DATA - Rilsan® PA11
Advanced Bio-Circular (ABC) Materials
Arkema is a pioneer in amino 11 chemistry. Our flagship Rilsan® PA11 elastomers have a proven legacy in meeting some of the world’s most demanding material challenges. This chemistry is derived from the castor bean, a sustainable, renewable crop that does not compete with food and does not cause deforestation. These are not "just" bio-based materials, however. They are truly advanced polymers that ultimately help the world reduce its carbon footprint... a carbon footprint that is further reduced when these ABC polymers are recycled & reused.
Don't let the common misconception about bio-based materials fool you when it comes to 3D printing! That's right, the backbone of Rilsan® PA11 is 100% based on a feedstock of castor oil AND there is no compromise in performance when compared to its closest relative, non-bio-based PA12.

3D printed Rilsan® PA11 parts can pass the interior part crash test for automotive applications, an extreme situation that most other 3D printed materials fail. Due to this incredible impact resistance PA11 also passes the safety standards for bicycle helmets, and is being embraced by the cycling community, as seen in the HEXR example above.
The improved ductility of PA11 compared to PA12 allows designer to design thinner and lighter parts while using less material. The flexibility and durability of the material helps improve the lifetime of the part, yet if a failure does occur, the ductile breaking mechanism creates a safer environment compared to a brittle fracture seen in PA12 that could send dangerous shards into the air.
The graph below illustrates how a PA11 printed part under static load will maintain its mechanical strength over time compared to PA12 where we have observed up to 60% lower performance compared to PA11. This fatigue resistance is great for applications like the Bowman Rollertrain™ bearing cage shown above.
Kepstan® PEKK for powder bed fusion
Kepstan® PEKK (PolyEtherKetoneKetone) is the latest addition to the PAEK (Poly-Aryl-Ether-Ketone) family, and is ideally suited for metal replacement thanks to its very high service temperature, chemical resistance, and excellent fire retardancy.
The material of choice for metal replacement
Bringing cost saving solutions compared to subtractive technologies
Commercially available solutions for both amorphous or semi-crystalline parts
Easier to print than PEEK - Minimal part warping in FFF, higher recycle ability in SLS
High modulus and strength
Outstanding high temperature performance
Inherent flame resistance, low smoke generation, and toxicity
Excellent chemical resistance (oils, fuels, Skydrol, and hydraulic fluids)
Outstanding mechanical properties; wear, compression and impact
High dielectric strength and good insulating properties

Orgasol® Invent PA12 (Nylon 12) for powder bed fusion
Orgasol® Invent PA12 powders are ideally suited for powder bed fusion technologies. Parts made with Orgasol® Invent PA12 offer a great look & feel finish with great color durability. The very low refresh rate is also a key benefit to lower printing costs thanks to the high powder recyclability.
The material of choice for rapid prototyping
Reduce cost thanks to high recyclability
Excellent part detailing reminding injection molded parts
Among the lowest refresh rate in the market
Minimize post-treatment operation
Excellent color durability
Very low refresh rate
The recyclability of SLS powders is highly dictated by the evolution of the powder viscosity. Orgasol® Invent Smooth PA12 powders do not evolve under the SLS process temperature, indicating very high reusability of the powder after a production run.
Parts printed with Orgasol® Invent Smooth result in a very smooth finish compared to other PA12 powders on the market.
