Need flexibility along with easy printability? Then you need rigid.ink 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.

rigid.ink 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 rigid.ink 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 rigid.ink 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. rigid.ink 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, rigid.ink 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 rigid.ink TPU is capable of producing prints as clean and detailed as objects made from PLA or ABS. Finally, the density of Ninjaflex and rigid.ink TPU are nearly identical, with 1.20g/cm3 for NinjaFlex (and similar TPE filaments) and 1.21g/cm3 for rigid.ink TPU.

Worked first time on Ultimaker 2+

I was trying to find a flexible material that would work in an Ultimaker. I've tried a flex-pla before but while it did work the resulting print wasn't very flexy. I was really impressed with this TPU, it worked straight away with the recommended settings and the resulting print was really quite rubbery.

Hi Andrew, This octopus looks awesome! I'm so glad you liked the TPU. Thank you for your positive review and for sharing these photos. It's great to see the flexibility in action there. All the best, Rosie

2.85mm TPU blue

Colour exactly as I expected from website. Quick delivery, good packaging. Filament prints as well as my printer allows. When I finish tweaking settings I'm sure my prints will look great. Print temperatures and information supplied on the website and on packaging are all spot on.

Very nice printing, even with a bowden!

Ordered a sample and I'm finding new love for flexible filaments with this TPU. I have an Ultimaker and as such have difficulty with some flexible filaments due to the compression within the Bowden tube. This filament, however, has just enough stiffness to overcome that and the prints I've made have been near perfect. It does require a little bit of TLC, but using the same settings that Ultimaker recommend for their TPU 95 were brilliant. I will certainly be looking to buy a full roll once available.
