  • Tried other flexible filaments? They can be tricky to print. That’s why we developed our Flexible PLA filament with ease of printing in mind. Our secret? We’ve made a flexible, but slightly less elastic material with very low friction. This gets around the ‘pushing string’ issue that plagues most extruders to finally give you an easy and predictable printing experience with flexible materials.
  • While not technically a PLA, but it is a similar natural based Biopolymer. This means that like PLA, it will naturally degrade over a long time frame, in the correct conditions.
  • WARNING: Extremely good bed adhesion, so if you’re using something fancy like PEI sheet or Buildtak, you’ll just want to put some blue tape or glue stick layer over it to save any grief removing the print from the bed. The good news is that this also means excellent layer-to-layer adhesion, leaving you with very durable prints.
  • Our flexible or soft PLA gives you ‘rubber like’ parts, without the high elongation of materials like TPU. Print Flexi PLA thin and you’ll get a very flexible part, print it thick and you’ll get a reasonably stiff model with a lot of flex to it.
  • Like all rigid.ink filaments, our Flexible PLA is contaminant free and extruded to industry leading tolerances. This means consistently strong prints, with an excellent layer finish, every single time. We guarantee 100% reliable printing. And any issues? Our world-renowned technical support team is on hand to get you back on track.

Description

Flexible PLA 1.75 Filament

Please note the following colour name changes (18.07.18):
Fire Red = Flash Red
Light Blue = Bright Blue
Light Green = Lime Green

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

This versatile material is a Biopolymer flexible filament. OK, so it’s not strictly a PLA by definition, but it is all-natural filament, similar in properties to PLA (such as biodegradable and easy to work with).

Our flexi PLA is versatile; you can print it thick walled, or higher infill for a stiffer, extremely durable part. Or you can print the walls thinner, with much lower infill to create a very flexible, soft structure. See the wheel below.

How easy is it to print with? Compared with other flexible filaments, very. The wheel above was actually printed on an Ultimaker 2. For those not already impressed, that printer uses a rear feeding mechanism, which when presented with typical flexi filaments can cause it to jam as it’s like ‘pushing string’ and coils up. What makes ours different? It’s low friction, which means our flexible pla will feed through nicely and print correctly – on all machines.

With our special blend of resin, you can be confident of excellent layer bonding, resulting in consistent long-lasting prints. With no stringing or blobbing, you’ll also get a detailed layer finish you can be proud of.

This soft pla won’t stretch much though, so it’s also ideal for printing pulley belts, or tank tracks etc. A truly excellent all-rounder for flexible applications, and a great starting material to get to grips with flexible prints before moving onto other materials, such as our TPU (similar to Ninjaflex and other Polyurethane based filaments). The Shore hardness is 55D.

As with all rigid.ink filaments, you can be confident of excellent printing reliability thanks to our super-tight tolerances and pure raw materials. Due to the nature of Flexible filament, the diameter tolerances are +/- 0.05mm compared to rigid filament at +/- 0.03mm. There won’t be any particles lurking to block your extruder, or contaminants that can weaken your prints.

rigid.ink soft, flexible PLA will perform time after time. And if it doesn’t, or you simply change your mind – we offer one of the best guarantees in the business. 60-days to return or exchange, no questions & no hassle. We’re really committed to making you happy with your prints.

3D printing can be problematic enough, without you worrying about filament issues.

Not confident to purchase a 1KG roll? We’ve got nothing to hide, so order a 10m sample today to see for yourself.

Settings


Guide Settings
Printing Temperature: 240°C
Bed Temperature: 30-60°C
Bed Adhesion: Glue-stick, 3DLAC, Vinyl hairspray. Increase the air-gap between nozzle for the first layer and the bed. Avoid FR4, PEI and BuildTak.
Print Speed: 15mm/s (higher speeds may need slightly hotter printing temp, up to 245°C, slower speeds may need slightly lower printing temp, around 230-235°C)
Cooling Fans: 100% after layer 1
Retraction: Increase more for flexible materials

Good ventilation is essential and do not leave print unattended.

Information

Flexi PLA on a QiDi

I found the flexi PLA an awful lot easier to use than TPU using the standard QiDi x-pro. The TPU tended to have more feed problems although with both using the lighter 300g spool made a big difference.
I love Rigidink products.

Excellent "rigid" flexible filament

I bought this (natural white) flexible filament as it seemed to be one of the more rigid ones out there and I only needed a bit of flex in my project. And wow, I have to admit that I am impressed! Extreme layer-bonding and good flex (shore hardness 55D seems to be right). I printed on a Prusa i3 MK3 (direct drive) with no modifications at 30 mm/s, 3 mm retraction and only a tiny bit of stinging which was easy to clean up.

I seriously consider to use this for the major parts of my project as the stiffness (and corresponding brittle nature) of PLA and PETG is really not that useful for most projects. And the toughness of this filament means that the wall thickness (and thus total mass and used filament) can probably be reduced significantly as compared to PLA/PETG versions of the same printed objects.

I expect that bridging and overhangs might be more difficult with this filament although a have not tested it.

Flexible PLA - prints and performs great

I bought flexible PLA to make a number of adapters for dust extraction in our Men's Shed workshop. Prints very well at the recommended settings and will stretch a little if too tight by dipping in hot water. Great product, very flexible. Now looking for other applications. I am thinking of making an emergency drive band for my mini lathe. Unfortunately I didn't take any photos but will add some later.

blue TPU

Thanks for your inquiry. Am still evaluating the blue TPU but from my prints so far I am finding that the AMBIENT temperature has a noticeable effect on surface print quality. On a warm day (ambient temp in the mid to high 20s) surface quality is much better than at lower ambient temps especially if the item being printed is more than 2cm tall. At low ambient temps the first 2cm print well (as as the temp of the item is close to the heated bed temp) but as the print's height increases the print surface gets rougher. To overcome this problem I am constructing a cabinet for the printer to keep the print area at a constant ambient temp of around 25 to 30 degrees C. I'll keep you informed in due course of my findings once the cabinet has been completed. Am pretty sure this will solve the problem. The TPU prints well on my Creality at 212 deg C.
This cabinet should also benefit PLA printing now that the colder weather is here. Regards Peter Martin

Hi Peter,

Thanks for leaving this review and letting us know how you got on with your PLA. Sorry that you've had rough finishes on a few of your prints.

It sounds like you've got a promising solution though, good idea to build a surrounding cabinet.

Do let us know how that works out for you and if you have any comments or queries, get in touch again.

All the best,
Rosie
