PolyLite PETG is an affordable PETG filament with balanced mechanical properties and ease of printing. What is PETG? If we had a simple axis going from "low durability but easy to print" on the left to "high durability but challenging to print" on the right. PLA would be in the far left, ABS would be in the far right and PETG would be exactly in the middle. Printing temperature: (PLA+ABS)/2 Heat resistance: (PLA+ABS)/2 Strength: (PLA+ABS)/2 Feel free to check our TDS below for more scientific information. Printing and Drying Settings? Printing Temperature: 230C - 240C Bed Temperature: 70C - 80C Printing Speed: 30mm/s - 50mm/s Fan: 20% Direct Drive: Retraction Distance: 1mm Retraction Speed: 20mm/s Indirect Drive: Retraction Distance: 3mm Retraction Speed: 40mm/s Drying Settings: 65C for 6h (Only if the material has absorbed moisture) Do I need to use the cooling fan with PETG? Yes if you are looking for nice surface finish. No if you are looking for strong and durable parts. 20% ON if you want the best of both worlds.
