CARBONara Carbon Fiber X Beam

**Don’t forget to grab a CARBONara install kit as well! Can be found here**

Transform your 3D Printer with ultimate performance by upgrading your Voron or Monolith 3D printer’s motion system with the revolutionary CARBONara Carbon Fiber X Beam. This precision-engineered replacement for your stock aluminum 2020 extrusion delivers unmatched performance, combining exceptional strength with dramatic weight reduction for faster, more accurate prints.

Key Features & Benefits

Ultra-Lightweight Construction Experience up to 58.8% weight reduction compared to standard aluminum 2020 extrusions. This dramatic mass reduction enables higher acceleration rates and printing speeds without compromising stability or introducing unwanted vibrations.

High-Temperature Durability Constructed with premium high-temperature resin rated for 110°C short-term temperature resistance, making it perfect for heated chamber printing up to 90°C. The advanced resin system ensures dimensional stability even under extreme thermal cycling conditions.

Exceptional Rigidity Multiple layers of precision-woven 3K carbon fiber strands provide superior torsional resistance compared to aluminum extrusions. The thoughtfully engineered design features rounded corners for enhanced structural integrity and improved stress distribution.

Battle-Tested Reliability Rigorously tested for over 800 hours at extreme speeds (500-1300mm/s) and accelerations (50,000-100,000mm/s²) in 80°C chamber conditions. This extensive validation ensures consistent performance under the most demanding printing scenarios.

Technical Specifications

Available Sizes and weight savings:

• 250mm build: 20x20x330mm tube (64.7g vs 157.1g aluminum – 58.8% Weight Reduction)
• 300mm build: 20x20x380mm tube (74.5g vs 181.0g aluminum – 58.8% Weight Reduction)
• 350mm build: 20x20x430mm tube (84.3g vs 204.8g aluminum – 58.8% Weight Reduction)

Installation Requirements

Critical Components: Printed inserts are a MUST during installation to ensure maximum performance. Ensure they are all facing the same direction during installation. Hollow spacers are not mandatory but are included as well to help facilitate with the installation. Both printed inserts and hollow spacers should fit snug and not loose.

The recommended filament to print inserts and hollow tubes should be printed in CF/GF filament with HDT ≥ 110°C, such as, PET-CF, PCPBTGF.

Compatibility

Designed specifically for Voron and Monolith gantry-style 3D printers using stock build volumes of 250, 300, and 350mm. For Voron installations, new XY-joints without the aluminum extrusion alignment tab are required.

Professional Development

This product represents over 18 months of intensive development in collaboration with the Monolith team. The design has been refined through extensive testing protocols and community feedback to deliver the ultimate balance of weight savings, strength, and thermal performance.

The CARBONara CF tube represents the pinnacle of 3D printer motion system upgrades, offering professional-grade performance that enables your printer to achieve its full potential while maintaining the reliability required for production environments.
