Small Batch Production KSPA12BK is the black variant of the proven KSPA12 nylon powder for selective laser sintering (SLS). It offers the same excellent mechanical properties as the standard material—high impact resistance, strong tensile strength, and outstanding flexibility—combined with the added benefit of a deep, uniform black color. This eliminates the need for post-dyeing, saving both time and post-processing costs.
With an elongation at break of 20%, the material is ideal for functional prototypes, flexible components, and snap-fit connections. Visually, KSPA12BK impresses with its consistent matte finish, making it particularly suitable for visible components and end-use parts.
Thanks to its optimal balance of performance and aesthetics, KSPA12BK is especially well-suited for applications in consumer goods, mechanical engineering, or serial production where both functionality and appearance matter.
