Bambu Lab PAHT-CF Carbon Fibre Nylon

 

Bambu PAHT-CF is a unique composite material that combines PA12 (Nylon 12) and carbon fiber. This composite inherits the low water absorption property of PA12 and the exceptional performance of carbon fiber, resulting in a filament with outstanding mechanical and thermal properties. Even when exposed to moisture, Bambu PAHT-CF maintains its high performance levels.

With higher Z adhesion layers and enhanced flexibility, Bambu PAHT-CF is an excellent choice for creating engineering parts, including functional prototypes, machining fixtures, injection molds, jigs, and low-volume production parts. Its superior properties make it ideal for applications where strength, durability, and resistance to moisture are essential. Whether you are in the field of engineering, manufacturing, or product development, Bambu PAHT-CF offers the reliability and performance needed for demanding projects.

 

Low Water Absorption

Bambu PAHT-CF stands out with its exceptional water resistance, boasting a water absorption rate that is 50% lower than regular PA-CF (Nylon-Carbon Fiber) materials. This lower water absorption rate is a key advantage, as it enables Bambu PAHT-CF to maintain excellent mechanical properties and dimensional stability, even when subjected to high humidity or moisture-rich environments.

The reduced water absorption of Bambu PAHT-CF helps prevent the material from absorbing excessive moisture, which can lead to dimensional changes, warping, and degradation in other materials. By retaining its mechanical properties and dimensional stability, Bambu PAHT-CF ensures reliable and consistent performance throughout its lifespan, even in challenging conditions.

Incredible Z-Bonding

Bambu PAHT-CF exhibits superior adhesion in Z layers compared to regular PA-CF (Nylon-Carbon Fiber) materials. This enhanced adhesion contributes to its exceptional ability to withstand high levels of impact or stress without breaking or deforming.

The improved Z layer adhesion of Bambu PAHT-CF ensures strong interlayer bonding, resulting in a more robust and durable printed part. This means that the material can effectively distribute and absorb impact forces, making it highly resistant to fractures or deformations even under demanding conditions.

Smart Printing with RFID

With Bambu PAHT-CF, all the essential printing parameters are conveniently embedded in an RFID chip. This RFID chip can be read by our AMS (Automatic Material System), eliminating the need for manual configuration and tedious setup steps.

Simply load the filament onto the printer, and the AMS will automatically detect the material and retrieve the corresponding printing parameters from the RFID chip. This streamlined process saves you time and effort, allowing you to start printing right away without the hassle of adjusting settings.

Say goodbye to manual parameter input and enjoy a more seamless and efficient printing experience with Bambu PAHT-CF and our integrated AMS technology.
