eSUN 3D Printer Filament: PLA PRO (PLA+) Extrusion Temperature Range: 205 to 225 Celsius PLA PRO(PLA+) Advantages: Superb layer bonding High rigidity. Good glossiness. Several times tougher than PLA Smoother finished printouts. No cracking or brittleness problems. Prints are hard to break. PLA PRO(PLA+) print temperature is about 20 Celsius higher than regular PLA. Most users print at around 215 to 225 Celsius. PLA+ has a low shrinkage rate and sticks very well both to bed and layer to layer.
