## Summary description

TPU 90A flexible filament, 1.75 mm diameter, 1 kg spool suitable for FDM 3D printers. Provides high elasticity and abrasion resistance with Shore hardness ~90A, designed for printing elastic parts such as gaskets, seals, wearable items, and shock-absorbing components. Compatible with direct-drive and some Bowden setups; requires tuned print temperature and slower print speed for best results.

## Long description

TPU 90A 1.75 mm 1 kg filament from BambuLab is a thermoplastic polyurethane designed for FDM 3D printing of flexible, durable parts. With a Shore hardness around 90A and 1.75 mm diameter on a 1 kg spool, this filament balances elasticity and abrasion resistance for functional prints. It is formulated to work with a range of printers including direct-drive systems and many Bowden setups when settings are adjusted. Typical applications include gaskets, seals, wearable prototypes, and shock-absorbing components where resilience and surface durability are required.
Advantages
This TPU filament provides high elasticity combined with good abrasion resistance, enabling parts that recover shape after deformation and withstand repeated use. The consistent 1.75 mm diameter and carefully controlled formulation reduce clogging and extrusion irregularities when printing at appropriate temperatures and speeds. Compatibility with both direct-drive extruders and many Bowden configurations gives flexibility across printer types, while the 1 kg spool supports medium-length production runs or multiple prototypes without frequent spool changes.
Suitable for
 Gaskets and sealing elements
 Wearable prototypes and flexible accessories
 Shock absorbers and vibration-damping parts
 Flexible hinges and snap-fit components
 Functional prototypes requiring abrasion resistance
Key specifications
 Material: Thermoplastic polyurethane (TPU)
 Shore hardness: approximately 90A
 Diameter: 1.75 mm
 Spool weight: 1 kg
 Color: as supplied by manufacturer
 Intended printing technology: FDM/FFF
How to use
Load the 1.75 mm TPU filament into your printer according to the manufacturer's instructions for flexible materials. Use a direct-drive extruder when possible; if using a Bowden setup, ensure the filament path is as constrained and supported as feasible to reduce buckling. Set print temperature and speed based on the printer and hotend compatibility—start with the manufacturer's recommended temperature range for TPU and reduce print speed compared to rigid filaments. Enable retraction settings optimized for flexible filament or disable retraction if stringing persists. Use a build surface that promotes adhesion for TPU, such as PEI or blue painter's tape, and consider a brim for small parts to improve bed hold.
Usage recommendations
For reliable results, print at slower speeds and fine-tune temperature and retraction settings. Store the spool in a dry environment or sealed bag with desiccant to prevent moisture uptake, which can affect print quality. Test small calibration prints to determine the optimal settings for your specific printer and application.
