SUNLU TPU-95A Blue 1.75mm 1kg 3D Printer Filament

Recommended print temperatures are 200-220°C for the nozzle and 50-60°C for the bed. Print at slower speeds (20-40mm/s) to ensure optimal extrusion and layer adhesion. Minimal retraction (0.5-1mm at 20-30mm/s) or disabling it can help avoid clogs and improve print quality with flexible filaments.

To minimize stringing, ensure your filament is dry and stored properly. Experiment with minimal retraction settings, typically 0.5-1mm retraction distance at 20-30mm/s speed, or consider disabling retraction for very flexible designs. Slightly lowering your nozzle temperature within the recommended range can also help reduce ooze.

For reliable bed adhesion with TPU-95A, a heated bed set to 50-60°C is crucial. Using a PEI sheet, Kapton tape, or a layer of glue stick on a glass bed can significantly improve first layer grip. This helps prevent warping and ensures the base of your flexible print adheres securely throughout the process.

While durable, flexible filaments like TPU-95A can be challenging for highly intricate, hollow, or high-overhanging structures. Their inherent flexibility during cooling can lead to deformation or difficulty in bridge execution. Simple, solid designs generally yield the best results, minimizing printing difficulties and enhancing overall part strength.

Yes, like most flexible filaments, TPU is hygroscopic and absorbs moisture from the air, which can lead to poor print quality, stringing, and bubbling. It's recommended to dry TPU filament at 55-65°C for 6-8 hours before printing, especially if it has been exposed to humidity, to ensure optimal performance.
