PA 640-GSL Carbon & Glass-Filled SLS Printing
PA 640-GSL Nylon 12
Our SLS Carbon & Glass-Filled Material
When your SLS 3D printed parts need serious structural muscle without acting like an anchor, lightweight PA 640-GSL Nylon 12 delivers the ultimate win-win. By combining high-modulus carbon fibers with weight-slashing hollow glass spheres inside a rugged polyamide 12 powder matrix, this composite yields a phenomenal stiffness-to-weight ratio that practically laughs in the face of gravity. You get the exceptional structural rigidity, low warp, and dimensional stability demanded by high-performance aerospace, drone, and motorsport components, all while shedding critical grams. Ditch the false choice between heavy-duty strength and nimble agility when you can effortlessly print both in a single run.
PA 640-GSL Features
- Dark Gray — High-Detail Surface
- Carbon fiber increases the dimensional stability
- Hollow glass beads add increased durability
- Good Strength-to-Weight Ration Properties
- PA 640-GSL (0.82 g/cm³) is about 12–18% lighter than standard PA 12 (0.93–1.00 g/cm³)
- ~10% Reduction of Material-Per-Build Compared to Similar Nylon 12s
- Developed for the UAV industry

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.
