Ultimaker S-line safety and compliance

Note: An official PDF version of each safety and compliance document of the Ultimaker S-line printers is available for download.

General safety information

  • The Ultimaker S3 and Ultimaker S5 generate high temperatures and have hot moving parts that can cause injury. Never reach inside of the Ultimaker S3 and Ultimaker S5 while they are in operation. Always control the printers with the touchscreen at the front or the power switch at the back. Allow the Ultimaker S3 and Ultimaker S5 to cool down for 5 minutes before reaching inside.
  • Do not change or adjust any parts of the Ultimaker products unless the change or adjustment is authorized by the manufacturer
  • Do not store items inside the Ultimaker products, except for compatible filament spools in the Material Station
  • Ultimaker products are not intended for use by persons with reduced physical and/or mental capabilities, or lack of experience and knowledge, unless they are supervised or have been given instructions concerning the use of the appliance by a person responsible for their safety
  • Children should be under constant supervision when using the Ultimaker products
  • Do not touch the fan of the Air Manager when changing the filter


Electromagnetic compatibility (EMC)

These devices may not cause harmful interference, and these devices must accept any interference received, including interference that may cause undesired operation.

An electrostatic discharge in some metallic parts of the devices may cause the interruption of the NFC communications, affecting the initial detection of the material spool. In these cases, a device restart should solve the problem.

Electrical safety

Ultimaker products have been tested according to the IEC 60950-1 and/or IEC 62368-1. All relevant products have undergone and passed Hi-pot testing before shipment. This test guarantees the right level of insulation against electrical shock. An earthed mains socket must be used. Be sure that the building installation has dedicated means for over-current and short-circuiting.

The printer is powered by mains voltage, which is hazardous when touched. This has been marked with a high-voltage symbol on the bottom cover. Only trained staff should remove the bottom cover.

Always unplug the Ultimaker products before performing maintenance or modifications.

Mechanical safety

Ultimaker products are compliant with the Machine Directive 2006/42/EU. The EC Declaration of Conformity can be found at the bottom of this page.

The Ultimaker S3 and Ultimaker S5 contain moving parts. No damage to the user will be expected from the drive belts. The force of the build plate is large enough to cause damage, so stay out of the reach of the build plate during operation.

Always unplug the Ultimaker products before performing maintenance or modifications.

Risk of burns

There is a potential risk of burns: the print head of the Ultimaker S3 and Ultimaker S5 can reach temperatures up to 280 °C, while the heated bed can reach temperatures of 140 °C. Do not touch either of these parts with your bare hands.  

Always allow the Ultimaker products to cool down for 30 minutes before performing maintenance or modifications.

Health and safety

3D printing thermoplastics may result in the release of Ultra Fine Particles (UFPs) and Volatile Organic Compounds (VOCs) depending on the thermoplastic used and settings of the 3D printer.

Ultimaker products are designed for use with Ultimaker materials and are open for use with materials from third-party suppliers.  

Ultimaker materials

Ultimaker materials can be printed safely without any filtering using the recommended temperatures and settings in a well-ventilated area (minimum refresh rate of 1.8 for a room size of 30.6 m3). When multiple Ultimaker 3D printers are operated in a contained environment, emissions of UFPs and/or VOCs may vary. Please consider other safety measures, such as a filter, cabinet, and/or dedicated ventilation system depending on your specific situation.  

Third-party materials

Third-party material manufacturers can supply print profiles that contribute to reliable results with Ultimaker hardware (“The Ultimaker Material Alliance Program” and Certified materials).  

The use of print profiles and materials from Ultimaker’s Material Alliances and/or other suppliers may require additional safety measures such as a filter for the safe usage of such materials. Please take the relevant information provided by the supplier of such filament/material into account at all times for safe operation. Please check the safety data sheet of each specific material for information.  

Ultimaker cannot be held responsible for any adverse effects from the use and/or performance of these materials.
