Prusament ASA is Prusa's own in-house made filament. The whole manufacturing process is closely monitored and tested - they guarantee ±0.03mm precision and highly-consistent colors. You can inspect parameters of every spool made at prusament.com
WHAT CAN YOU EXPECT?
MANUFACTURED IN-HOUSE BY JOSEF PRUSA
We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament 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.
± 0.03 MM MANUFACTURING PRECISION
We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.03mm precision and highly-consistent colors in our filaments.
HIGH QUALITY YOU CAN CHECK YOURSELF
Prusament gives customers the option to fully inspect parameters of every filament spool. Just scan a QR code on the spool to see all details online.
ASA can be considered a true successor to ABS. 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. The solidification temperature is also higher compared to PLA and PETG, which gives objects printed from ASA an excellent temperature resistance – there are no signs of deformation up to temperatures near 93 °C. Thanks to all these properties, ASA is especially suitable to print objects meant for long-time outside use.
However, you can still encounter some issues related to shrinking (warping) of the material – especially when printing larger models. Even with the heatbed set to 110°C, the prints can shrink and warp, causing them to detach from the print bed. However, the effects are much less severe compared to ABS. This issue can be eliminated by printing inside an enclosure or by adding a tall skirt around the object.
ASA printing requires specific conditions for successful results. 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. However, when ventilating the room, do not create a draft around the print – this will negatively impact the result.
Print sheet preparation
For ASA printing, we recommend using the smooth PEI spring steel sheet. With the powder-coated sheet, the adhesion of the material can be too strong, which could potentially result in damage to the surface of the sheet. The smooth sheet preparation is easy: simply clean the surface with isopropyl alcohol. To remove the print, wait until it cools down – it will then pop off easily.
Great for outside use – UV stable
High temperature resistance
Detailed prints without a stringing effect
Can be smoothed with acetone vapors
Can be easily sanded / post-processed
High impact and wear resistance
Large models have a tendency to warp
Produces odors during printing (less than ABS)
Not recommended to print on the Textured powder-coated steel sheet - very strong adhesion may cause damage to the steel sheet surface
This ASA is made in-house by Prusa Research.
1.75 mm filament is manufactured with precision of +- 0.03 mm
