Frequently Asked Questions
What is the maximum flow of my printer?
It depends entirely on your hotend. A standard hotend (V6-type) typically melts between 10 and 12 mm³/s. High-flow models like Volcano or Revo High Flow reach 30-35 mm³/s.
Why does PETG flow slower than PLA?
PETG has much higher viscosity when molten. This means it offers more resistance passing through the nozzle, so its effective flow limit is typically 15% lower than PLA at the same temperature.
How does line width affect flow?
Line width is the most direct multiplier along with layer height. If you go from 0.4mm to 0.6mm width at the same speed, you're demanding 50% more flow from your extruder.
