PA12 S (Arkema)
Reference material for industrial 3D printing with MJF technology
PA12 S (Arkema) is a technical polyamide for MJF 3D printing that stands out for its high mechanical resistance, dimensional stability and durability. At Additium3D, we use it to manufacture functional prototypes and final parts for industrial production.
Maximum resistance, stability and repeatability for industrial production
What is PA12?
The Polyamide 12, also known as Nylon PA12 or Polyamide 12, it is a highly versatile technical thermoplastic widely used in industrial manufacturing for its excellent mechanical properties and its high stability against wear, moisture, and temperature changes.
When combined with technology Multi Jet Fusion (MJF), PA12 allows for the manufacture of complex parts with great precision, without the need for moulds, and with practically isotropic properties.
Therefore, it is one of the reference materials for industrial additive manufacturing.
LET'S TALK
Principales propiedades de la Poliamida PA12La poliamida PA12 es un termoplástico de alto rendimiento conocido por su excelente equilibrio de propiedades. Sus características más destacadas incluyen:* **Baja absorción de humedad:** A diferencia de otras poliamidas, la PA12 exhibe una absorción de agua significativamente menor, lo que se traduce en una mayor estabilidad dimensional y propiedades mecánicas más constantes en entornos húmedos. * **Excelente resistencia química:** Es resistente a una amplia gama de productos químicos, incluyendo aceites, grasas, disolventes, combustibles y fluidos hidráulicos, lo que la hace ideal para aplicaciones en automoción e
High mechanical strength
It is capable of withstanding continuous loads and mechanical stresses without deforming easily, making it ideal for functional components.
Excellent dimensional stability
The parts maintain their dimensions even after long periods of use or under moderate temperature changes.
High wear resistance
Its behaviour in the face of abrasion and continued use makes it a perfect material for parts subjected to friction.
Good chemical resistance
It offers high resistance to oils, greases, fuels and numerous chemicals used in industrial environments.
Uniform finish
Thanks to technology MJF PA12, The parts present a homogeneous surface and an excellent finish, reducing post-processing needs.
Sustainable material
The Arkema PA12 S It offers a recyclability rate of over 90 %, allowing a large proportion of the unsintered powder to be reused during manufacture.
