About this item

• Manufactured in-house by Prusa Polymers - We were not satisfied with the quality of filaments on the market. So we decided to make our own. As a part of Prusa Research companies group, we are 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.
• High Quality you can check yourself - We are the only manufacturer that 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.
• 0. 02 mm Manufacturing Precision - We believe the industry standard of 0. 05 mm isn’t sufficient for perfect 3D printing. Instead, we 0. 02mm precision and highly-consistent colors in our filaments.
• Prusa Galaxy Black is inspired by the frame of our Original Prusa i3 printers.

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 MATERIALS AND THOROUGH TESTING

The whole manufacturing process is closely monitored – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.

± 0.02 MM PRECISION OF FILAMENT

We believe the industry standard of 0.05 mm isn’t sufficient. We are manufacturing our filament with ±0.02mm precision for the vast majority of materials. We're also focusing on highly-consistent colors.

QUALITY YOU CAN CHECK YOURSELF

We are the only manufacturer that 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.

PLA is the most commonly used filament. It’s a very strong, easy to print and biodegradable material. The perfect choice for printing large objects thanks to its low thermal expansion (with little to no warping) and for printing tiny parts because of its low melting temperature.

Tips for printing

To achieve the best adhesion of the print surface, it is important to keep it clean. Cleaning the surface is simple: the best option is Isopropyl alcohol (available in drugstores) which works best not just for PLA, but other materials as well.

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 make it hard to keep sanding.

Feel free to cool PLA during printing as much as possible. With good enough cooling you can print extreme overhangs and bridge between far away surfaces.

Characteristics

Application

Action figures

Action figures often include tons of small features. Printing them with PLA is easy at almost any scale

Jewelry

PLA is perfect for printing small and detailed objects, such as jewelry. Whether it’s a necklace or an earring, you can expect clean edges and no stringing, especially if coupled with a smaller nozzle.

Large prints

Thanks to its minimal thermal expansion, PLA is a great choice for large prints. No warping, no layer separation. Use your build volume to its maximum potential!
