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 BURNSThere is a potential risk of burns, as the print head can reach temperatures of up to 260°C and the heated bed of up to120°C. The nozzle of the print head is mostly surrounded by an aluminum cover to prevent contact, but still we adviseagainst 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.HEALTHThe 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. Thereforegood ventilation is required, and long term exposure should be avoided. It is advisable to use a fume hood (with activecarbon 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 releasedfrom coloring dyes in colored PLA.CAUTION: Only use your printer in a well-ventilated area.
