IIID Max – High Speed Carbon Fiber PLA+ Filament

IIID Max – High Speed Carbon Fiber PLA+ Filament 1.75mm

Real carbon fiber meets PLA+ in this high-performance composite filament. Short carbon fiber strands reinforced into a PLA+ base deliver exceptional stiffness and a distinctive matte black textured finish — parts look and feel professional right off the build plate. At $35.99 per spool, it's the most accessible way to print lightweight structural components.

Carbon Fiber PLA+ prints as easily as standard PLA but produces parts that are significantly stiffer and lighter. The carbon fiber reinforcement reduces warping and shrinkage, making it one of the most dimensionally accurate filaments available.

Key Specifications

Why Carbon Fiber PLA+?

Standard PLA bends and flexes under load. Carbon fiber reinforcement dramatically increases stiffness — parts resist bending forces that would deform regular PLA. The result is lightweight components with a strength-to-weight ratio approaching aluminum in some geometries. The matte textured surface also hides layer lines naturally, producing professional-looking results without post-processing.

Pro Tips

A hardened steel nozzle is mandatory — carbon fiber particles will destroy a brass nozzle within 1–2 spools. Use 0.5mm or 0.6mm nozzle diameter for best flow. Print at 210–220°C with minimal cooling fan for strongest layer adhesion. The matte finish photographs beautifully for product listings without any glare or reflection issues.

Best Applications

Drone frames, RC vehicle chassis, camera mounts, tool handles, stiff brackets, lightweight structural components, engineering prototypes, laptop stands, and any application where rigidity and low weight are priorities.
