Continuous Carbon Fibre 3D Printing — Metal-Replacement Strength
Forge Labs runs a fleet of Markforged systems printing continuous carbon fibre, fibreglass and Kevlar reinforcement through carbon-filled nylon — producing structural parts that genuinely replace machined aluminium at a fraction of the lead time and cost.

Why Forge Labs
Why engineers choose CCF over machined aluminium
Markforged continuous reinforcement gives you metal-grade structural performance with additive economics.
Stronger Than Aluminium
Continuous carbon fibre reinforced parts achieve stiffness comparable to 6061-T6 aluminium at a fraction of the weight.
Metal-Replacement Capable
Brackets, fixtures and load-bearing parts previously machined from aluminium can now be 3D printed in days, not weeks.
Markforged Onyx Matrix
Onyx (carbon-filled nylon) base material with continuous carbon fibre strands routed exactly where load is highest.
Tunable Stiffness
Fibre routing, fill density and reinforcement layers are specified per-part — you only pay for the strength you actually need.
Fast Iteration
Test a load-bearing prototype in 48 hours instead of 4 weeks of CNC tooling and machining.
Our Workflow
How a CCF job is engineered
Send the part & load case
Upload your CAD plus a description of the load — direction, magnitude, frequency. We'll engineer the fibre layup to match.
Fibre routing design
Our engineers specify isotropic, concentric or unidirectional fibre paths and reinforcement density per layer.
Print on Markforged
Onyx (carbon-filled nylon) base extrudes alongside continuous carbon, fibreglass or Kevlar — fused at every layer.
Inspect, finish, dispatch
Parts are dimensionally checked, post-cured if specified, and shipped with a documented fibre layup spec.

What we deliver
Continuous fibre reinforcement, engineered per part
Onyx base · Carbon / glass / Kevlar routing · Documented load capacity
Continuous carbon fibre 3D printing is fundamentally different from chopped-fibre filament. A continuous strand of aerospace-grade fibre is laid down between layers of Onyx (carbon-filled nylon), bonded by the matrix, and routed exactly where stress is highest. The result is an engineered composite part — not a generic printed plastic — with strength-to-weight that rivals milled aluminium and lead times measured in days, not weeks.

Learn more ↗Materials
Markforged composite system
Onyx base material with four reinforcement options — chosen per part to match load, environment and budget.
Onyx (Carbon-Filled Nylon)
BaseThe default base material. Tough, dimensionally stable carbon-filled nylon — already stronger than ABS before continuous reinforcement.
Continuous Carbon Fibre
ReinforceAerospace-grade carbon fibre tow routed through Onyx for maximum stiffness-to-weight in load-bearing parts.
Continuous Fibreglass
ReinforceLower-cost reinforcement with similar tensile strength to carbon fibre but lower stiffness — ideal for higher-elongation parts.
Continuous Kevlar
ReinforceAramid reinforcement for impact-resistant parts that need to bend and recover rather than fracture.
High-Strength HSHT Fibreglass
HeatHeat-stable fibreglass that retains stiffness up to ~150 °C — for under-bonnet and heated-tooling applications.
Industries we serve
Where continuous carbon fibre earns its keep
Structural parts where stiffness matters, weight matters, and waiting four weeks for a CNC slot doesn't work.
UAV & Drone Frames
Lightweight load-bearing chassis, payload mounts and propeller guards stiff enough to fly serious payloads.
Motorsport Brackets
Sub-aluminium-weight brackets, mounts and ducting for racing applications where every gram counts.
Manufacturing Fixtures
Robot end-effectors, work-holding jigs and inspection fixtures with metal-grade stiffness and zero tooling cost.
Defence Prototypes
Confidential structural prototypes printed under NDA — fast iteration for weapon mounts, equipment housings and field-deployable kit.
Mining Spares
Replacement brackets and handles for remote-site equipment when OEM lead time is months and downtime is unacceptable.
Research Equipment
Custom rigs, sensor mounts and one-off test fixtures for universities and R&D labs.
