About Prusament ASA

ASA is a technical material with properties similar to ABS but better in several ways. Compared to ABS, it’s UV stable, it doesn’t suffer from shrinking so badly and the fumes produced are much less noticeable. ASA 3D prints are durable, tough and suitable for a wide range of applications. ASA comes with much better high-temperature resistance than other common materials, such as PLA or PETG. It shows no signs of deformation up to temperatures near 93 °C. Thanks to all these properties, ASA is especially suitable for printing objects meant for long-time outside use.

Printing Setup

• Nozzle - 260±5 °C
• Heatbed - 110±5 °C
• Recommended Steel Sheet - Satin

Check Prusa's material table and print-surface preparation instructions before starting.

Basic Attributes

• Great for outside use – UV stable - Large models have a tendency to warp
• Good high-temperature resistance - Produces a slight odor of burned plastic during printing (less than ABS)
• Detailed prints without a stringing effect - Requires enclosure
• Can be smoothed with acetone vapors - Contains styrene (potentially harmful fumes)
• Can be easily sanded / post-processed - Slightly hygroscopic (absorbs moisture)
• Good mechanical resistance

New spools equipped with OpenPrintTag

Prusament filaments are wound on a redesigned spool that introduces several improvements for an even better printing experience, starting in October 2025. The new spool features a simple locking mechanism that makes disassembly quick and easy, allowing effortless refills. It also stays secure during filament drying, even at higher temperatures. And with its slimmer dimensions, the spool ensures compatibility with a wide range of multi-color and multi-material printing systems.

Every new Prusament spool now comes with a fully rewritable NFC tag powered by the OpenPrintTag standard. It’s designed to work across brands and ecosystems. It is free to use, free to extend, and open for anyone to build upon. Most importantly, it works entirely offline. All essential data is stored directly on the tag. Your printer can recognize the spool instantly, with no dependence on cloud services or vendor lock-ins. The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app.

What can you expect?

Prusament ASA is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.04mm precision and highly-consistent colors. You can inspect the parameters of every spool we made at prusament.com.

Prusament is produced by Prusa Polymers, with manufacturing checks throughout production.

Premium-Grade Materials And Thorough Testing The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.

Prusa specifies a filament diameter tolerance of ±0.04 mm. Check the product notes for blend-specific tolerances.

The spool's QR code gives access to its recorded production parameters.

Beginners tips & tricks

You may encounter some issues related to shrinking (warping) of the material – especially when printing larger models. This effect is much less severe compared to ABS but still, even with the heatbed set to 110°C, the prints can shrink and warp, causing them to detach from the print bed. This issue can be eliminated by printing inside an enclosure (for example our Prusa Enclosure) or by adding a draft shield around the object. It’s important to run the prints in a well-ventilated room because the material releases fumes and substances that could pose a potential health risk. When ventilating the room, do not create a draft around the print – this will negatively impact the result. You can find more details about printing with ASA in our in-depth article.

Notes This ASA is made in-house by Prusa Research. Starting from May 2024, all Prusament ASA spools have a tolerance of +- 0.04 mm instead of 0.03 due to changes to the manufacturing process. Before printing, make sure the surface of heatbed is clean as described in 3D Printing Handbook. To dry the filament, please follow the instructions in our article.
