What can you expect?
Prusament Refill is an environment-friendly way to refill your empty Prusament spool. Once you run out of Prusament and the spool is empty, simply remove the spool's sides and attach them to Prusament Refill which comes wound on a spool core.
Every Prusament Refill we made is up to the high quality standards of our in-house made filaments and is well-secured for transport, so you don't have to worry about tangled spools.
How to fit Prusament Refill spool
The Prusament spool consists of black plastic sides and a cardboard centerpiece. The sides are pushed on the centerpiece and can be removed to reuse or recycle. Please note there are also gray Prusament spools used for high performance. Those are glued to the cardboard centerpiece as some filaments require drying up in high temperatures.
The trick to easily separate the center of the spool from the plastic sides is to rotate the spool. Pull the ends of the spool apart using a reasonable amount of force and gradually rotate the spool bit by bit. Thanks to this movement, it will be easier to separate the sides from the center of the spool.
More detailed instructions on how to fit the Prusament Refill spool can be found on the help.
Prusament PLA is Prusa Research's own in-house made filament. The whole manufacturing process is closely monitored and tested - they guarantee ±0.02mm precision and highly-consistent colors. You can inspect parameters of every spool made at prusament.com. Check the sample spool!

Manufactured In-House By Josef PrusaPrusa Research was not satisfied with the quality of filaments on the market. So they decided to make their own! Prusa Research is the only 3D printer manufacturer with its own filament production. |
Premium-Grade Materials And Thorough TestingThe 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 PrecisionPrusa Research believes the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, they guarantee ±0.02mm precision and highly-consistent colors in their filaments. |
High Quality You Can Check YourselfPrusa Research is 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 PLA
PLA melts at a relatively low temperature of about 175 degrees Celsius. Unlike so-called thermoset materials, PLA can be heated past its melting point multiple times with very little degradation. It’s a hard material, but that also means it’s somewhat brittle, and once it breaks, it likes to shatter. Only this material is proven for 50 microns layer height.
However, PLA is not a perfect material and, just like every other plastic, has some disadvantages. The low melting temperature also means low-temperature resistance. Parts start to lose mechanical strength at temperatures over 60 °C.
The combination of being low in UV and temperature resistance means that it’s not ideal for outdoor use. Also, PLA is only soluble in chemicals like chloroform or hot benzene. So when connecting multiple pieces, you’re better off using just glue.
Even though PLA is on its own food safe, Prusa Research does not recommend repeatedly drinking or eating from your 3D prints. Because of the small fractures on the print surface, bacteria can build up in there over time. You can prevent this by applying a food-safe coating. When post-processing PLA, it’s better to use wet sanding. Without water, you'll quickly start heating the plastic by friction, which will cause it to soften and make it hard to keep sanding.

United StatesGreat filament, great shipping
Filament is quality you’d expect from Prusa, so great. Shipping and experience with printed solid was excellent and fast
United StatesQuick and easy
It’s great having Printed Solid in the U.S. to deliver Prusament and other items more quickly and cheaper from overseas. Will be buying again.
United States United States United StatesGreat stuff!
Love this filament. Prints well and is extremely consistent. Super glad that I'm able to get it in the US quickly now!
