PA2200 (PA12 white)
SLS 3D printed components made from PA2200 (PA12 white) feature balanced material properties, making them ideally suited for functional components of all kinds. The material Polyamide 12 is a multi-purpose material, characterized by its high strength and stiffness, good chemical resistance, and good post-processing capabilities. Thanks to its durability and wear resistance, PA12 is ideal for long-lasting applications under mechanical stress. SLS 3D printed components made of PA12, which have been chemically smoothed after the printing process, are 100% pressure-water tight and feature an injection molding-level surface. The material PA2200 is biocompatible according to EN ISO 10993-1 and USP/Level VI/121°C and certified for food contact according to EU Plastic Directive 2002/72/EC (with the exception of highly alcoholic beverages).
PA2200 also offers high process reliability and is cost-effective to manufacture. Thin-walled geometries and film hinges can also be reliably realized with PA2200. PA2200 is one of the most commonly used materials in selective laser sintering and complies with EU regulations RoHS and REACH.

Frequently Asked Questions - SLS Materials
The most commonly used material in SLS 3D printing is PA12 (polyamide 12). It is considered a versatile all-round material with balanced mechanical properties such as high strength, good rigidity, and excellent chemical resistance. This makes it suitable for a wide range of applications , for example, for housings, brackets, technical functional components, prototypes, or small-series components.
TPU (thermoplastic polyurethane) is particularly suitable for components that need to be flexible or provide a seal. This material possesses elastic properties and behaves similarly to rubber. This allows components to absorb movement, provide a seal, or compensate for slight deformations. We process the TPU1301 material from EOS.
For components with particularly high rigidity, PA3200GF is suitable, a glass-filled polyamide 12. The glass particles in the material result in significantly higher rigidity and dimensional stability. At the same time, the material remains highly wear-resistant and temperature-resistant, making it well-suited for mechanically stressed components.
PA11 is considered a more sustainable material option in SLS 3D printing. This polyamide is produced from vegetable oil and is therefore based on renewable raw materials rather than exclusively on fossil resources. At the same time, PA11 offers excellent mechanical properties and high toughness, making it suitable for functional components under mechanical stress.
Both materials are flame-retardant polyamides for applications with increased fire protection requirements. PA2210 FR contains a halogen-free flame retardant and is often used in areas where strict safety or electronic standards must be met. In contrast, PA2241 FR contains a halogenated flame retardant and is frequently used in aviation due to its properties. Both materials offer good mechanical properties and are suitable for technical components with increased safety requirements.
