Material Overview

KSPA12BK is a black nylon powder with a particle size D50 of about 50 microns and a narrow and uniform distribution. It can be sintered using fiber laser or carbon dioxide laser, and the powder has high sphericity and extremely high fluidity. The powder reusability rate can be close to 100%, and the 3D printed parts can maintain excellent mechanical properties and excellent surface finish.

key properties
1. Sphericity and Fluidity:
The powder exhibits superior sphericity, which enhances flowability during processing. This characteristic is crucial for ensuring uniform layer deposition in 3D printing and consistent mixing in powder coatings.

2. Particle Size Distribution:
KSPA12BK has a narrow particle size distribution with a D50 of approximately 50 microns. This uniformity contributes to better packing density and improved performance in additive manufacturing processes.

3. Mechanical Strength:
Parts produced using KSPA12BK demonstrate excellent tensile strength, impact resistance, and durability. This makes it suitable for functional prototypes and end-use parts that require robustness.

4. Thermal Properties:
The material has a high melting point and good thermal stability, allowing it to withstand elevated temperatures during processing and in end-use applications.

5. Chemical Resistance:
KSPA12BK exhibits resistance to a variety of chemicals, oils, and solvents, making it ideal for applications in automotive, aerospace, and industrial sectors where exposure to harsh environments is common.

100% compatible with any SLS System

FAQs

Application cases of nylon materials on EOS machines — are all EOS models compatible?


Our PA12 and PA12GF can be used on EOS models such as P760, P110, and P396.

Yes, parameter adjustments are needed, mainly including melting temperature and heat deflection temperature.

In terms of stiffness, heat resistance, toughness, and elongation, our materials are lower than EOS. The main advantage lies in the price, as well as the mixing ratio of new and used powder, which helps reduce costs.

Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
