Ultra-flexible material for soft support and impact absorption.
Bambu TPU 85A is designed for highly flexible parts that need softness, resilience and shock absorption. It is ideal for protective components, cushioning parts, soft-touch products and functional flexible applications.
Made for parts that need to bend, stretch and compress.
TPU 85A offers a softer feel and higher flexibility than harder TPU materials, making it suitable for soft contact parts, cushioning components and flexible designs that need comfortable deformation.
Designed to recover after repeated compression.
TPU 85A maintains strong elastic recovery, helping printed parts return to shape after bending, squeezing or impact. It is a good choice for bumpers, pads, protective covers and soft support parts.
Soft material that absorbs impact and vibration.
With its flexible structure and soft hardness, TPU 85A helps absorb vibration, impact and repeated contact, making it useful for protective gear, soft mounts and cushioning applications.

Printing Tips
TPU 85A requires highly precise printing conditions. Please follow the recommended settings before printing.
Blast drying oven: 70°C for 8 hours.
H2 Series: 90°C for 16 hours.
X Series: 90°C for 16 hours.
AMS HT: 75°C for 18 hours.
To avoid spool deformation that may prevent the spool from fitting into the dry box, please use a large dry box for TPU drying.
Increasing the maximum volumetric speed is not recommended. Keep the default speed during printing. All Bambu TPU 85A parameters are already pre-set. Turn off Flow Dynamics Calibration to match the fine-tuned setting.
Bambu TPU 85A does not support multi-material printing. To keep TPU prints clean and vibrant, avoid using dark-colored PLA as support material.
Do not press Unload when switching filaments, as this may cause uncut TPU residue to get stuck in the extruder. Heat the nozzle to 250°C, then control the extruder to retract and manually pull out the filament.
Pressing Unload to enable auto-retraction is allowed. Please maintain the filament cutter at the right inlet if printing TPU regularly, as it is more prone to wear out when printing TPU.
