  • ‘Enhanced’ PLAs have a bad reputation, some are no better than PLA, some perform worse in some conditions. We’ve taken a different approach: our ‘regular’ PLA is regarded as the strongest pure PLA in the industry, it’s hard to improve on the best. But sometimes you need something a little more durable. Enter our specially formulated PLA Plus. Prints like PLA, but with better durability.
  • Note: While not stronger or harder than our regular PLA, our PLA Plus is designed for applications where you need that enhanced durability, or even a little flex over standard PLA. This is a very tough PLA, it will never snap or shatter* – it will just eventually slowly deform. *Not tested in -0°C conditions.
  • Like a pearlescent sheen to your prints? Our PLA Plus colours have a beautiful sheen to them, which catches the light unlike any other filament. Check out the photos in the reviews below to see what we mean.
  • As with all filaments, our pure resin formula contains no nasty contaminants that lurk to block your nozzle at any moment. Your is also extruded to industry leading tight tolerances: this ensures consistent layers, giving uniform strength through your print and nicely finished layer lines. We guarantee 100% reliable printing. Every. Single. Time.
  • Any issues with your order or printing setup? We’ve got you covered. Our friendly, efficient and knowledgeable technical support team are on hand to get you back on track.
PLA Plus+ 1.75mm 3D Printer Filament


PLA Plus 1.75 Filament

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

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

What is PLA Plus?

PLA Plus is an enhanced version of our PLA that's less brittle and more durable. 

Please note: If you're simply looking for the strongest PLA on the market, you may be better suited to our 'regular' PLA here (though there's nothing 'regular' about our PLA).

PLA Plus is for applications where good vibration absorption and a lower fracture rate is needed.

*NOTE: Some printers do prefer lower temperatures for PLA Plus+ 200-210°C, bed temp 40°C. If your test print is looking a little too runny and the layers aren't cooling enough try lowering your temperatures.


We became so tired of the hordes of terrible quality PLA 3D printer filaments flooding the market, we decided to release our own. You need a PLA filament you can rely on, something that won't ever jam your head and produce flawless prints, every time.

Accurately represented colours, near-perfect tolerances and excellent raw material quality was our aim. It wasn't easy, but we're confident we've produced a 3D printer filament to be proud of. In fact, we'd be surprised if you found better.

Especially for this price.

Using the most technologically advanced equipment and the finest raw materials, we produce a consistent filament with a tolerance of just 0.03mm either side of the 1.75mm diameter we promise. We know it's good, we test it thoroughly with lasers.

Don't feel like committing to a whole KG roll?

No worries, we even sell lengths of our PLA filament in multiples of just 10 meters, allowing you to try out a range of colours at a fraction of the price. The colours you see in the images are the exact colour you'll receive. We may not have the biggest selection of colours (more coming soon!) but they won't disappoint. 

Sure the quality is amazing, but what about the service?

It's fashionable to say you give great service, but ours really is second to non. Seriously, not happy with your purchase in any way? Let us know, we'll bend over backwards to help you out. So why wait, order from just 10 meters or 1KG of today and start printing something amazing.

We even do free UK mainland delivery on orders over 65.00 GBP. 

Works with pretty much all filament based 3D printers, our spool size is - 20cm dia, 7cm width, 5.6cm dia spool hole.

Please note a different pigment is being used for the black from February 2017 onwards.

We do not hold Food Safety Certificates. Some of the raw materials used to produce our filaments are food safe accordingly to European regulations, but our filament in it's final form is not officially approved. Neither is the 3D printing process and all the components of 3D printers.

        Top quality stuff

        Printed brilliantly no issue

        Really poor layer adhesion

        Printing easily but no luck with layer adhesion, it just snaps, tried different temp with no luck (from 210 to 250C). Would not recommend at all.

        Hi Tom, Thank you for taking the time to leave your review, I'm sorry to hear you're having some issues with layer adhesion. I would like to help get this resolved for you if you're willing to try again? We have technical specialists on hand to help get your settings perfectly tuned in, please can you send me the print settings you have used and a photo of the failed print? Once we have your print spot on I'll see what I can do about replacing the filament you've lost so far. How does that sound? All the best, Jess

        Sadly, my experience with a 10M sample of black PLA+ was not a good one. Having had excellent results with 'normal' PLA I thought I would give the + a try. Using the recommended temperature settings and changing nothing else the filament fused itself to the bed. I destroyed the bed mat trying to remove the print. Rigid.Ink were helpful in suggesting what might be wrong, but I will stick with normal PLA for the moment.

        Hi Steve

        Thanks for taking the time to leave this review, I'm very sorry PLA Plus + didn't work out for you.

        I'm glad we were able to help with what the issues might be.

        If you did want to try again with PLA Plus+ we'll be happy to help!

        All the best,
        A Definite Plus!

        After several big jobs using Rigid Ink's PLA+ for the first time I find it gives consistent and excellent results with a nice finish and no adhesion, stringing or any other problems. I shall probably now order in RI PLA+ in preference to normal PLA in the future. I have been 3D printing for some few years now; my current printer is a Prusa i3Mk2.

        Tough as old boots

        Great filament and way more durable than normal PLA. The sweets were nice as well.
