3.5KG Carbon Fiber Reinforced Series | Industrial Bulk Production

Scale your professional manufacturing with our 3.5KG Carbon Fiber Reinforced industrial spools. Engineered for high-volume output and long-duration prints, this bulk format provides the structural benefits of premium milled carbon fiber with the cost-efficiency and reliability required for true production environments.

By using a single 3.5KG spool, you eliminate the risk of mid-print filament swaps and ensure total color and texture consistency across your largest industrial assemblies.

Bulk Performance Highlights:

• Continuous High-Volume Printing: The 3.5KG (7.7 lbs) capacity is ideal for massive parts, such as automotive body panels, protective industrial housings, and large-scale architectural mock-ups.

• Eliminate Part Failure: The addition of carbon fiber greatly reduces warping and shrinkage. This allows you to print large-format, flat-surfaced parts with confidence that they will remain dimensionally accurate.

• Stealth Technical Finish: Delivers a deep black, non-transparent finish (HEX #3B3B3B) with a sophisticated micro-texture that effectively hides layer lines for a "molded" look.

• Stringing Resistance: The specialized fiber load significantly reduces "angel hair" stringing, meaning your large parts require minimal post-processing.

Technical Specifications:

• Material: Carbon Fiber Reinforced (Available in PLA or PETG PRO bases)

• Weight: 3.5KG (7.7 lbs)

• Color: Deep Black (Textured Matte)

• Reinforcement: Premium Milled Carbon Fiber (USA Sourced)

• Tolerance: ± 0.02mm or better

• Nozzle Requirement: Hardened Steel (0.4mm or larger recommended)

Industrial Applications:

• Large-Scale Jigs & Fixtures: Create rigid, non-flexing workshop tools that can withstand daily industrial use.

• Automotive Prototypes: Perfect for full-scale interior components or under-hood enclosures that require a professional, factory-grade aesthetic.

• Aerospace & Drone Frames: High stiffness-to-weight ratio parts that demand zero-warp precision.

• End-Use Housings: Durable, impact-resistant enclosures for electronics and machinery that need to look as good as they perform.

Pro Printing Tip for 3.5KG Spools:

When running these larger spools, ensure your spool holder or floor-rack is positioned to allow a straight path to the extruder. This prevents unnecessary tension on the feed motor during long-format prints.
