Do you need a fan for printing PLA?

Cooling is one of the most important aspects of printing with PLA. Having a dedicated part cooling fan makes a huge difference in the quality of the printed parts. The freshly extruded plastic needs to cool down below the glass transition temperature as quickly as possible.

How does fan speed affect PLA?

What is this? The fan speed parameter provides a tradeoff between surface quality and strength for all types of filaments, and PLA is no exception to this rule, where higher fan speed values provide higher surface quality, and lower fan speed values provide better strength.

Do filament printers need ventilation?

While not harmful in small portions, breathing in styrene on a regular basis can be harmful to the human body. Therefore, ventilation is needed anytime the 3D printing process is initiated.

Does a Hotend need a fan?

The Mosquito hotend can function without active cooling (a fan) under certain conditions, but it is advisable to use a fan when printing with PLA and other lower temperature plastics (PETG, ABS, etc). The cooling fan can be positioned on either side of the heat sink, but it must face the heat break.

Is it better to 3D print in hot or cold room?

Rather a temperature range is to be kept in mind. But the most foremost factor to practice is temperature stability. Hence, for good print output and overall performance, it’s best you maintain an optimum room temperature preferably around 62-68°F (17-20°C).
