Prusament is a premium-grade material made by the same people who build the printers. Every spool is manufactured in-house with consistent color and ±0.02 mm precision. You can verify it yourself, down to the last meter.
Every Prusament color is formulated and locked to a documented spectroscopic recipe. We test every batch against the standard before it ships. The result: if you run out mid-project and order a second spool, the colors will match perfectly.
Some manufacturers claim similar numbers, but claims without proof are just marketing. We measure and record diameter and ovality continuously across the full length of every spool, and we publish the actual data.
Every Prusament spool comes with the actual measured data from manufacturing: diameter readings along the entire length, weight, and ovality. We're the only filament manufacturer in the world that does this.
Our PLA filament is wound under controlled tension on precision machines. Every spool goes through a final inspection before shipping. The result is a spool that feeds smoothly from start to finish. Also, it looks great every time.
Prusament is manufactured in our facilities in the Czech Republic (Europe) and Delaware (United States). That means faster shipping, lower import duties where applicable, and a supply chain under our full control.
There's no third-party manufacturer who can quietly change a raw material supplier. No surprise batch failures from a factory you've never visited.
PA11 is a type of polyamide used primarily in SLS technology and is very rare in the field of FFF 3D printing. Commonly used PA6 and PA12 polyamides have several disadvantages: PA6 is extremely hygroscopic, making it very difficult to print with it even 1 day after unpacking. PA12 isn’t as hygroscopic, but it warps extremely and has very poor adhesion to standard print sheets. PA11 is a good middle ground – it’s less hygroscopic, warps less, and offers better adhesion to various print surfaces.
Prusament PA11 offers low friction and good abrasion resistance. Combined with decent mechanical properties (impact and tensile strength), it's perfectly suitable for printing gears and other moving parts.
PA11 has good resistance to bases (e.g. NaOH), alcohols (Methanol, Ethanol), toluene, acetone, motor oil, petrol, diesel, etc. This makes it usable in laboratories and, again, in automotive and other demanding industry fields.
Prusament PA11’s tensile strength anisotropy coefficient reaches r=0.84 when printed with Prusa Core One+. This is the highest value of all Prusaments. This means the material is much harder to break and withstands stress in every direction, no matter the layers’ orientation. This vertically printed umbrella holder serves as a good example.

Starting October 2025, all Prusament filaments ship on a redesigned spool with a fully rewritable NFC tag powered by the OpenPrintTag standard.
The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app. It works entirely offline, it is free to extend, and open for anyone to build upon.
Before printing, learn about print surface preparation in our dedicated article and material table.
Prusament PA11 can easily peel and warp when printed on conventional sheets. Sure, smaller models with sparse infill can be printed on PEI sheets coated with stick glue, but for reliable printing of technical models, you need something better. Prusament PA11 in particular can easily peel and warp when printed on conventional sheets. That’s why we have developed a new surface layer of a special material that provides significantly better adhesion for polyamide printing materials.
