Still, it is advised to only reach in the machine when it is turned off.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 canreach temperatures of up to 120°C. The nozzle of the print head is mostly surrounded by an aluminum cover to preventcontact, but we still advise against reaching into the machine when the print head and/or heated bed are hot.Always let the printer cool down for at least 30 minutes before performing 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 with ABS, small concentrations of Styrene vapor can be released. In some cases, this can causeheadaches, 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 hoodwith active carbon filtering for ductless extraction. Fume extraction is mandatory for use in offices, classrooms, etc.Printing with pure PLA is considered safe, although good ventilation is still advised for possible unknown vaporsreleased from coloring dyes in colored PLA.Only use your printer in a well-ventilated area.HAZARDS
