  • While other flexible filaments can be tricky to print, producing stringy prints with poor layer adhesion, was developed with this in mind. We’ve created something that prints nicer, and just happens to be incredibly tough and durable.
  • Smooth feeding and printing, our low friction 94A shore hardness TPU filament negates the typical headaches with printing flexibles. Plug in the settings (prints from 210°C) and enjoy our famous ‘set and forget’ reliability.
  • Just how durable? Well, with a massive elongation to break of 500% and unparalleled layer adhesion you can produce practical end-use parts that won’t let you down.
  • With our industry leading tight tolerances, you get super smooth and consistent layer lines, leaving a beautiful finish. And there’s no stringing thanks to our heat stable viscosity formula. With TPU you get 100% printing reliability.
  • Any problems, on anything to do with your order or your prints and you can interrogate our friendly, efficient and knowledgeable technical customer support. We’re here for you. And we won’t let you down, ever.

The names have changed but the colours have not, so you can continue to order the same vibrant colours you have previously.

Need flexibility along with easy printability? Then you need TPU filament.

TPU (or thermoplastic polyurethane) is a remarkably flexible, remarkably durable 3d printing filament that’s also very easy to use.

Some flexible filaments, like TPE, can be difficult to work with. The relative softness of the material, which gives it the desired flexibility, can also mean that the average extruder will have a hard time handling it. Instead of feeding smoothly into the hot end, the flexibility of these filaments cause them to bend and knot up in the excess spaces in the print head. TPU solves this problem by being slightly harder than other flexible filaments. It’s Shore Hardness rating of 94A means that the extruder mechanism has fewer problems handling TPU. Material bending is reduced and this means less knotting and less headaches for you.

Even though TPU is a bit more rigid than other flexible filaments, it’s very similar to those filaments when it comes to elasticity and other mechanical properties. This means that TPU can be used to produce a wide variety of objects that need to bend or flex during use. Typically, this includes things like belts, springs, phone cases and vibration dampening parts. TPU also exhibits a high degree of abrasion resistance along with a resistance to oils, greases and a variety of solvents – making it more favorable in industry applications.

Like Ninjaflex and similar TPE filaments, TPU is comprised of non-toxic raw materials. It also has excellent layer to layer adhesion. This results in very durable end-use prints that also exhibit a high level of quality. Users have found that TPU is capable of producing prints as clean and detailed as objects made from PLA or ABS. Finally, the density of Ninjaflex and TPU are nearly identical, with 1.20g/cm3 for NinjaFlex (and similar TPE filaments) and 1.21g/cm3 for TPU. Due to the nature of Flexible filament, the diameter tolerances are +/- 0.05mm compared to rigid filament at +/- 0.03mm.

My first TPU print

I have so far had a great experience with this tpu filament after hearing some bad stories of other filaments and the perils of flexible filament printing. This filament has so far been so easy to use and can only get better from here as I hone my printer settings and my own technique.
A very pleased and repeat customer.

TPU filament

The filament was good, just wanted it for some tyres for a rc plane,
Set my printer up with slower settings,
Thanks Richard.

TPU 1.75mm Black

Superb results.
Home built Cartesian using 2040 V Slot, hiwin linear rails, e3d titan aero, running marlin 1.1.8
220 nozzle, 70 bed, 15mm/s.
Can control how hard or soft the part is by varying the infill percentage.
It is a bit expensive, but worth every penny once you see the results

Hi David,

Thanks for sharing your settings with us!

I'm glad you like our TPU and will be looking forward to see some photos of your projects :)

All the best
Superb filament.

It prints like butter, sticks well to the bed, has superb colour, layer adhesion and strength - and I'm not just saying this from hand testing - this filament is so durable, consistant and reliable I use it to make functional engine and suspension bushes for race and rally cars!
If you want to make detailed models that's no issue either, unlike a lot of other TPU's it's great at overhangs and fine detail even when printing at high temperatures (250-260c).

Hi There,

Thanks for taking the time to write a review and for sharing the photos.

Your prints look fantastic, keep up the great work!

All the best

Tried it out for the first time and it prints like a dream on my mk2s no problem
