This profile is designed for printing with PolyMaker PolyLite PETG using Prusa Slicer. It is ideal for makers and engineers seeking a reliable, beginner-friendly PETG setup that balances print quality, strength, and consistent results. The profile is tuned to minimize stringing and maximize layer adhesion, making it suitable for a wide range of functional and outdoor parts.
The profile leverages PETG’s natural durability and ease of use by setting a hotend temperature of 230–235 °C and a bed temperature of 80 °C. Retraction is carefully tuned to 2–3mm to reduce stringing, while fan speeds are limited to 30–50% to improve layer bonding. These adjustments help ensure prints are strong, clean, and dimensionally accurate, even for users new to PETG.
Temperature: The hotend is set to 230–235 °C, which is optimal for PolyLite PETG, ensuring smooth extrusion and strong layer adhesion. The bed is heated to 80 °C to prevent warping and improve first layer bonding.
Retraction: Retraction distance is set between 2–3mm, which helps minimize stringing—a common issue with PETG—without causing jams or under-extrusion.
Cooling: The part cooling fan is reduced to 30–50%. Lower fan speeds help PETG layers fuse better, resulting in stronger prints and improved surface finish.
Layer Height and Quality: The profile uses a standard 0.2mm layer height for a good balance of speed and detail, with 2 perimeters for strength.
Infill and Bed Adhesion: Infill is set to approximately 25%, providing structural integrity without excessive material use. A skirt is used for bed adhesion, helping to prime the nozzle and reduce the risk of first layer issues.
