PA 850 Black SLS Printing
PA 850 Nylon 11
Our SLS Melt Mixed Black Material
Stronger parts start with smarter material. Engineered from renewable castor oil, Nylon 11 PA 850 Black combines extreme impact resistance with high ductility to ensure your components flex rather than fracture under pressure. This melt-mixed, dark-hued powder delivers deep, uniform color through a single laser scan, saving valuable production time while hiding surface scratches and wear over time. Designed to maintain its structural integrity in brutal sub-zero temperatures, it offers superior tensile strength, a smooth surface finish, and a low coefficient of friction for sliding mechanical assemblies. If you want high-performance additive manufacturing without the delicate touch, this resilient bio-polymer keeps your additive production moving forward.
PA 850 Black Features
- Black
- For applications that require slightly higher tensile strength at break, along with a higher elongation factor
- All-weather performance, it excels in extreme climates
- High-impact and high-pressure resistance at sub-zero temperatures
- Low coefficient of friction
- Not bio-compatible

Choosing Your 3D Printing Champion
Picking the right material shouldn't feel like a chemistry quiz, so let's break down the two heavyweights of SLS printing. If you need parts that bend but refuse to break, meet Nylon 11. Born from castor oil—yes, you get green bragging rights—this eco-friendly powerhouse offers incredible impact resistance, making it your go-to for living hinges and high-pressure environments. On the flip side, Nylon 12 is the reliable industry baseline synthesized from petrochemicals. It trades flexibility for rigidity, delivering rock-solid dimensional stability that makes it perfect for complex housings, rugged enclosures, and economical production runs.
