Recommended Temperature
The recommended operating temperature for your 3D printer is between 0°C to 40°C (32°F to 104°F). If the ambient temperature is too high, though beneficial to print results in some cases, it will damage the 3D printer components. Use fans or air conditioners to lower the ambient temperature if necessary.
If the ambient temperature is too low, it will take longer to heat up before you print. Another adverse impact is that the print will easily warp. Affected by cool air, the top layers of the extruded filament contract; whereas the bottom layers kept heating up by the Heated Bed will expand and thus warp. Use enclosures or air conditioners to raise the ambient temperature if necessary.
Recommended Humidity
Extreme humidity is harmful to the 3D printer. The recommended relative humidity for your 3D printer is between 30% to 70%. In extremely damp conditions, the 3D printer will be damaged due to dampened components. In extremely dry conditions, the 3D printer under static interference may execute wrong operations. Use dehumidifiers or humidifiers to keep the relative humidity at a recommended range if necessary.
