Prusament PA11 Natural is made in-house by Prusa Research.

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.
