KRATIR PP CF: Carbon Fiber Polypropylene Filament (1.75mm & 2.85mm) | 3D3 Tech
Share
Light. Strong. Unbreakable Under Pressure. — KRATIR PP CF Explained
Most engineers hit a wall with standard polypropylene: it's chemically tough, but it's too soft and too flexible for load-bearing or precision parts. KRATIR PP CF from Tectonic-3D solves that problem by reinforcing PP with carbon fiber, creating a filament that's lightweight enough for drone frames and rigid enough for industrial tooling — without giving up the chemical resistance that made polypropylene useful in the first place.
It's available now at 3D3 Technology in both 1.75mm and 2.85mm diameters, ready to ship anywhere in the USA.
What Makes KRATIR PP CF Different
Ultra-Lightweight
A density of just 1.07 g/cm³ keeps printed parts light without sacrificing structural performance — ideal anywhere weight is the enemy.
High Rigidity
A 13 GPa tensile modulus delivers serious stiffness, so parts hold their shape and resist deformation under real working loads.
High-Speed Printing
Engineered for print speeds up to 250 mm/s, so production teams can turn out parts faster without compromising quality.
Chemical Resistance
Inherits polypropylene's excellent resistance to oils, solvents, and industrial chemicals — built for harsh shop-floor environments.
ESD Safe
Electrostatic discharge safe per DIN EN 62631-3-2, making it a natural fit for electronics housings and components near sensitive circuitry.
Premium Surface Finish
Prints with a smooth, matte black finish straight off the printer — professional-looking parts with no post-processing required.
"Tectonic 3D's KRATIR PP-CF completely redefined what's possible in lightweight UAV manufacturing. It's the first filament that allowed us to print ultra-thin, single-wall structures with the strength and thermal resilience needed for real-world performance — and the surface finish is perfect straight off the printer." George Petrov, Founder at Nomadium Robotics

Real-World Manufacturing Applications
KRATIR PP CF isn't a novelty material — it's already replacing aluminum and injection-molded specific applications. Here's where it earns its keep:
🛸 Lightweight UAV & Drone Frames
High stiffness-to-weight ratio supports ultra-thin, single-wall structures for airframes and components where every gram affects flight time.
🔧 Jigs, Fixtures & Tooling
Rigid, chemically resistant, and dimensionally stable — ideal for shop-floor fixtures that need to survive oils, solvents, and daily handling.
🔌 Electronics Housings
ESD-safe properties protect sensitive components from static discharge, making it a strong choice for enclosures near PCBs and connectors.
🧴 Chemical-Exposed Components
Tanks, fittings, and parts that contact solvents or industrial fluids benefit from polypropylene's native chemical resistance, reinforced for rigidity.
🏭 Rapid Production Runs
250 mm/s print speeds mean shorter cycle times for batches of functional parts — less machine time per unit, faster turnaround for customers.
🚗 Automotive Brackets & Clips
Lightweight, stiff, and resistant to automotive fluids — a practical alternative to metal brackets where weight reduction matters.
Why It Matters for Your Workflow
Standard PP is too soft for structural work. Standard carbon-fiber nylons absorb moisture and warp. KRATIR PP CF splits the difference: the chemical resistance and low weight of polypropylene, with the stiffness of a carbon-reinforced engineering material — printed at speeds that keep production schedules realistic.
