Prusament PA11 Carbon Fiber Black is a Polyamide 11 filled with (recycled) carbon fibers<\/strong> to improve its strength and minimize warping. This material also has a great temperature resistance (up to 190 \u00b0C)<\/strong> and its mechanical properties are similar to our Prusament PC Blend Carbon Fiber – due to the impact strength and tensile characteristics, this material is especially suitable for the production of mechanical parts<\/strong>, such as gears and other models where durability is key.

Advanced materials such as the Prusament PC Blend Carbon Fiber greatly expand the possibilities of 3D printing and this is why we\u2019re bringing another new material to the market: Prusament PA11 Carbon Fiber Black<\/strong><\/a>, a material perfectly suited for use in the automotive industry<\/strong>, but also great for printing durable mechanical parts at home \u2013 components for drones and other RC models, gears and other technical parts.<\/p>\n\n\n\n

What is PA11?<\/h2>\n\n\n\n

Polyamides are a group of polymeric materials produced since the 1930s when DuPont developed polyamide 6.6 known by its trade name Nylon. This name has since become widespread and is often incorrectly applied to other types of polyamides. They are referred to by numbers that represent the number of carbon atoms of the parent compounds \u2013 e.g. PA6, PA6.10, PA12, etc.<\/strong><\/p>\n\n\n\n

The PA11 we use is a type of polyamide used primarily for SLS technology<\/a>. This is a rather unexplored area in the field of FFF 3D printing. We have experimented quite a lot in this field and finally achieved more than a good result. Why did we choose PA11? Commonly used PA6 and PA12 polyamides have a number of disadvantages: PA6 is extremely hygroscopic, making it extremely difficult to print with it even 1 day after unpacking. In some cases, PA6 can get absorb too much moisture even during long printing runs. PA12 isn\u2019t as hygroscopic, but it warps extremely and has very poor adhesion to a standard PEI print sheet. PA11 is a good middle ground \u2013 it\u2019s less hygroscopic<\/strong> and offers better adhesion<\/strong> to the PEI print sheet (for small and medium-sized models).<\/p>\n\n\n\n

Thanks to added carbon fiber<\/strong>, Prusament PA11 Carbon Fiber<\/a> is virtually non-warping.<\/strong> Compared to pure polyamide, it has slightly weaker interlayer adhesion, roughly comparable to our Prusament PC Blend Carbon Fiber<\/a> \u2013 still a very good result.<\/p>\n\n\n\n

Basic Mechanical and Chemical Properties<\/h2>\n\n\n\n

Polyamide PA11 is a material made from castor oil,<\/strong> the carbon fibers added to this filament are recycled,<\/strong> as with Prusament PC Blend Carbon Fiber.<\/a> Probably the biggest advantage of this material is its high-temperature resistance, up to 190 \u00b0C<\/strong> depending on the load. This makes it perfectly suitable for printing special parts, such as parts of machines that emit heat (motors, etc.). <\/p>\n\n\n\n

The second major advantage of PA11 (and polyamides in general) is its excellent chemical resistance to a range of solvents.<\/strong> PA11 has good resistance to bases (e.g. NaOH), alcohols (Methanol, Ethanol), toluene, acetone, motor oil, petrol, diesel, etc.<\/p>\n\n\n\n

Prusament PA11 Carbon Fiber<\/a> has good friction and abrasion resistance.<\/strong> This makes it suitable for printing gears and other moving parts. As for other mechanical properties (impact strength, tensile characteristics), these are similar to those of Prusament PC Blend Carbon Fiber<\/a>. For a better idea, we recommend looking at our material table<\/a>.<\/strong><\/p>\n\n\n\n
