  • While ABS is strong and excellent for end-use parts, in prolonged outdoor use it can yellow and crack over time. This is because UV light often degrades many polymers. Enter: ASA filament. Our UV resistant, and slightly even more durable version of ABS.
  • With improved weather resistance and excellent chemical resistance, ASA is the ideal material of choice for casings or outside prints. Our tested formula, free from contaminants means you’ll get exceptional layer to layer adhesion giving excellent finished part strength.
  • Our industry leading tight tolerances of just 0.03mm+/- the stated 1.75mm or 2.85mm diameter give consistent layer lines, every time. This means perfect layer lines, leading to an excellent all-round surface finish. It’s just one of the ways we can guarantee 100% printing reliability.
  • The last thing you need is a 15 hour print failing in the last 30 minutes. It wastes filament, your time and your money. But worse, it lets your customer down. We understand, and we know you need to use a filament you can put your trust in.
  • It’s not just our unrivalled filament quality and relaxed guarantee that you’ll be impressed by. We understand you need the customer service to back you up. That’s why our friendly, efficient and knowledgeable technical support team is always on hand should any problems arise.
ASA 3D Printer Filament


ASA 1.75mm & 2.85mm Filament

Please note: Previously available 2.85mm colours were discontinued 24.08.18. If you wish to order any of these colours please contact to discuss options.

Need a weather resistant, UV-stable version of ABS? Our ASA filament is the answer (full name: Acrylonitrile Styrene Acrylate). It has excellent strength, with a great all-round weather and chemical resistance. This is fast becoming a popular 3d printing material for outdoor applications.

Whether you’re printing for business, education or just making your next trinket - you need a 3D printer filament you can rely on, something that won’t ruin your prints half way through with blockages or jams. Something that produces the finished article in excellent detail, with no stringing or blobbing.’s ASA printer filament does exactly that.

We’ll even swap or refund it up to 60 days after purchase if you have problems, or simply find it’s just not for you – who else does that?

Free from contaminants and hidden foreign objects; our resins are extremely smooth and predictable to print with. Layer adhesion is unmatched, meaning your ASA prints will be strong and long lasting, every time.

Often overlooked by others, we’re extremely strict on our dimension tolerances. If you’re getting fluctuations in diameter, even by small margins, your prints will have varying thickness areas, which could turn into fault and high stress points. That’s why we pride ourselves on an industry leading 0.03mm+/- either side of the 1.75mm we promise on all filaments (except flexi filaments). Say goodbye to extruder jams, and hello to smooth, strong prints.

Save time and wasted resources with a 3D printer filament you can rely on. 

Like the colours you see in the photos? That’s the colour you’ll receive, and the colour your prints will finish like. Often some filaments have poor pigments, that look washed out or even loose saturation during the heated printing process – leaving washed out colours. Our natural ASA comes in a slightly off-white colour, but won’t yellow over time, even in sunlight.

So, why wait? Our ASA 3D printer filament is an excellent addition to your 3D printing library. Order a 1kg reel or 10m sample today. 

We also have ASA testing packs available - Click here to take a look.

Just a side note, as with all ASA filaments, please turn your printer’s cooling fan low and ensure it’s not printing in a draughty environment. ASA needs to cool slowly, (like ABS) to prevent warping.

Nozzle temperature needs to be around 230C, with a heated bed of 90-110C, lowering a few degrees after the first couple of layers.

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.

Rigid ink ABS 1 Kg 1.75mm Silver

I'am very pleased with this roll of filament. It prints really well and produces a great surface finish with little contraction and warping even on large prints. After vapour smoothing the surface quality is FANTASTIC. I'm so pleased I've used it all up and have just ordered another 1Kg. Best prints for me come out at a temperature of 245 C, with a bed temp of 95 C, 0.4mm nozzle and I'm using a Willson 2 ( reprap ) printer of my own manufacture. I've yet to try the reel of ASA I also brought, so I will write a review of that when I get to it.

Using this for commercial products

I've switched to Rigid Inks ASA to manufacture products I sell commercially for use outdoors. It's the first time I've printed with ASA and it was pretty successfully nfrom the start...mostly because of the tips provided on the box and via email. I'm printing directly on a PEI bed without hairspray and finding that seems to work best with very few prints warping. The end result is a very strong finished product, so I'm really pleased with the filament. It would be great to see a grey introduced in future as I have some demand for that colour.

ASA 3mm filament. Perfect prints every time

My favourite filament to date. Really good prints in a material that can be used for working parts. Admittedly, I do have an enclosure to protect the print from sudden temperature changes. The only downside is that there are only two colours available in 3mm filament.

Hi John,

Thanks for leaving us a review.

It's great to hear that our ASA has made you some good working parts.

Thanks also for letting us know that you'd like to see more colours.

I've made a note of this.

Let us know if you have any more comments or queries.

Best of luck with your printing!

All the best,
Rigid Ink ASA is, so far, the best filament I have used!

I believe I am using my 3rd roll of this filament, right now. I use it to print parts for a client, that are used in some kind of machinery to hold sensors. I appreciate the easyness and constancy of the results I get.

That 3rd roll is not going to be the last!

Smoother finish compared to cheaper ASA

Rapid ink ASA has a better consistency and finish compared to cheaper ASA. Easy to use with a heated bed. Not tried large pieces but very happy with quality of smaller pieces. Using ASA to build MK2 of our 3d printer.
