Prusament PLA Blend Royal Blue 970g

What can you expect?


Prusament PLA is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.02mm precision (± 0,03 for blends) and highly-consistent colors. You can inspect parameters of every spool we made at 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.

± 0.02 mm Manufacturing Guaranteed Precision

We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.02mm precision (± 0,03 for blends) and highly-consistent colors in our filaments.

About PLA

PLA is the easiest material to print. It is inexpensive and suitable for beginners and advanced users alike. It is capable of printing detailed models, figures, and quick prototypes that don’t require increased mechanical, chemical, or temperature resistance.

PLA is the most widely used filament, known for its great looks and ease of printing. It is an excellent choice for large objects because of its low thermal expansion, which results in minimal warping. At the same time, its low melting temperature makes it suitable for small parts as well.

While PLA may not be as tough or durable as some advanced materials, its versatility makes it ideal for a range of applications, including large objects, miniatures, concept models, and prototypes that don’t need to be extremely durable.

Beginners tips & tricks

Popular among both beginners and advanced users

PLA is the easiest-to-print filament we make. It’s reliable and it doesn’t require any print preparations or difficult post-processing methods. If you’re new to 3D printing, it’s best to start with PLA before using other materials.


When post-processing PLA, it’s better to use wet sanding. Without water you’ll quickly start heating the plastic by friction, it will melt locally and deform. Also, without water, the sanding material would clog easily.


PLA can be glued with many types of glue. We recommend using superglue for most of the parts. Certain PLA filaments may be also glued using acetone, however, it strongly depends on the various additives and colors used.


This PLA is made in-house by Prusa Research.

1.75 mm filament is manufactured with precision of ± 0.02 mm (±0.03 for blends)

Before printing, make sure the surface of the heatbed is clean as described in the 3D Printing Handbook.

If you choose a 2 kg spool, please download and print the 2kg spool holder as it will not fit the standard spool holder.

To dry the filament, please follow the instructions in our article.
