Frequently Asked Questions
Why does PETG string more than PLA?PETG has different material properties, such as higher viscosity and moisture absorption, which contribute to increased stringing compared to PLA.
How can I reduce stringing when printing with PETG?Adjusting retraction settings, lowering printing temperature, and drying the filament can help minimise stringing in PETG prints.
What are the key differences between PETG and PLA that affect stringing?PETG is more prone to stringing than PLA due to its higher melt flow index, greater surface tension, and sensitivity to moisture.
