This profile is designed for printing with Atomic Filament PETG 1.75mm using Cura. It is tailored for makers and engineers who require precision and reliability when producing small, functional mechanical parts. The settings focus on delivering high print quality, strong layer adhesion, and minimal stringing, making it suitable for demanding applications where both strength and detail matter.
The tuning logic behind this profile centers on balancing print temperature, retraction, and infill to optimize PETG’s performance. A 230 °C hotend and 75 °C bed temperature ensure consistent extrusion and strong first layer adhesion. Retraction is set between 3–4 mm at 40 mm/s to minimize stringing, which is a common challenge with PETG, especially on small parts. Moderate infill and solid wall settings further enhance part strength and dimensional accuracy.
Print Temperatures: The hotend is set to 230 °C, which is optimal for Atomic Filament PETG, ensuring smooth extrusion and strong layer bonding. The bed is maintained at 75 °C to promote reliable adhesion and reduce warping.
Retraction: Retraction distance is tuned to 3–4 mm at 40 mm/s. This range is effective for PETG, helping to prevent stringing without causing jams or under-extrusion, especially important for small, detailed parts.
Infill and Walls: The profile uses a moderate infill density of around 40% and three solid walls. This combination provides a good balance between part strength and material efficiency, making it suitable for functional components.
Layer Height: The profile is set for fine detail with a 0.1 mm layer height, supporting high-resolution prints where surface finish and accuracy are priorities.
Bed Adhesion: A skirt is used for bed adhesion, which helps prime the nozzle and stabilize the first layers without excessive material use.
