possible that the Ultimaker 2+ Connect shows a firmware upgrade screen when it boots up for the first time. If this is the case, go to ultimaker.com/firmware, select the Ultimaker 2+ Connect, and download the firmware file. Save this file to the root directory of a USB stick. While the device is powered on, insert the USB stick to automatically start the firmware update.

Level the build plate

To get the correct distance between the build plate and the nozzle, you need to level the build plate. The Ultimaker 2+ Connect utilizes a three-point bed level procedure. This must be done before using the Ultimaker 2+ Connect for the first time and then  periodically.

 Select the Maintenance menu and navigate to Level build plate. Follow the instructions on the display.

If you have installed the Air Manager, remove the front enclosure until this procedure is finished.

  1. Wait for the Ultimaker 2+ Connect to move the print head and build plate to the start position
  2. Place the calibration card between the nozzle and build plate. Adjust the thumb wheel under the build plate at the back until you feel some resistance when moving the card. Select Done adjusting to continue

The print head will move to the next position. Keep hands clear of the build volume until the print head and build plate have stopped moving.

Do not apply force to the build plate while placing the calibration card, as this will lead to leveling inaccuracies.

  • Place the calibration card under the nozzle again and adjust the front-right thumb wheel until you feel some

resistance on the card. Select Done adjusting to  continue

  • Repeat this for the front-left thumb wheel
  • As a final step, the printhead will return to the first point. Fine-tune the leveling, and check if you still feel the

same resistance on the calibration card at the back of the build plate, or adjust the thumb wheel until you do

The build plate is now leveled correctly for an optimal adhesion of the first layer.

Material compatibility

The Ultimaker 2+ Connect supports all Ultimaker build materials that are currently available, of which most can be printed with the 0.25, 0.4, 0.6, and 0.8 mm nozzle sizes.

All Ultimaker materials have been extensively tested and have optimized profiles in Ultimaker Cura to ensure the best print results. Therefore, it is advised to use one of the default profiles in Ultimaker Cura for the highest reliability.

Print recommendations

Each material requires different settings for optimal results. When using Ultimaker Cura to prepare your model,

these settings are automatically set correctly if the correct nozzle size and material are selected.

It is recommended to apply a thin layer of glue (using the glue stick from the accessory box) or an adhesion sheet to the glass build plate before starting a print. This will ensure that your print adheres reliably to the build plate, and also prevents the glass build plate from chipping when removing prints.

Chipped pieces of the glass plate stuck to the print after removing can cause cuts. Always use the recommended adhesion method.

The warning icon on the glass plate should face upwards. This side is best for printing and ensures optimal adhesion

For detailed instructions on which settings and adhesion method to use per material, take a look at the material manuals and adhesion recommendations on the Ultimaker website.3D printing thermoplastics may result in the release of ultrafine particles (UFPs) and volatile organic compounds (VOCs) depending on the filaments used and settings of the 3D printer. In case UFP emissions are unknown or are likely to be significant, it is advised to use the Air Manager with the Ultimaker 2+ Connect or use the printer in a well-ventilated room. Ensure that the filaments are printed at the advised temperatures; too high printing temperatures will cause additional emissions. Other measures needed to further control emissions strongly depend on the specific conditions under which the printer(s) are used

Preparing a print with Ultimaker Cura


After adding the Ultimaker 2+ Connect in Ultimaker Cura, the main interface will become visible. Here is an overview of the user interface (UI).

UI elements:

  1. Open file
  2. Printer selection panel
  3. Stages
  4. Configuration panel
  5. Print settings panel
  6. Action panel
  7. 3D viewer
  8. Camera position tool
  9. Adjustment tools

The Ultimaker Cura workflow is arranged in three stages, seen at the top of the interface. These are the prepare,

preview, and monitor stages.

Prepare stage

Load a model and prepare it for slicing in the prepare stage of Ultimaker Cura.

  1. Load the model(s) by clicking the ‘open file’ folder icon
  2. In the configuration panel, select the material type you wish to print with
  3. Use the adjustment tools to position, scale, and rotate the model as desired

The adjustment tools are visible when a model is loaded and selected on the 3D viewer.

  • Select your desired settings (profile, layer height, infill, support and build plate adhesion) in the

print settings panel

  • When satisfied with your print settings and print strategy, press the Slice button on the action panel
  • When slicing is complete, the action panel will now direct you to the preview stage

For more information about the prepare stage and the available settings in the custom menu, see the Ultimaker Cura support pages.

Preview stage

The preview stage allows you to see exactly how your model will be printed. Use the different color schemes to get various information about your model. You can view the different line types, differentiate infill from skin, or use the X-ray view to detect gaps within your model.

When satisfied with your model print preview, the action panel guides you to print over the network if connected to

a networked Ultimaker 2+ Connect.

Alternatively, you can save the file to a USB for printing with offline  printers.

For more information on the preview stage, see the Ultimaker Cura support pages found on the Ultimaker website.

Monitor stage

The monitor stage utilizes the Ultimaker Digital Factory functionality so you can easily monitor the status of your networked Ultimaker printer.

When printing on a networked Ultimaker printer, you can send your print jobs from Ultimaker Cura to the printer via the cloud. The status of the printer will change to Printing, and you can begin to track the print’s progress. You can also queue multiple print jobs and view them in the print queue.

Printing with the Air Manager

The optional Ultimaker 2+ Connect Air Manager is designed to simply and effectively increase user safety. The Air Manager consists of the top cover, filter, and front enclosure. Proper use of the Air Manager minimizes the emission hazards related to UFPs caused by 3D printing materials.

The Air Manager is highly recommended in classrooms, when printing with materials that emit significant

amounts of UFPs, or in locations with multiple 3D printers.

With a connected Air Manager, the Ultimaker 2+ Connect is enhanced with the following  features:

  • UFP filtering. The Air Manager encloses the top and front of the Ultimaker 2+ Connect and ensures an inside- out airflow. The air passes through an E10 filter whereby ultrafine particles (UFPs) get trapped
    • Physical barrier. The enclosed top and front prevent users from reaching into the machine during operation

and ensures particles from the environment do not influence the print result

The Air Manager will only work properly if all components are installed correctly. Ensure there are no gaps between the filter housing, cover, and the printer. The front enclosure must be installed when the Air Manager fan is running. Ensure that the Air Manager cable is securely connected and the fan is spinning during a print.

When a print has finished, wait until the printer has completely cooled down. This will allow sufficient time to filter all particles from the printing process. Then remove the front enclosure so you can take the finished print from the build plate.

When removing the front enclosure from the Ultimaker 2+ Connect, it can be placed on top of the Air Manager.

The shape of the front of the Air Manager cover aligns with the hinge profile of the front   enclosure.

Remove the print

Once your 3D print is finished it must be removed from the build plate. There are several methods to do this.

When using a brim, be aware of the danger of cutting yourself when removing the print from the build plate. Use a deburring tool to remove the brim once the print is taken from the build plate.

Always use the recommended adhesion method. Printing directly on the glass with certain materials can cause the build plate to chip. Chipped pieces of the glass plate stuck to the print after removing can cause cuts.

Wait for cooldown

If you printed directly onto the build plate, simply allow the build plate and the print to cool down after printing. The material will contract as it cools, allowing you to easily remove the print from the build plate.

The heated bed can reach temperatures of over 100 ºC. Do not remove the print or the glass build plate from the printer until the printer has cooled down. The display of the Ultimaker 2+ Connect will indicate when it is safe to remove the print or build plate.

Use a spatula

If your print is still adhered to the build plate after cooling, you can use a spatula to remove the print.

Use a spatula with rounded corners to avoid cutting yourself on sharp edges.

Place the spatula under the print, parallel to the build plate, and apply a small amount of force to remove the print. A spatula can also be used to carefully remove remaining parts of the print from the build plate, such as the brim or support structures.

Take the build plate out of the printer to avoid damaging the build plate clamps.

Use water

Remove the build plate from the printer when the display indicates it is safe to do so. Run cool tap water over  the

bottom of the plate to cool it quickly. Due to the contraction of the material, the print will easily pop off the plate.

Alternatively, you can run lukewarm water over the print side of the plate to dissolve the glue.

Confirm removal

Once the print has been removed and the build plate is placed back in the printer, confirm the print removal on the

display of the Ultimaker 2+ Connect. This will allow the next print job to start.

If the Ultimaker 2+ Connect is connected to the network and utilizing the Digital Factory, queued print jobs can start remotely. To prevent damage to the printer, do not confirm the print is removed until the build plate is clear and placed back in the printer.

If necessary, clean the glass build plate and apply a new layer of glue before starting the next print.

Change the printer configuration

Change material

Materials can be changed easily on the Ultimaker 2+ Connect.

 Select the Materials menu and navigate to Change material. Follow the instructions on the display.

  1. Select the new material type. If you want to load a new spool of the same material, select Yes. If you are

changing to a different material, select No and choose the new material type on the next screen

  • Wait for the nozzle to heat up
  • Open the feeder lever, pull the material out through the Bowden tube, and remove the spool

from the spool holder

  • Place the new spool on the spool holder with the material in counterclockwise direction Straighten the end of the material so it can easily enter the feeder.
  • Insert the filament into the feeder and push it through to the print head
  • Close the feeder lever
  • Confirm that the spool is loaded and wait for the material to extrude from the nozzle
  • Confirm and wait for the nozzle to cool down after this procedure

Change the nozzle

The Ultimaker 2+ Connect has a heater block with easily swappable nozzles. A 0.4 mm nozzle is already installed, and an extra 0.4 mm nozzle is included in the accessory box. Other compatible nozzle sizes include 0.25 mm, 0.6 mm, and 0.8 mm and can be purchased separately. To change the nozzle, use the 7 mm wrench that is included in the accessory box.

Before removing the nozzle, perform a cold pull to remove material residue from the inside of the nozzle.

  1. Remove the material from the print head

The filament only has to be partially unloaded, until it is visible above the print head. Use the Change material

procedure or raise the nozzle temperature via the Maintenance menu and unload the filament manually.

  • Place the print head in the middle of the gantry for easy access
  • Set the nozzle temperature to 100 ºC
  • Use the 7 mm wrench to unscrew the nozzle from the heater block, in a clockwise direction

The nozzle is warm. Take proper measures to catch the nozzle when it is loosened from the heater block. Protective (thermal) gloves are advised.

  • Select the desired nozzle and manually screw it into the heater block until it is hand-tight

Be careful, as the heater block is still warm. Protective (thermal) gloves are advised.

  • Use the wrench to fully tighten the nozzle

If a different size nozzle was installed, ensure to select the corresponding nozzle size in Ultimaker Cura to

prepare the next print job.


Update the firmware

Periodically, a new version of the Ultimaker 2+ Connect firmware is released. To ensure that your Ultimaker 2+ Connect is equipped with the latest features, it is recommended to keep the firmware updated to the latest version.

Update over the network

If the Ultimaker 2+ Connect is connected to a network, it automatically checks for available firmware updates. When a new firmware is available, the printer will prompt you to download and install it via the touchscreen interface.

Alternatively, check for updates manually by navigating to Settings Update   firmware.

Do not power off the printer during the firmware installation.

Update using a USB stick

If your Ultimaker 2+ Connect is not connected to a network, you can update to the latest firmware via USB. The firmware files are found on the Ultimaker  website:

  1. Navigate to ultimaker.com/firmware, and select your printer
    1. Download the firmware image and store it in the root directory of your USB stick
    1. Insert the USB stick into the USB port of the printer
    1. In the Settings menu, go to Update firmware and select the new firmware from the USB device Do not power off the printer during the firmware installation.

Material handling and storage

Opened material spools must be stored properly when not in use. If material is stored incorrectly, it may affect its

quality and usability.

The optimal storage temperature for PLA, Tough PLA, Nylon, CPE, CPE+, PC, TPU 95A, and PP is between -20 and

+30 °C. For ABS, the advised temperature is between 15 and 25 °C. Furthermore, a relative humidity of below 50% is recommended for TPU 95A and PP. If these materials are exposed to a higher humidity, the quality of the material can be affected.

To keep your materials in optimal condition, opened spools should be stored:

  • Cool and dry
    • Out of direct sunlight
    • In a resealable bag

To minimize moisture absorption, store the material in a resealable bag including the supplied desiccant (silica gel) directly after printing.

Replace the Air Manager filter

The filter in the Air Manager is a consumable. It should be replaced every 1,500 printing hours to maintain  proper filtering.

Do not change the filter of the Air Manager while the fan is in operation. Turn off the printer to make sure the

fan cannot start unexpectedly.

The function of the Air Manager’s filter is to reduce the emission of ultrafine particles. These particles will remain in the filter. The used filter should be handled with care during the replacement procedure. If the used filter is not properly handled, there is a risk of the ultrafine particles being released.

  1. Remove the Air Manager cover
  2. Take out the used filter by pulling the tab on the filter towards you and removing it from the filter housing
  3. Directly place the used filter in a (resealable) bag and close it
  4. Insert the replacement filter into the filter housing and gently push it. Ensure the filter is completely flush
  5. Place the Air Manager cover onto the printer and turn on the Ultimaker 2+ Connect

The filter in the sealed bag can be disposed of with your regular household waste.
