Flexible PLA 1.75mm 3D Printer Filament

PLEASE NOTE: Sadly, we've stopped supplying filaments. After much consideration we've chosen to recommend the following supplier as an alternative.

Here's why:

  • Excellent dedication to customer service, quality & range of materials.
  • Very competitive pricing & UK based.
  • High reward customer loyalty plan.
  • FREE UK delivery on all orders.

  • 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.

    Probably my favourite filament, glad that I bought one of the last spools

    Unknowing of the impending end of rigid.ink filament sales, I bought another spool of natural colour flexible PLA to complement the black one I already have. It seems what I received will be one of the very last spools of this wonderful filament ever :(
    This has turned out one of my most favourite materials because it is easy to print with, and produces parts that can be both tough and flexible depending on how they were printed. With this filament it really is possible to print things that are nearly impossible to make without a 3D printer. I wear a smartwatch every day with a strap printed out of this stuff. I hope I'll be able to find something equivalent when these spools are used up.

    What a lovely material

    I finally got around to using the 10m sample of this Flexi PLA on my Hictop 3D printer.

    Before starting I gave the nozzle a run through with my Rigid Ink cleaning filament, just to make sure the black PLA was flushed out before using my nice yellow Flexi PLA filament.

    I read the information on the Rigid Ink website and set the nozzle temperature to 240 deg, the bed to 40 deg and print speed to 15mm/s, then hit start printing.

    Worked first time, No problems at all, the bed adhesion was great (I use a very thin wash of watered down PVA glue on my otherwise untreated aluminium bed. Only needs redoing after around 10 prints), and there was very little tendency to string.

    When finished, the part looks good and is very flexible. The part is a holder for a pet grooming brush and it needs to stretch slightly to allow the brush's handle to slip between the grips easily, which I'm glad to say it does.

    I'll be buying a roll of this stuff to print a few more flexible things with. Really like it.

    Flexible PLA 1.75mm 10m samples

    just had a new Flashforge Creator Pro (2018), so thought why not try a flexible PLA for making a couple of jewelry items turned out pretty damn well especially when you follow Rigid ink's guide , so much so i've just re-ordered some more 10m samples , well done keep up with the excellent products

    Great Prints

    This worked well on my Anycubic MegaS

    A great alternative to TPU

    I bought a few samples, one TPU, one flexible PLA and some other filament.
    On my Frankenstein printer it prints easily and quickly, nothing spectacular yet, a door wedge and a phone cable strain reliever. There isn't any notable odors, just like normal PLA. Definitely worth buying again, but larger than a sample pack, to save me finding an empty spool and winding on.
