Description

Bambu Lab PAHT-CF: High-performance

Advanced filament with carbon fiber reinforcement

Bambu Lab PAHT-CF is an advanced 3D printing filament made from high-performance polyamide (PA) blended with carbon fiber, providing exceptional strength and durability. This composite material is highly resistant to heat, making it ideal for applications that require high thermal stability and mechanical performance. The addition of carbon fiber enhances the filament’s rigidity, reducing warping and improving the structural integrity of printed parts.
