The best temperature will rely on the type of PLA you’re using and your 3D printer, but the range for PLA is around 210 ⁰C, but it also works well anywhere between 190 to 230 ⁰C depending on what you need. Your 3D prints should have great results as long as they don’t stray away from either direction. Do not forget to keep your cooling fans on while printing as the best results are produced with proper cooling.
