<p>Bed heating is not required when printing in PLA. But if it is an option and you would like to heat the bed, I would not go above 70/80 °C for PLA.

<p>The answer is that it <a href="/a/1508/">depends</a> on the hotend temperature the area of the printed layer and the effectivity of the fan. It is best to print some test prints to find the optimum for your printer. E.g. prints with overhangs/slanted object are good tests for this.

<p>Yes, PLA doesn't shrink much, so it doesn't necessarily need to be heated up to the glass transition temperature (temperature at which the filament becomes soft) of the plastic. It does require to take extra measures to get it to stick to the bed surface. You also don't want the bed temperature to be too high, this will manifest in poor first few layers quality, similar to elephant feet phenomenon.</p>

<p>I'd not take it further then 60 °C, if higher, the PLA will become really soft and may cause printing problems known as &quot;elephants feet&quot;.</p>

What slicer are you using?  Cura 4.9 that I use at home handles fans automatically, do you have reason to believe the defaults are wrong?  What brand/color/type PLA do you have?

What fan speed should I use with PLA? Do I need to manually set the fan speed in ‘Control’?

Also, on the filament cartridge Bed Temp is listed: *"No heat/60-80 °C"*. Does this mean heating the bed is optional?

The answer is that it [depends](/a/1508/) on the hotend temperature the area of the printed layer and the effectivity of the fan. It is best to print some test prints to find the optimum for your printer. E.g. prints with overhangs/slanted object are good tests for this. Normally a Benchy is not a calibration object, but the bow of the Benchy is an example; incorrect temperature (too hot) and too few cooling will result in the bow sagging out.

I'd not take it further then 60 °C, if higher, the PLA will become really soft and may cause printing problems known as "elephants feet".
