This profile is designed for printing flexible phone cases and grips using TPU 95A filament in curaSlicer. It is ideal for makers and engineers seeking reliable, high-quality results with flexible materials. The settings focus on achieving a balance of flexibility, strength, and consistent print performance, especially for medium-sized parts like phone covers.
The profile is tuned specifically for TPU 95A, a flexible filament that requires careful handling to avoid issues like skipping or stringing. By using slow print speeds, disabling retraction, and applying low cooling, the profile minimizes the risk of filament jams and ensures smooth extrusion. The use of single wall exteriors enhances the flexibility of the finished part, making it well-suited for phone cases that need to bend and absorb impacts.
Slow Print Speeds: Printing at reduced speeds (as low as 12-20 mm/s for walls and initial layers) helps prevent filament skipping and ensures accurate layer placement, which is crucial for flexible materials.
Zero Retraction: Retraction is disabled to avoid filament jams and under-extrusion, which are common with TPU. This setting is especially important for direct drive extruders.
Low Cooling: The cooling fan is set to a low speed (20-30%) to maintain layer adhesion and prevent warping, while still allowing the print to solidify enough for overhangs.
Single Wall Exterior: Using two standard walls and a concentric pattern maximizes flexibility while maintaining enough strength for daily use as a phone case.
Brim Adhesion: A brim is used to improve bed adhesion, reducing the risk of warping or lifting during the print.
