3D Printer Filament TPU High Speed 1.75 mm Clear 1 kg, eSun TPU-HS175T1P1

eSun TPU High Speed 1.75 mm Clear filament is a thermoplastic polyurethane filament designed for flexible, impact-resistant 3D prints. Supplied on a 1 kg spool, this clear TPU formulation balances elasticity and strength to produce wearable parts, protective covers, gaskets and functional prototypes. The filament is intended for printers that accept 1.75 mm thermoplastic filaments and is optimized for higher printing speeds compared with standard TPU grades while retaining good layer adhesion and surface finish.

Advantages

This TPU High Speed filament offers a combination of rapid printing capability and reliable flexibility. Its clear appearance enables semi-transparent parts and easier color matching when overprinting or dyeing. The material demonstrates high elasticity, good abrasion and impact resistance, and consistent diameter that supports stable extrusion and reduced clogging risk. The formulation is tuned to print at faster feed rates while maintaining dimensional stability and layer bonding typical for TPU elastomers.

Suitable for

• Wearable parts and flexible accessories (straps, bands, wristbands)
• Phone cases and protective covers
• Seals, gaskets and vibration-damping components
• Flexible functional prototypes and moving joints
• Decorative semi-transparent elements and overmolded features

Key specifications

• Material type: Thermoplastic polyurethane (TPU), high-speed formulation
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg of filament
• Color / finish: Clear / semi-transparent
• Mechanical properties: Elastic and impact-resistant with good abrasion resistance
• Compatibility: Designed for FDM/FFF printers that accept 1.75 mm filament

How to use

Load the 1.75 mm filament into the printer following the manufacturer’s filament loading procedure. Use print settings appropriate for flexible TPU: moderate nozzle temperature and reduced retraction distances to avoid jamming; adjust print speed to benefit from the high-speed formulation while monitoring extrusion stability. Ensure a direct-drive or compatible feeder system to maintain consistent filament control. Print with a build surface that promotes adhesion for TPU and consider a brim or skirt for small parts to improve first-layer stability. Allow printed parts to cool before removing to prevent deformation.

Usage recommendations

Recommended starting settings: nozzle temperature in the typical TPU range for your machine, moderate bed temperature if required, print speed adjusted upward from standard TPU settings but tested incrementally, low retraction distance, and secure filament path (direct drive preferred). Store the spool in a dry environment to prevent moisture absorption which can affect print quality.
