This profile is designed for printing with SunLu TPU 95A flexible filament using curaSlicer. It is tailored for makers and engineers working with direct-drive extruders who need reliable, high-quality results with flexible materials. The profile prioritizes print quality, strength, and consistent extrusion, minimizing the risk of clogs and print failures common with TPU.
Flexible filaments like TPU require careful tuning to avoid issues such as stringing, under-extrusion, or jams. This profile uses low print speeds and minimal retraction, which are essential for smooth feeding of soft filament through direct-drive systems. The settings are optimized to balance flexibility, layer adhesion, and dimensional accuracy, ensuring dependable results for demanding applications.
Low Print Speed: The profile uses a slow print speed to prevent filament buckling and ensure smooth extrusion, which is critical for flexible materials.
Minimal Retraction: Retraction is set very low to avoid pulling soft filament back into the extruder, reducing the risk of jams and clogs.
Direct-Drive Compatibility: The settings are specifically tuned for direct-drive extruders, which handle flexible filaments more reliably than Bowden setups.
Moderate Print Temperatures: The nozzle and bed temperatures are set to promote good layer adhesion without overheating the filament, supporting both print quality and part strength.
Brim Adhesion: A brim is used to improve bed adhesion and reduce the risk of warping or lifting during the print.
