Stronger parts
Continuous reinforcement raises rigidity and durability where short fibers fall short.
Patent pending CCF4 technology
Put strength
where it matters.
CCF4 (continuous carbon fiber fused filament fabrication) places reinforcement at arbitrary orientations. The performance of composites with the freedom and speed of 3D printing.

01 The opportunity
The design freedom of additive. The load paths of composites.
Conventional printed polymers are easy to customize but too weak for many structural roles. Traditional continuous-fiber composites perform, but demand molds, skilled labor, and long lead times.
RIJID closes the gap. CCF4 places continuous reinforcement in any orientation, following the direction of highest stress inside the part.

Oneintegrated workflow
02 CCF4 technology
Reinforcement without restriction.
RIJID combines an FDM platform with continuous carbon fiber placement that is not limited to in-plane reinforcement. Fibers trace the part’s true load paths, unlocking lighter geometries with structural performance conventional prints cannot reach.
- Load-path optimizedReinforce where stress actually travels.
- Part consolidationIntegrate printed structures and composite plates.
- Digital productionMove from design to strong parts without tooling.
03 Better trade-offs
Strong, affordable, customizable. Pick three.
CCF4 brings the structural confidence of continuous-fiber composites into a scalable additive workflow.
Conceptual comparison based on target platform capabilities.
04 Why it matters
More performance.
Less process.
Mold-free
Skip tooling and manual lay-up for faster iteration and lower upfront cost.
Faster production
Compress lead times with a repeatable, digital manufacturing workflow.
Consistent quality
Automated fiber placement supports repeatable performance at higher throughput.
05 First applications
Built for parts that cannot compromise.
RIJID is for teams pushing beyond the limits of conventional polymer printing.
Drones
One integrated airframe.
Replace conventional assemblies of 3D-printed parts and CNC-cut CFRP plates with a single integrated CCF4 component to save weight, increase stiffness and simplify assembly.
Orthotics
Custom fit. Built to last.
Reduce labor and cost versus hand lay-up, while delivering durability beyond state-of-the-art SLS orthoses.
Robotics
Move less mass. Hold more rigidly.
Build lightweight, high-stiffness end effectors for faster, more precise automation.
