  • 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

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. 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.

Is it possible to be in love with a printer filament? Yep, it really is.

Until now I've always avoided flexible filaments as they're supposed to be difficult to print on a Bowden extruder machine but this flexible PLA is super easy. The print sticks so well that I've had to go back to blue painter's tape simply so I can get it off the bed without damage. There's no warping of course as it's a flexible material.
To be fair I have had to slow everything down and impose a minimum layer time of 120 seconds as the filament does seem to need time to properly cool between layers so bed time tonight looks like it's going to be 1am but the upside is that the print has great detail.
The filament is incredibly versatile, design the part with good thick perimeters and lots of infill and it's solid like normal PLA but in thin layers it's transparent and completely flexible. A little experimentation and it's been possible to introduce cushioning into parts so I now have some replacement cupboard feet which are solid and sturdy yet the lower 10mm compresses slightly and takes up any unevenness in the floor surface.
Rigid Ink seem to care about customers, an email as soon as I placed the order with advice on settings was really helpful. I'm not so sure about the card that came with the filament though as it appears to give the wrong extruder temperature range for flexible PLA - 240-250C - er, really? I'm getting great results at 170C/180C.

Why did I wait so long before trying this super filament?

Hi Calvin,

Thanks for taking the time to write this honest and positive review.

I'm glad you like our Flexible PLA and would love to see some of your projects!

Regarding the temperature, our recommending settings are correct on the card, but it is true that Flexible PLA has wide temperature range.

170C seems too low for any filament, so I think your thermometer is reading it a little bit wrong.

But as you know, 3D printing is one big experiment so if you found your ideal temperature for your set up then stick to it :)

All the best
Monica

Prints well, very flexible and tough

This prints well on my Wanhao i3 v2 with a slightly modified extruder (see Thingiverse ID 1340811). I print it at 250C with a 40C bed. It prints best going slowly at around 20mm/s, but for some simple parts, you can increase the speed up to around 40mm/s. The Benchy in the photo was printed with an initial speed of 40mm/s, but I slowed it down to 20mm/s once it got to the roof.

The parts are very tough and flexible, it's surprisingly difficult to break them. They can be twisted around without without de-laminating.

Awesome semi-flex, but the settings took some time

Honestly, I love this stuff, at first I was hesitant to buy a full kilo, so I bought a sample of this stuff, and before that sample was over, I bought the full kilogram.

It's not elastic, but it is flexible, but keep in mind that it's flexibility heavily depends on the top,bottom and perimeter numbers, and to a lesser extent the infill. I'm using this for a watch strap and some bracelets for kids, and potentially shock absorbing feet for my printer.

On my printer, 240 celsius hot-end, 35 bed (though tbh I have turned it off before with little to no ramifications) no retraction, 115% extrusion multiplier and 15mm/s speed. Oh, and this is on a bowden printer, I'm sure you could print substantially faster on a direct drive printer.

Soft, strong and nothing like andrex!

I did have to slow down the print head speeds but otherwise as easy to print with as pla.
