We know TPU's
every quirk.
20 years on one material, from raw resin to formulation: hardness, rebound, weather resistance — tuned and controlled to spec.
Real printed parts in motion — production-ready out of the printer.
Fast and bouncy, in every hardness.
From 75A to 95A, each series has its own dedicated high-speed and high-rebound formula.
Rigid filaments print “shape”, flexible TPU prints “function”
Soft, resilient, wear-resistant, impact-absorbing, skin-friendly — when a part needs to bend, compress or be worn, TPU is the only answer.

柔Ultimate Softness
300–500% elongation — 50–80× that of PLA. Bends, wraps and conforms.
弹High Rebound
Springs back under repeated compression — ideal for soles, cushions and seals.
韧Tough & Impact-Resistant
Tens of times more abrasion-resistant than PLA, absorbs impact without shattering.
亲Skin-Friendly
Soft and gentle on skin — perfect for wearables and rehabilitation aids.
耐Oil & Water Resistant
Resists oil, water and weathering — reliable for industrial seals and outdoor parts.
Health & EnvironmentSafer

Low Odor
Nearly odorless printing — safe for workshops, offices and kids' products.
Low Dust & VOC
Emits far less than ABS or resin — print comfortably without forced ventilation.
Recyclable
Thermoplastic — waste can be re-pelletized and recycled to cut long-term cost.
Antibacterial
Antibacterial additives inhibit bacterial growth — ideal for straps, insoles, braces and other long-wear skin-contact items.
* Odor / dust / recyclability / antibacterial properties are qualitative descriptions; performance figures are subject to the final test report.
TPU prints as easy as PLA.
Stringing, nozzle knock and clogging — the reasons people avoided TPU — are now solved, so any standard printer gets a clean first print.
Print Faster
We solved stringing and nozzle knock to make TPU run fast. 220 mm/s high-speed printing with 70% less stringing — no more waiting for a soft result.
Print Better
40% stronger interlayer bonding — every layer sticks, every surface is clean, every bit of elasticity is real. Speed and quality, no longer a trade-off.
Footwear first, far beyond
One material, endless possibilities. Whatever needs to bend, cushion, seal or flex — TPU is the answer.

Trusted by teams like yours
From footwear studios to protective gear manufacturers — teams choose TOPFOX for consistent, production-ready TPU.
Serving industries worldwide
20 years, one material
From base resin to filament, from formula to process — one focus: make TPU print fast and print well.
20 years, one material
For 20 years we've worked with a single material — TPU. From synthesis and formulation to extrusion, we've gone deep. Soft, skin-friendly, high-rebound, wear-resistant: we know how good it is, and how hard it is to get right.
A silent bias
3D printing defaults to hard, cold PLA and ABS. The things we actually wear should be soft — yet most people avoid TPU because it's 'slow to print, stringy, and won't stick'.
Taking on the hard part
20 years of accumulation, for this moment. Make TPU print fast (efficient) and make every layer bond firmly (high quality) — that's how the TOPFOX five-hardness series came to be.
In a world chasing faster, stronger, harder — we perfect soft.
Not just filament — help you build better shoes
Shore selector · tread library · cushioning data · last database — four tools, free to use.
Grow the TPU filament market together
Factory-direct pricing · protected territories · full testing docs · stable supply — we're recruiting distributors, agents and OEM partners worldwide.
In a rigid world,
we choose soft.
Not just a spool. A joyful printing experience.
