The Ultimaker 2 safety and compliance

Intended use

Ultimaker 3D printers are designed and built for Fused Filament Fabrication for various high quality plastics like PLA, ABS, CPE within a commercial/business environment. The mixture of precision and speed makes the Ultimaker 3D printers the perfect machines for concept models, functional prototypes and also the production of small series. Although we achieved a very high standard in the reproduction of 3D models with the usage of Cura, the user remains responsible to qualify and validate the application of the printed object for its intended use. While being an open filament platform the best results will be achieved with Ultimaker certified filament, while effort has been made in order to match material properties with machine settings.

Electromagnetic compatibility (EMC)

This equipment has been tested and found to comply 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 can radiate unintentional radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause interference to radio communications. Operation of this equipment in a residential area may cause interference in which case the user will be required to correct the interference at his own expense.

Electrical safety

The Ultimaker 2 operates on 24 volts (Extra-low-voltage) and is therefore outside the scope of the low-voltage directive. The power supply meets all CE mark regulations and is protected against short-circuit, overload, over voltage and over temperature. For more information concerning electrical safety aspects we refer you to the Mean Well EC-Conformity Declaration for the GS220AX power adapters.

Only use the Ultimaker 2 with power supplies and cables supplied by Ultimaker B.V..

Caution: Always unplug the printer before doing maintenance or modifications.

Mechanical safety

The Ultimaker 2 contains many moving parts, but the stepper motors do not have enough power to cause serious injuries and moving gears have been covered. Still, it is advised to only reach in the machine when it is turned off.

Caution: Always unplug the printer before doing maintenance or modifications.

Risk of burns

There is a potential risk of burns, as the print head can reach temperatures of up to 260°C and the heated bed of up to 120°C. The nozzle of the print head is mostly surrounded by an aluminum cover to prevent contact, but still we advise against reaching in the machine when the print head and/or heated bed are hot.

Caution: Always let the printer cool down for at least 30 minutes before doing maintenance or modifications.


The Ultimaker 2 is designed to print with PLA and ABS filaments. The use of other materials is at your own risk.

When printing ABS, small concentrations of Styrene vapor can be released. This can (in some cases) cause headaches, fatigue, dizziness, confusion, drowsiness, malaise, difficulty in concentrating, and a feeling of intoxication. Therefore good ventilation is required, and long term exposure should be avoided. It is advisable to use a fume hood (with active carbon filtering for ductless extraction). Fume extraction is mandatory for use in offices, classrooms and alike.

Printing pure PLA is considered safe, although good ventilation is still advised for possible unknown vapors released from coloring dyes in colored PLA.

Caution: Only use your printer in a well-ventilated area.

General safety information

The Ultimaker 2 is not intended for use by persons (including children) with reduced physical and/or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.

Children should be under constant supervision when using the printer.
