Welcome back, 3D printing enthusiasts! Today, we’re diving into the world of carbon fiber nylon, specifically polyamide-based filament infused with chopped carbon fibers. We’ve received a bunch of questions on this topic, and it’s time to provide you with the answers you’ve been looking for.
Engineering-Grade Awesomeness
Before we delve into your questions, let’s clarify what we’re talking about. Carbon fiber nylon, in this context, doesn’t involve the fancy anisoprint or Markforged-style carbon fiber tows woven into parts. Instead, we’re discussing polyamide polymers with chopped carbon fibers mixed in. These carbon additives significantly boost rigidity, stiffness, thermal deflection temperature, and dimensional accuracy. This makes it ideal for a wide range of applications, from automotive parts to jigs, fixtures, welding fixtures, and more.
Can Your 3D Printer Handle It?
One common question is whether your 3D printer can handle carbon fiber nylon. For many consumer 3D printers like the Ender 3, the challenge lies in reaching the required temperatures. The Ender 3, for instance, typically maxes out at around 260°C due to the PTFE lining in the hot end. This lining breaks down at temperatures around 240-250°C, which is not suitable for printing carbon fiber nylon. However, there’s a solution. Upgrading to an all-metal hot end, such as the Mosquito or Micro Swiss, opens up the world of carbon fiber nylon printing. These hot ends can handle the higher temperatures needed for this filament.
Keep in mind that larger prints can be challenging on open-air printers due to cooling and warping. Enclosed chamber printers, especially those with actively heated chambers, are better suited for large nylon prints.
Heated Chamber vs. Non-Heated Chamber
A great suggestion from one of our viewers is to compare the results of printing carbon fiber nylon with and without a heated chamber on the same printer and part. This can provide valuable insights into the impact of chamber temperature on the print quality and performance of this filament. We’re considering this idea for a future video.

Endless Possibilities
Carbon fiber nylon isn’t limited to industrial applications. In fact, it’s so versatile that people are 3D printing entire drones out of nylon. Whether it’s the body of a drone, an antenna mount, or a GoPro mount, this material proves its worth in various scenarios. It’s durable and can handle demanding tasks.
Choosing the Right Carbon Fiber Nylon
With so many options on the market, it’s essential to select the right carbon fiber nylon for your specific needs. Various brands offer different blends of carbon fiber nylons, such as CFPA6, CFPA12, CF HTM, and more. The key is to understand what you require in terms of chemical resistance, heat resistance, and mechanical strength. Not all carbon fiber nylons are created equal, and it’s important to choose the one that best suits your application.
What’s in the Blend?
It’s worth noting that many carbon fiber nylons are not pure nylon but are blends with other additives. These additives are used to improve printability, flow, temperature resistance, and other properties. So when you’re printing with carbon fiber nylon, you’re often working with a mix of materials tailored to deliver specific performance characteristics.
Material Considerations
One crucial aspect is the wear and tear on your 3D printer’s nozzle. Carbon fiber is incredibly abrasive, and after printing approximately 200 grams, a 0.4mm nozzle can degrade into a 0.8mm nozzle, resulting in poor print quality and accuracy. To combat this, it’s essential to use a hardened steel nozzle or a similar nozzle material that can withstand the abrasive nature of carbon fiber-filled filaments.
While cooling fans are sometimes necessary for small parts, they’re generally not recommended when printing nylon or other high-temperature polymers. Nylon can get too hot and transfer heat through the part, leading to issues like warping and oozing. Cooling fans can create more problems than they solve in these situations.
The Hygroscopic Nature of Nylon
One significant characteristic of nylon is its hygroscopic nature, meaning it absorbs moisture from the air. Before printing, it’s crucial to dry the filament to prevent the moisture from turning into steam and causing bubbles or defects in your 3D prints. Drying nylon is a crucial step in the process to ensure high-quality results. Dehydration usually occurs at temperatures between 80-90°C, and it can take anywhere from 48 to 72 hours or longer to complete the drying process effectively.
To make your drying process more efficient, consider using a vacuum chamber and our drying kit, which can significantly speed up the drying process. Additionally, using filament spools designed to allow even heat distribution, like the ones available at Vision Miner, can help maintain the quality of your nylon filament by ensuring it’s uniformly dried.
