This profile is designed for printing flexible gaskets, grips, and seals using TPU filament in orcaSlicer. It is ideal for makers and engineers who need reliable, functional flexible parts with good compression resistance and consistent quality. The settings focus on balancing flexibility, strength, and print reliability, making it suitable for demanding applications where performance matters.
The profile is tuned specifically for TPU’s flexible nature. Slow perimeter speeds help prevent stringing and ensure clean, accurate outlines. Zero retraction is used to avoid filament jams and under-extrusion, which are common issues with flexible materials. Moderate infill density provides enough structure for compression resistance while maintaining the flexibility needed for gaskets and grips. A brim is used to improve bed adhesion and reduce the risk of warping or lifting during printing.
Slow Print Speeds: Perimeter speeds are kept low (22–28 mm/s) to ensure precise extrusion and minimize defects, which is critical for flexible filaments like TPU.
Zero Retraction: Retraction is disabled to prevent filament stretching and clogging, which can cause inconsistent extrusion with TPU.
Moderate Infill: Around 25% infill strikes a balance between flexibility and structural integrity, making parts compressible yet durable.
Three Solid Walls: Using three wall loops increases part strength and helps prevent leaks in gaskets and seals.
Brim Adhesion: A brim is added to improve first-layer adhesion, reducing the risk of warping or detachment during printing.
