  • 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.
Flexible PLA 1.75mm 3D Printer Filament

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
Density: 1.25-1.27g/cc

Good but a little hard to start

I printed a few things with it and still got quite a bit. But the dice I printed wasn't very good but it dose roll better than a hard pla dice.

Hi Deacon,

Thanks for taking the time to leave this positive review and I'm glad you like your Flexible PLA.

We have our technical specialists on hand to help not only when things go wrong but also to get your prints perfectly tuned in, It's no coincidence that our customers get some of the nicest looking prints out there.

Please get in touch if you're not getting the results you want and I can help you get your print looking perfect.

Keep up the great work!

All the best,
Jess

Ideal for tires!

I've been looking for something flexible for toy tires, but not too flexible as I want it to hold it shape well when played with. Plus my printer has a Bowden extruder and isn't ideal for flexible stuff.
This printed first time perfectly, it's just the right kind of flexible, tough but will give . Ideal for pushing a tire onto a hub and being sure it'll stay on tight!

Worked first time - no waste!

I wanted to try some flexible filament to make an end-stop for a ladder, so I thought I'd try a sample 10m. However, I ended up making three rubber "kilner" jar type seals for some garden lights! Each one took 3.01 metres. I loaded up the filament, hit the "go" button and boom, excellent print first time with absolutely no wastage on all three. And, I had 2 metres left! Very little stringing and good bed adhesion. I used masking tape with a wipe of Pritt Stick.

It seems a bit pricey but it's definitely good quality and amazingly enough, works with the settings recommended by Rigid Ink - something other makes seem to always get wrong.

It's on my buy-it list.

Hi Pete,

Thanks for taking the time to write this positive review!

It's great to hear you've printed a practical part from our Flexible PLA and I'm glad it's all working well for you.

Keep up your great work

All the best

Wow

This flexible pla bright pink was easy to use i printed at 15mms on anet a8 with titan aero kit on a 0.4 nozzle at 240°c and a 55°c bed on glass bed the first print i forgot to turn of retraction and got a clog 86%thru the print but the second test print came out flawless the colour is bright and fibrant love this filament

Amazing stuff

I bought my flexible PLA on a whim as part of an order - I didn't really have a need for flexible filament.
I was very impressed with how well it printed and how much smooth the resulting prints are - there are no hardly any of the usual patterns in the layers caused by micro-changes in stepper torque. I believe the fact that the filament is flexible and more compressible helps to average out the mechanical forces.
My first test was a simple ring, which when finished felt very much like a medium-hard rubber seal that might be used in plumbing. That set off some light bulbs, as I needed to make a seal for a vacuum project. Tried it for that and it worked like a charm. I also printed a sort of a simple spring/damper that I needed. This stuff would be ideal for making suspension parts for models or anything that needs a bit of give. It's also incredibly strong, my first ring has a 3mm diameter and I can't break it by hand.
Had no problem printing at 50mm/s at the stock temperature. I would recommend backing off the cooling fan rates to make sure it doesn't cool to fast as I did find my earlier prints could delaminate into strands (rather than full layers).
I could not print it until I had upgraded my hot end, you need the feed tube right against the drive hob to mitigate bending.
Will certainly buy more but I don't expect to use the current spool quickly as it's not a common use filament.
