Prusament PETG Jet Black 1kg Refill - Made in USA

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.

Prusament PETG is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.02mm precision and highly-consistent colors. You can inspect parameters of every spool we made at prusament.com. Check the sample spool!

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 and highly-consistent colors in our filaments.
