TPU HF 95A Transparent — High-Flow Clear Flexible Filament

TPU HF 95A Transparent combines a high-flow formulation with a clear, translucent finish — flexible, fast-printing, and genuinely see-through. Where standard TPU is limited to slow, cautious print speeds, TPU HF is engineered for improved melt flow, supporting speeds up to 150mm/s while retaining the layer adhesion and clarity that make transparent flexible parts possible.

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 without sacrificing surface quality or transparency.

Why Transparent TPU HF?

The clear, translucent finish adds a visual dimension that solid-colour TPU can’t match, while the high-flow formulation means you’re not sacrificing print speed to get it. Light passes through the printed walls, making it useful for LED light diffusers and covers, protective cases where you want to see the contents, clear flexible windows in enclosures, translucent phone cases and covers, light pipes and indicator windows, and decorative prints with an ice-like or glass-like appearance.

Print with 100% infill and minimal walls for maximum transparency. Thinner walls and fewer layers produce the clearest results.

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.

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 with a clear finish
Light pipes, diffusers, and LED covers
Clear flexible windows in enclosures
Gaskets, seals, and vibration dampeners
Wearable items — watch straps, bracelets
Batch production of clear flexible parts where print time matters
Any application needing transparent flexibility with a faster turnaround
