New carbon fiber PETG Filament at Winkle

3D printing continues to evolve and we at Winkle are excited to introduce our new PETG Carbon Fiber filament, an advanced material that combines the best of carbon fiber’s mechanical strength with the versatility and ease of use of PETG.

This innovative filament is available in an elegant Carbon Black color, ideal for those looking for functionality and style in their 3D printing projects.

What is PETG Carbon Fiber?

PETG (Polyethylene Terephthalate Glycolized) is one of the most widely used materials in 3D printing due to its balance of ease of printing, durability and impact resistance. Now, when combined with carbon fiber, this material becomes an advanced option for projects that require superior mechanical properties and high dimensional stability.

Carbon fiber filament for 3D printers is basically PETG reinforced with carbon fiber particles. This reinforcement improves the mechanical properties of the material, making it more rigid, tensile resistant and with better thermal resistance. But what does this mean in terms of performance?

Carbon Fiber PETG Composition and Manufacturing Process

Carbon fiber filament is composed of a PETG base enriched with carbon fibers, which are evenly distributed during the filament extrusion process. These fibers act as reinforcement, providing the material with increased strength and stiffness without sacrificing printability.

The manufacturing process begins with the combination of the base polymer, in this case PETG, with the carbon fibers. This compound is extruded into uniform yarns that are then wound onto spools ready for use in 3D printers.
Precise control during extrusion ensures that the carbon fiber filament maintains consistent quality, resulting in more accurate and better finished prints.

Properties of PETG Carbon Fiber

Carbon fiber PETG is distinguished by a number of properties that make it ideal for industrial and functional applications. Below, we analyze the most outstanding characteristics:

1. High mechanical strength: the carbon fibers embedded in the filament provide a marked improvement in the tensile strength and stiffness of the material. This means that parts printed in carbon fiber 3D filament can withstand higher stresses without deforming or breaking.
2. Excellent dimensional stability: thanks to the carbon fiber reinforcement, the material is less prone to deformation during printing or under mechanical loading conditions, maintaining its shape and accuracy over time.
3. Printing temperature: for printing with carbon fiber PETG, an extrusion temperature of between 230°C and 245°C is recommended, depending on the 3D printer and the type of nozzle used.
4. Hot bed temperature: the hot bed should be maintained between 60°C and 80°C to ensure good adhesion of the first layer and avoid warping. Like standard PETG, carbon fiber reinforced PETG has good adhesion to the bed, but it is recommended to use specialized adhesives or foils to ensure a better result.
5. Thermal resistance: parts printed with carbon fiber filament also show higher resistance to elevated temperatures compared to standard PETG.
6. Satin surface finish: Winkle’s PETG carbon fiber filament offers a satin finish with a light reflectivity that softens light, while its subtle texture adds a modern industrial touch, ideal for functional parts with a robust, professional aesthetic.

Uses and applications of Carbon Fiber PETG

PETG with carbon fiber has a wide range of applications due to its advanced characteristics. Here are some of the most common uses:

1. Functional prototypes: for engineers and designers who require functional prototypes that can withstand mechanical testing, carbon fiber filament is the ideal choice. The material’s strength and stiffness make it possible to create parts that closely simulate the performance of final parts.
2. Industrial parts: Carbon fiber filament for 3D printers is highly valued in the industrial field, where durable, wear-resistant parts need to be manufactured. This material is used to produce parts such as brackets, connectors and structural components in sectors such as automotive, aeronautics and robotics.
3. Lightweight and strong components: thanks to the lightness of carbon fibers, this material is perfect for applications where a balance between weight and strength is needed. This includes everything from drones and vehicles to portable devices.
4. Custom and end-use parts: PETG carbon fiber’s surface finish and strength make it ideal for the production of end-use parts in small batches, especially in sectors where design and functionality are key, such as consumer electronics and custom devices.

Comparison between Carbon Fiber PETG, Standard PETG and Crystal PETG

It is important to understand how carbon fiber filament compares to other types of PETG in order to choose the right material for each project.

• Carbon Fiber PETG: offers higher mechanical strength and stiffness, ideal for functional and mechanical applications. Its industrial finish is visually appealing and it has better thermal resistance than standard PETG.
• Standard PETG: more flexible and easier to print, but lacks the strength and stability of carbon fiber PETG. Excellent choice for parts that are not subjected to high loads.
• Crystal PETG: has a translucent and shiny appearance, ideal for decorative parts or parts that require a certain level of transparency.

Is PETG carbon fiber better than PLA?

It will depend on the specific needs of your project. A comparison is provided below:

• Strength and stiffness – PETG carbon fiber is significantly stronger than PLA. If you need parts that will withstand mechanical stress or be durable, PETG with carbon fiber is a superior choice.
• Lightweight: the incorporation of carbon fibers reduces the weight of the material without compromising its strength.
• Thermal resistance: PETG with carbon fiber has better resistance to high temperatures compared to PLA, which tends to deform or soften at relatively low temperatures.
• Ease of printing: PLA is easier to print for beginners, with fewer temperature requirements and adjustments. Carbon fiber PETG requires a little more precision in printer setup, but the performance benefits outweigh that extra effort.

Winkle’s PETG carbon fiber filament is an innovative, high-quality option that combines the strength and durability of carbon fiber with the versatility of PETG.
