Printing with Bambu TPU 95A HF: Recommended Settings

Using Bambu TPU 95A HF filament for 3D printing requires critical adjustments for best results. Each setting can greatly impact the final product.

Nozzle Temperature: 220–240°C

A nozzle temperature between 220 and 240°C works best. I found that 230°C gives a good balance between speed and detail. Bambu Lab recommends a hardened steel or stainless steel nozzle for optimal results with this TPU filament Bambu.

Bed Temperature: 30–35°C with Glue

A bed temperature from 30 to 35°C helps the filament adhere properly. Applying a thin layer of glue increases bed adhesion, reducing warping issues. Bambu Lab recommends using the Smooth PEI Plate or Textured PEI Plate for best adhesion with TPU 95A HF.

Printing Speed: Up to 200 mm/s

The filament supports speeds up to 200 mm/s, enabling faster production without sacrificing quality. I achieved great results at 180 mm/s. For maximum reliability, start at around 100–150 mm/s and gradually increase.

Pre-Print Preparation

Proper preparation can save time and improve print quality. Clean the bed to remove any dust or leftover material, and ensure your extruder is free from clogs when switching to Bambu TPU filament. Adding a brim is recommended to reduce warping and improve first-layer adhesion.

Humidity Control and Filament Storage

Storing Bambu TPU 95A HF filament in a dry place is essential to prevent humidity from affecting print quality. TPU 95A HF is highly sensitive to moisture — perhaps more so than many other filaments. Use a sealed container with desiccant packs. Humid filament can lead to bubbles, poor layer adhesion, and stringy prints. Bambu Lab recommends drying the filament at 70°C for 8 hours before printing. For X1 Series owners, the heatbed at 80–90°C for 12 hours is an alternative drying method.

Troubleshooting Common TPU 95A HF Print Issues

Even with optimal settings, you may encounter issues when printing with Bambu TPU filament. Stringing is common with TPU — reduce it by enabling retraction and lowering nozzle temperature by 5°C. For poor bed adhesion, apply glue stick and reduce initial layer speed. Clogging can occur as flexible TPU buckles in Bowden tubes, though Bambu Lab’s direct drive extruder minimizes this. Under-extrusion usually results from moisture — always dry your TPU 95A HF spool before printing.
