Large-Format Continuous Carbon Printing on FX20

Manufacturers currently encounter the challenge of producing stronger components at an accelerated pace and in greater quantities, while simultaneously adhering to stringent deadlines. The Markforged FX20 addresses this challenge as a next-generation 3D printer that facilitates the integration of Continuous Fiber Reinforcement (CFR) technology for high-volume production. This blog will examine how the FX20 enhances the capabilities of 3D printing within sectors that require aerospace-grade performance, coupled with 

unparalleled flexibility.

What Is the FX20?

The FX20 is Markforged’s most powerful and largest 3D printer to date. It is specifically designed for creating parts reinforced with carbon fiber, and it operates at a larger scale than ever before. Built for high throughput and demanding industrial environments, the FX20 features in-layer fiber placement technology that delivers unmatched strength-to-weight ratios for parts that are comparable to machined aluminum.

Key Features of the FX20

• Large Build Size: The FX20 has dimensions of 525 x 400 x 400 mm, allowing it to create large parts in a single print, which eliminates the need for part segmentation or post-assembly.
• High-Temperature Specific Uses: The FX20 is specifically designed for high-performance polymers, such as Onyx™ FR-A and Vega™ PEKK, both of which are flame-retardant and aerospace-grade. 
• Precision at Scale: Despite its large size, the FX20 features industrial-grade motion control with closed-loop feedback, ensuring a high level of dimensional accuracy and consistent layer quality.
• Faster Lead Time: By utilizing two nozzles and other heated components, the FX20 reduces cycle time, enabling the production of large, strong parts without the need for molds or machining.

Why Scale Matters in CFR Printing

The introduction of large-scale CFR printing creates new opportunities in industries with typically limited manufacturing capabilities.

• Aerospace & Defense: Ducting components, brackets, and housings that need to be strong and flame-resistant.
• Automotive & Motorsports: Mounting jigs, aerodynamic components, and structural housing for load-bearing applications.
• Industrial Tooling: Tools, fixtures, end-of-arm tooling, and custom production aids.

In the past, producing these parts required extensive machining or composite lay-up. Now, they can be 3D printed efficiently in a single piece, effectively managing weight, cost, and lead time.

The FX20’s Role in Digital Transformation

The FX20 seamlessly integrates with Markforged’s cloud-based Eiger software, which allows users to monitor printers remotely, assign fiber paths, and oversee production parts. This integration significantly enhances the scalability of part size and facilitates enterprise-level deployment.
