Safety and compliance

General safety information

The Ultimaker S5 generates high temperatures and has hot moving parts that can cause injury. Never reach inside of the Ultimaker S5 while it is in operation. Always control the printer with the touchscreen at the front or the power switch at the back. Allow the Ultimaker S5 to cool down for 5 minutes before reaching inside.

Do not change or adjust anything on the Ultimaker S5 unless the change or adjustment is authorized by the manufacturer.

Do not store items inside the Ultimaker S5.

The Ultimaker S5 is 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 instruction concerning the use of the appliance by a person responsible for their safety.

Children should be under constant supervision when using the printer.

Intentional radio

This device may not cause harmful interference, and this device must accept any interference received, including interference that may cause undesired operation.


Electromagnetic compatibility (EMC)

This equipment has been tested and found to be compliant with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

An electrostatic discharge in some metallic parts of the device 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

The Ultimaker S5 has been tested according to the IEC 60950-1. Every printer has 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. For more information, please look at our website for the CB-report. 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 printer before doing maintenance or modifications.

Mechanical safety

The Ultimaker S5 complies to the Machine Directive 2006/42/EU. The EC declaration of conformity can be found on our website. The Ultimaker S5 contains moving parts. No damage to the user will be expected from the drive belts. The force of the build plate is big enough to give some damage, so keep hands out of the reach of the build plate during operation.

Always unplug the printer before doing maintenance or modifications.

Risk of burns

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

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

Health and safety

The Ultimaker S5 is designed for Ultimaker material. These materials can be printed safely if the recommended temperatures and settings are used. We recommend to print all Ultimaker materials in a well-ventilated area. Please check the SDS of each specific material for more information.

Third-party materials can release VOCs (volatile organic compounds) above regulated threshold limit values when processed in Ultimaker 3D printers (not covered by warranty). These can cause headaches, fatigue, dizziness, confusion, drowsiness, malaise, difficulty in concentration, and feelings of intoxication. Usage of a fume hood is recommended. Look at the SDS of these materials for more information.
