When turned on for the first time, the Ultimaker S3 / S5 will run the welcome setup. After this, the main menu will be shown when the printer is turned on.

Interface

The main menu offers three options, represented by the following icons:

The status overview is automatically shown next to the main menu. From here, you can start a print from USB, or view the progress of the print while printing

The configuration overview shows the current configuration of the printer. Here you can see which print cores and materials are installed, as well as change the  configuration

The preferences overview consists of three sub-menus: settings, maintenance, and network. In the printer settings menu, you can change general settings, such as the language. In the maintenance menu, you can perform the most important maitenance and calibration procedures, in addition to saving logs for diagnostics. The network menu allows you to change network settings or to perform the Wi-Fi   setup

Materials

Material compatibility

The Ultimaker S3 / S5 comes with two AA print cores and one BB print core. The AA print cores can be used for printing build materials and Breakaway support material. The BB print core can be used for water-soluble support material (PVA).

The Ultimaker S3 / S5 support all Ultimaker materials that are currently available, of which most can be printed with the 0.25, 0.4 and 0.8 mm print core sizes. The print core CC Red 0.6 can be used for third party composite materials.

For an overview of possible dual-extrusion material combinations, please refer to the Ultimaker website.

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. Using Ultimaker materials will also allow you to benefit from the NFC detection system. Ultimaker spools will automatically be recognized by the Ultimaker S3 / S5. This information can be directly transferred

to Ultimaker Cura when connected to a network, allowing for a seamless connection between the printer and Ultimaker Cura software.

Print recommendations

Each material requires different settings for optimal results. If you use Ultimaker Cura to prepare your model, these settings are automatically set correctly if the correct print core(s) and material(s) 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. For detailed instructions on which settings and adhesion method to use per material, take a look at the material manuals on the Ultimaker website.

Preparing a print with Ultimaker Cura

Interface

After you have added the Ultimaker S3 / S5 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 stage.

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

When printing with a networked printer, the loaded configuration is detected. You can select this configuration to prepare your print faster.

  • 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 printing with support, you have the option to select the extruder that you want to use to print the support structure. This allows you to print your model with PVA support, Breakaway support, or build material support.

  • 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

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 3D printer.

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 user manual found on the Ultimaker website.

Monitor stage

The monitor stage utilizes the Ultimaker Connect 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 directly from Ultimaker Cura to the printer. 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.

Ultimaker Cloud

The Ultimaker S3 / S5 benefits from integration with Ultimaker Cloud. To make the most out of your Ultimaker printer, you must first associate the printer with your Ultimaker account.

For more information on the Ultimaker cloud, visit mycloud.ultimaker.com.

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.

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.

Use a spatula

If your print is still adhered to the build plate after cooling, you can use a spatula to remove the print. 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, but be careful if it is still warm. 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. If PVA was used, place the build plate and print in water to dissolve the PVA. This makes print removal easier.

Once the print has been removed and the build plate is placed back in the printer, select Confirm removal on the display of the Ultimaker S3 / S5. This will allow the next print job to start.

Remove support material

Dissolve PVA support

PVA support structures can be removed by dissolving the PVA in water. This takes several hours and leaves no trace afterwards. Follow the steps below and refer to the Ultimaker website for additional tips and information.

  1. Submerge the print in water to let the PVA dissolve
  2. Rinse the print with clean water to remove any excess PVA
  3. Let the print dry completely
  4. Dispose of the waste water

PVA is a biodegradable material, and in most cases disposing the water afterwards is easy. However, it is recommended that you check local regulations for more comprehensive guidance. The water can be disposed of down the drain, providing the waste water distribution network is connected to a wastewater treatment plant. After disposal, run hot water from the tap for approximately 30 seconds to remove any excess saturated PVA water and to avoid longer-term clogging issues.

It is possible to use the water for more than one print, however, this might extend the dissolving time. Through repeated use, water becomes saturated by previously dissolved PVA. For the quickest result, fresh water is recommended.

Remove Breakaway support

Prints using Ultimaker Breakaway as support material will require post-processing to remove the support structures. This can be achieved by breaking the support structures from the build material. Follow the steps below and refer to the Ultimaker website for additional tips and information.

It is advised to wear protective gloves when the support structure contains sharp corners or when working with larger models.

  1. Tear away the majority of the inner support structure using pliers
  2. Use cutting pliers to grip the Breakaway support interface and pull it away from the model
  3. Remove the last traces of the Breakaway support using cutting pliers or tweezers

Change the printer configuration

  • Wait for the Ultimaker S3 / S5 to heat up the print core and to load the material into the print head
  • Confirm when the new material extrudes consistently from the print core
  • Wait a moment for the print core to cool down

Change print core

Print cores can be easily changed on the Ultimaker S3 / S5 by using the procedure from the menu. Besides changing print cores, you also have the option to only load or unload a print core:

  1. Go to the configuration menu, select the print core you want to change and select Change
  2. Wait for the print core to heat up, unload the material, and cool down again
  3. Open the glass door(s) of the Ultimaker S3 / S5 and the print head fan bracket and Confirm when completed
  4. Remove the print core carefully by squeezing the levers and sliding the print core out of the print head Do not touch the contact points on the back side of the print core with your fingers.

Make sure you keep the print core completely vertical while removing or installing it so it will smoothly slide into/out of the print head.

  • Insert a print core by squeezing the levers of the print core and sliding it into the print head slot until you hear a click

It is possible that the print core includes a ring around the nozzle. Remove this nozzle ring before using the print core on the Ultimaker S3 / S5. Learn more about this on the Ultimaker website.

  • Carefully close the print head fan bracket and Confirm when completed
  • Wait for the Ultimaker S3 / S5 to load the material into the print core

Calibration

Build plate leveling

While using the Ultimaker S3 / S5, build plate calibration should be performed to ensure reliable adhesion of the print to the build plate. If the distance between the nozzles and build plate is too wide, your print won’t adhere properly to the glass build plate. On the other hand, if the nozzles are too close to the build plate, it can prevent material from extruding.

Make sure there is no excess material below the tip of the nozzles and the build plate is clean before the start of a print or when you want to calibrate the build plate, or you might get inaccurate results.

Active leveling

Active leveling is automatically performed by the printer at the start of a print, to create a reliable first layer. During active leveling, the Ultimaker S3 / S5 will create a detailed heightmap of the build plate surface. This information

is used to compensate for any inaccuracies of the build surface during the first layers of the print. It will do this by adjusting the build plate height while printing.

Do not touch the Ultimaker S3 / S5 during the active leveling procedure, as this could affect the calibration process.

Manual leveling

Perform manual leveling when the level of the build plate is too far out of range for active leveling to compensate for.

  1. Go to Preferences Maintenance Build plate Manual leveling and select Start
  2. Wait while the Ultimaker S3 / S5 prepares the manual leveling procedure
  3. Use the touchscreen controls to move the build plate until there is approximately 1 mm distance between the first nozzle and the build plate. Make sure that the nozzle is close to the build plate without touching it. Select Confirm to continue
  4. Adjust the front-right thumb wheel to roughly level the front of the build plate. There should be a distance of

approximately 1 mm between the nozzle and build plate

  • Repeat step 4 for the front-left thumb wheel and select Confirm to continue
  • Place the calibration card inbetween the nozzle and build plate. Use the touchscreen controls to adjust the position of the build plate until you feel some resistance when moving the card. Select Confirm to continue

Do not apply force to the build plate while fine-tuning with the calibration card, as this will lead to leveling inaccuracies.

  • Place the calibration card between the nozzle and build plate in the front right corner. Adjust the thumb wheel until you feel some resistance when moving the card. Select Confirm to continue
  • Repeat step 7 for the front left corner and select Confirm to continue

After calibrating the build plate with the first nozzle, the second nozzle needs to be aligned as well, to ensure the heights of both nozzles are set correctly. For this it is only necessary to set the correct height by using the calibration card.

  • Place the calibration card in between the second nozzle and build plate. Use the controls to adjust the position of the build plate until you feel some resistance when moving the card. Select Confirm to continue
  • Wait for the printer to finish the manual leveling procedure

XY offset calibration

Besides the vertical offset, the horizontal distance between the nozzles in the X and Y direction also needs to be configured. The print cores that are supplied with the Ultimaker S3 / S5 are already calibrated, but when the printer detects a new combination, you will need to perform an XY offset calibration. This calibration must only be done once; after this, the information is stored on the printer. A correct XY calibration will ensure that the two colors or materials align well.

To perform the calibration you will need an XY calibration sheet, which can found in the accessory box or downloaded at ultimaker.com/XYcalibration.

Ensure 2 print cores and materials are installed before starting the calibration.

  1. Go to Preferences Maintenance Print head Calibrate XY offset and select Start calibration
  2. The Ultimaker S3 / S5 will now print a grid pattern on the build plate. Wait until it is complete
  3. Once the Ultimaker S3 / S5 has cooled down, remove the build plate from the printer and align it with the XY calibration sheet. Ensure the printed grid is precisely placed on the two rectangles on the sheet
  4. Find the best aligned lines on the printed X grid and note which number corresponds to these lines. Enter this number as the X offset value on your Ultimaker S3 / S5
  5. Find the best aligned lines on the printed Y grid and note which number corresponds to these lines. Enter this number as the Y offset value on your Ultimaker S3 / S5

It is important that the printed XY offset pattern adheres well to the build plate and shows no signs of under- extrusion. If it did not print well, it is recommended to repeat the calibration print.

Lift switch calibration

The switch bay enables the second print core to be lifted and lowered. For successful dual-extrusion prints, it is important that print core switching functions well. The lift switch is already calibrated when the Ultimaker S3 / S5 is shipped, but calibration can also be performed manually if needed.

  1. Go to Preferences Maintenance Print head Calibrate lift switch and select Start calibration
  2. Move the lift switch on the side of the print head to point towards you. Select Confirm to continue
  3. Move the print head so that the lift switch fits in the switching bay. Select Confirm when completed
  4. Wait for the print head to go to the home position and test the lift switch
  5. Did the lift switch lower and raise the print core? If so, press Yes to complete the calibration. If not, select No to perform the calibration again

Maintenance

Update the firmware

Periodically, a new version of the Ultimaker S3 / S5 firmware is released. To ensure that your Ultimaker S3 / S5 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 S3 / S5 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 System Maintenance Update   firmware.

Do not power off the printer during the firmware installation.

Update using a USB stick

If your Ultimaker S3 / S5 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. Go to Preferences Maintenance Update firmware and select the new firmware in the update menu

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, PP, and Breakaway is between

-20 to +30 °C. For ABS, the advised temperature is between 15 and 25 °C, and for PVA 0 to 30 °C. Furthermore, a relative humidity of below 50% is recommended for PVA, TPU 95A, PP, and Breakaway. 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.
