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

01

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.

02

Fibre routing design

Our engineers specify isotropic, concentric or unidirectional fibre paths and reinforcement density per layer.

03

Print on Markforged

Onyx (carbon-filled nylon) base extrudes alongside continuous carbon, fibreglass or Kevlar — fused at every layer.

04

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.

Materials

Markforged composite system

Onyx base material with four reinforcement options — chosen per part to match load, environment and budget.

Onyx (Carbon-Filled Nylon)

Base

The default base material. Tough, dimensionally stable carbon-filled nylon — already stronger than ABS before continuous reinforcement.

Continuous Carbon Fibre

Reinforce

Aerospace-grade carbon fibre tow routed through Onyx for maximum stiffness-to-weight in load-bearing parts.

Continuous Fibreglass

Reinforce

Lower-cost reinforcement with similar tensile strength to carbon fibre but lower stiffness — ideal for higher-elongation parts.

Continuous Kevlar

Reinforce

Aramid reinforcement for impact-resistant parts that need to bend and recover rather than fracture.

High-Strength HSHT Fibreglass

Heat

Heat-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.

FAQ

Frequently asked questions

A properly-reinforced Markforged carbon part achieves tensile strength around 800 MPa along the fibre direction — comparable to 6061-T6 aluminium. Stiffness is similar; weight is roughly 60% of aluminium.
