Intended use
Ultimaker 3D printers are designed and built for fused lament fabrication with Ultimaker materials mainly within
a commercial, professional, or educational environment. The mixture of precision and speed makes Ultimaker 3D
printers very suitable for concept models, functional prototypes, and small series production.
The Ultimaker 2+ Connect, with its networking capabilities and new touchscreen, delivers single extrusion for
simple applications.
Although we achieved a very high standard in the reproduction of 3D models with the usage of Ultimaker Cura,
the user remains responsible to qualify and validate the application of the printed object for its intended use. This
is especially critical for applications in strictly regulated areas like medical devices and aeronautics. While being
an open material platform, the best results will be achieved with Ultimaker materials, as eort has been made to
match material properties with machine settings.

4.2 Materials
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 proles in Ultimaker Cura to ensure
the best print results. Therefore, it is advised to use one of the default proles in Ultimaker Cura for the
highest reliability.
Print recommendations
Each material requires dierent 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 ultrane particles (UFPs) and volatile organic
compounds (VOCs) depending on the laments used and settings of the 3D printer. In case UFP emissions are
unknown or are likely to be signicant, 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 laments 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 specic conditions under which the printer(s) are used.

4.4 Printing with the Air Manager
The optional Ultimaker 2+ Connect Air Manager is designed to simply and eectively increase user safety. The Air
Manager consists of the top cover, lter, 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 signicant
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:
• UFPltering. The Air Manager encloses the top and front of the Ultimaker 2+ Connect and ensures an inside-
out airow. The air passes through an E10 lter whereby ultrane 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 inuence the print result
The Air Manager will only work properly if all components are installed correctly. Ensure there are no gaps
between the lter 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 nished, wait until the printer has completely cooled down. This will allow sucient time to
lter all particles from the printing process. Then remove the front enclosure so you can take the nished 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 prole of the front enclosure.
Ultimaker 2+ Connect user manual 24
4.5 Remove the print
Once your 3D print is nished 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 o the plate.
Alternatively, you can run lukewarm water over the print side of the plate to dissolve the glue.
Conrm removal
Once the print has been removed and the build plate is placed back in the printer, conrm 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 conrm 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.

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 lament 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 lament manually.
2. Place the print head in the middle of the gantry for easy access
3. Set the nozzle temperature to 100 ºC
4. 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.
5. Select the desired nozzle and manually screw it into the heater block until it is hand-tight

Ultimaker 2+ Connect user manual 29
5.4 Replace the Air Manager lter
The lter in the Air Manager is a consumable. It should be replaced every 1,500 printing hours to
maintain proper ltering.
Do not change the lter of the Air Manager while the fan is in operation. Turn o the printer to make sure the
fan cannot start unexpectedly.
The function of the Air Manager’s lter is to reduce the emission of ultrane particles. These particles will
remain in the lter. The used lter should be handled with care during the replacement procedure. If the used
lter is not properly handled, there is a risk of the ultrane particles being released.
1. Remove the Air Manager cover
2. Take out the used lter by pulling the tab on the lter towards you and removing it from the lter housing
3. Directly place the used lter in a (resealable) bag and close it
4. Insert the replacement lter into the lter housing and gently push it. Ensure the lter is completely ush
5. Place the Air Manager cover onto the printer and turn on the Ultimaker 2+ Connect
The lter in the sealed bag can be disposed of with your regular household waste.

6. Troubleshooting
6.1 Error messages
When the printer detects that something is wrong, or when it reads values outside of the allowed range,
an error will occur. The display will give a short description of the detected issue along with its unique
error code. For example:
• Detected nozzle temperature is invalid. Go to ultimaker.com/ER201
Go to the specied page to learn more and for troubleshooting tips.
6.2 Extrusion problems
If the Ultimaker 2+ Connect is not extruding the correct amount of material, or not extruding any material at all,
there can be multiple causes for this. Try the following troubleshooting tips.
Clean the inside of the nozzle
If material does not ow consistently, the nozzle could be clogged with degraded material. In this case, the nozzle
should be cleaned by performing the hot and cold pull method. You can use cleaning lament or PLA for this.
Cleaning lament can be used to clean the nozzle of the Ultimaker 2+ Connect by applying hot and cold pulls.
Hot pulls are used to get the biggest parts of degraded material out of the nozzle and are especially necessary
when the nozzle is clogged. With a cold pull, the remaining small particles will be pulled out, ensuring the nozzle
is completely clean.
A cold pull is also recommended when switching to a dierent material type or when changing the nozzle.
This procedure requires heating up the nozzle. Be careful and do not touch the nozzle. Protective
(thermal) gloves are advised.
Ensure the Ultimaker 2+ Connect is disconnected from the Digital Factory or made unavailable
for new print jobs.
Preparation
1. Start by removing the material. Navigate to Materials → Unload material and remove the spool
2. Place the print head in the front-right corner
3. Remove the clamp clip from the print head, press down on the tube coupling collet and pull the Bowden tube
upwards out of the print head
4. On the display, navigate to Maintenance → Set nozzle temperature
5. Use the controls to set the target temperature to 260 °C for cleaning lament, or 235 ºC for PLA
6. Wait for the nozzle to heat up
Hot pull
Use pliers to hold the material to prevent injury to your hands in case the material breaks.
1. Insert the cleaning lament (or a length of approximately 20 cm of PLA lament) into the print head until you
feel some resistance
2. Hold the lament with pliers and gently apply pressure to the material for ±1 second so that it extrudes from
the nozzle or until it cannot be pushed any further, and directly pull the lament out with a quick, rm pull
3. Cut o the tip of the lament that you have just pulled out
4. Repeat this procedure until there is no more degraded material visible on the tip of the cleaning lament.
5. Insert the lament into the print head again and ush some material through the nozzle
Ultimaker 2+ Connect user manual 32
Cold pull
1. In the Set nozzle temperature menu, use the controls to lower the nozzle temperature to 135 ºC for cleaning
lament, or 90 ºC for PLA
2. Continue to apply some pressure on the material in the print head with pliers
3. When the nozzle has reached the target temperature, use the pliers to pull out the lament
with a quick, rm pull
4. Inspect the tip of the lament. If it has a clean, cone-shaped tip like the image below, the nozzle was
successfully cleaned
If the tip of the material is not clean, raise the temperature again and repeat the cold pull steps.
Finish the procedure
1. Lower the nozzle temperature to 0 ºC and wait for the nozzle to cool down
2. Insert the Bowden tube into the print head by pressing down on the tube coupling collet in the print head and
pushing the Bowden tube all the way in
3. Pull the Bowden tube and tube coupling collet approximately 2 mm upwards. Keep the tube coupling collet up
and push the Bowden tube further in
4. Secure the tube with the clamp clip
Check the TFM coupler
The TFM coupler (the white part in the Ultimaker 2+ Connect hot end) can deform. The coupler is a consumable
item that wears over time and slowly changes shape on the inside due to heat and pressure in the hot end.
Eventually, this will cause friction to the material that has to pass through and causes under-extrusion.
Checking the condition of the TFM coupler requires disassembling the Ultimaker 2+ Connect print
head. Instructions on how to do this and how to replace the TFM coupler when necessary are found on
the Ultimaker website.
Check the feeder
Extrusion problems can also be related to the feeder. Clean the feeder and Bowden tube according to the
maintenance instructions. Additionally, check if the feeder tension is set correctly. For all Ultimaker materials, the
tension indicator should be set to the middle mark.
Use the hex screwdriver to turn the bolt in the top of the feeder to adjust the position of the tension indicator.
If you have an Air Manager, it must be uninstalled rst in order to reach this bolt.
6.3 Adhesion issues
Adhesion problems can include the print not sticking to the build plate or warping of the material during printing.
When you experience problems with the adhesion of a print to the build plate, the following things can be done:
• Ensure that the correct adhesion method was used. See the Ultimaker website for the recommended adhesion
methods per material
• Level the build plate to ensure the distance between the nozzle and build plate is correct. Navigate to
Maintenance → Level build plate and follow the instructions on the display
• Check the Ultimaker Cura settings that were used and try printing with one of the default
Ultimaker Cura proles
The use of the Air Manager is highly recommended. It ensures a closed environment and can improve the
adhesion, especially with engineering materials.
Ultimaker 2+ Connect user manual 33
6.4 Air Manager troubleshooting
Air Manager not recognized
You can check if the Air Manager is detected by the Ultimaker 2+ Connect in the Diagnostics menu. Navigate
to Maintenance → Diagnostics to check the Air Manager status. If the Air Manager is installed, but listed as ‘not
present’, it may not be connected properly. Follow the steps below to check the Air Manager cable:
1. Power o the Ultimaker 2+ Connect
2. Ensure one end of the Air Manager cable is securely inserted into the lter housing. Reconnect if necessary
3. Ensure the other end of the cable is securely inserted into the OUT port at the back of the Ultimaker 2+
Connect. Reconnect if necessary
4. Turn the Ultimaker 2+ Connect on again. If the Air Manager is still not recognized, go to support.ultimaker.com
and submit a support ticket
Fan is not spinning
If the fan of the Air Manager is not spinning correctly, the Air Manager will not be able to properly lter all particles
from the printing process. This may also lead to too high temperatures inside the printer. In case of problems with
the fan, check for obstructions:
1. Check if the lter is installed correctly
2. Check at the back if anything is interfering with the fan
3. Ensure at least 10 cm of free space behind the Ultimaker 2+ Connect and Air Manager for unrestricted airow
If this does not help to resolve the problem, go to support.ultimaker.com and submit a support ticket.
