TPU HF 95A — High-Flow Flexible Filament for Faster Printing

TPU HF 95A is a high-flow formulation of 95A shore hardness TPU, engineered to print significantly faster than standard TPU without sacrificing flexibility or durability. Where conventional TPU is typically limited to slow, cautious print speeds, TPU HF is formulated for improved melt flow — supporting speeds up to 150mm/s and dramatically cutting print time on larger flexible parts.

What Makes It High-Flow?

Standard TPU is notoriously slow to print — the material’s flexibility makes it prone to buckling and inconsistent extrusion at speed, especially on bowden setups. TPU HF addresses this with a modified formulation that maintains consistent melt flow at much higher volumetric rates, allowing faster print speeds while preserving the layer adhesion and surface quality that make TPU useful in the first place.

95A Hardness — The Flexible Sweet Spot

At 95A shore hardness, this filament bends and compresses under hand pressure while still holding its shape under normal loads — similar to a shopping cart wheel. It’s the most popular TPU hardness for 3D printing because it balances genuine flexibility with printability and durability.

Impact & Abrasion Resistant

TPU absorbs sudden impacts rather than cracking, and resists wear from repeated friction and contact far better than rigid filaments — making TPU HF well suited to parts that get knocked around, dropped, or rubbed against other surfaces repeatedly.

Print Settings

Nozzle temperature: 190–220°C
Bed temperature: 0–60°C
Print speed: 20–150 mm/s — significantly faster range than standard TPU
Retraction: reduce retraction distance and speed, or disable entirely to prevent jamming
Extruder: direct drive strongly recommended — bowden setups struggle with flexible filament at any speed, and high-flow TPU is no exception
Drying: 60–70°C for 6+ hours before printing — TPU is hygroscopic and wet filament causes bubbling and poor surface quality

Direct Drive vs Bowden

Direct Drive (Recommended)

The short filament path between the extruder gears and the hotend gives positive control over flexible filament, letting you actually take advantage of TPU HF’s higher speed capability. Bambu Lab X1/P1/A1, Creality K1, and most modern printers use direct drive.

Bowden (Challenging)

The long PTFE tube allows flexible filament to compress and buckle rather than feed cleanly. Even with a high-flow formulation, bowden setups should stay toward the lower end of the speed range.

Applications

Phone cases, bumpers, and protective covers produced faster
