Prusament ASA Prusa Galaxy Black 850g

What can you expect?

Prusament ASA is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.03mm precision and highly-consistent colors. You can inspect the parameters of every spool we made at prusament.com. Check the sample spool!

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 Guaranteed 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

We are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool).

About ASA

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.

You can find more details about printing with ASA in our in-depth article.

I needed a strong filament for outdoors and higher temperature use and this fit the bill perfectly. I put my printer in an enclosure and then modified my Prusament PETG profile to set the hotend to 260C and the bed at 105C. With the enclosure at 45C this printed beautifully without any warping issues. In early testing if I let my enclosure get into the 30s I had some issue with thin sections lifting slightly from the bed. This was solved with a little more ambient temperature. I have been able to successfully print on both my textured PEI surface and the smooth side. Both laid down easier than PETG and once I allowed the bed to cool the parts popped off easily. The surface finish is more matte and not quite as dark as the PETG galaxy black, closer to a charcoal gray. This still looks great and very presentable. It bridges better than the PETG and the sides look smoother, hiding the layer lines better than the glossier PETG filaments. This allowed me to create strong handles for my daughter's school band podiums which will live in the sun every day. My only disappointments are I didn't order more, and I wish they could expand their ASA color offerings.

Printed like butter on my Prusa MINI. 0 warping in a home made enclosure. Quality is awesome. Too bad the color selection is so limited.

Experienced like no warping printing this (did not lift a single corner after using 2 spools). Small details like threads are printing nice. Adhesion to the smooth PEI sheet is perfect.(might even be a bit too good). (Printed in an enclosure with 32-39°C)
