Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

The breakthrough
One nozzle. Two filaments. Infinite tuning.
Most “carbon fibre” printers extrude chopped filler that barely lifts strength. The FibreSeeker 3 co-extrudes continuous fibre and polymer in a single patented head — so you dial the fibre-to-plastic ratio up or down, mid-print, exactly where the load is.
Patented dual-nozzle CFC head
Composite Fibre Co-extrusion (CFC) reinforces parts with unbroken fibre paths — eliminating brittleness and the dependence on CNC machining.

Continuous fibre vs. chopped filler
Chopped “CF” filaments are mostly marketing — short fibres that add stiffness but little real strength. Continuous fibre runs unbroken through the part, carrying load like rebar in concrete.
Indicative tensile strength of printed test specimens. Figures from the manufacturer; real-world results depend on geometry and fibre routing.
Why it pays off
Industrial composite performance, desktop economics.
Replace machined metal
Print load-bearing brackets, jigs and fixtures in carbon fibre — a fraction of the weight, overnight, with no machine shop.
~70% cheaper continuous fibre
FibreSeek’s own X-CCF carbon fibre runs about 70% below comparable continuous-fibre spools, so the cost per part stays low.

Why buy it from Additive Plus
A machine is easy to ship. Getting parts out of it isn’t.
We’re a California-based full-stack additive partner — we sell what we’d run, support what we sell, and engineer what isn’t on the shelf. With the FibreSeeker 3 you also get the team behind it.
◷
US onboarding, not a forum
Setup and first-print guidance from US engineers — get productive on continuous-fibre fast instead of unboxing novel tech alone.
↻
Warranty handled here
1-year manufacturer warranty managed locally — no shipping a 32 kg machine overseas to get it serviced.
⊞
Fibre & spares, sorted
Continuous carbon and glass fibre, matrices, nozzles and spares sourced through us so the printer keeps earning.
✎
DfAM & fibre routing
Send us a part and we’ll show where continuous fibre actually pays off — so you print load-bearing parts, not paperweights.
◆
Price & slot locked
Place your order and your October 2026 build slot and price are locked — no waiting on a quote while demand keeps climbing.

FAQ
Questions, answered.
How is this different from a carbon-fibre filament printer? +
Carbon-fibre filaments contain short chopped fibres that add stiffness but little real strength. The FibreSeeker 3 lays down continuous fibre — unbroken strands routed through the part like rebar — reaching up to 900 MPa, far beyond what chopped-fibre plastics can do. Want help deciding if it fits your parts? Talk to an engineer.
What materials can it print? +
FFF plastics: PLA, PETG, PC, PA, PACF and PETGF. Continuous fibre: X-CCF (carbon) and X-CGF (glass). The dual head co-extrudes fibre and plastic together so you control reinforcement section by section.
How do I get in the queue — and do I pay now? +
Just place your order — it reserves your spot in the October 2026 batch and locks your price. Pay by card, or choose “Request an invoice” at checkout for a PO or net terms. You don’t need to call us to buy. Prefer a walkthrough or onboarding before you commit? Talk to an engineer first — but it’s optional.
Do I need composite experience to run it? +
No. The slicer auto-optimizes fibre routing from presets, and Additive Plus provides onboarding plus DfAM guidance on your first parts. Choose a mode, load the file, print.
What’s the lead time? +
Demand is high and the order book is filling. The next available batch ships October 2026 — place your order now to lock an October slot and your price before it rolls to the next batch. Pay by card or request an invoice at checkout.
Why buy from Additive Plus instead of direct? +
You get a US-based engineering partner: stocked materials and spares, sub-24h support, DfAM and fibre-routing help, warranty handling and onboarding — so the machine actually produces parts, fast.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is a continuous fibre 3D printer and how does FibreSeeker 3 differ from standard FDM printers?
A continuous fibre 3D printer embeds continuous reinforcement strands into the print, unlike standard FDM which uses only thermoplastics or short fibres. FibreSeeker 3 produces structural composite parts with significantly higher strength.
What materials can be used in the FibreSeeker 3 continuous fibre 3D printer?
The system supports PLA, PETG, PC, nylon, and reinforced materials, along with continuous carbon and glass fibres for structural applications.
Can the FibreSeeker 3 replace metal parts in engineering applications?
Yes, for many applications requiring high strength-to-weight ratio, FibreSeeker 3 can replace metal components, especially in aerospace, robotics, and automotive use cases.
What industries benefit most from continuous fibre 3D printing?
Aerospace, automotive, robotics, and industrial manufacturing benefit the most due to the need for lightweight, high-strength parts.
Is the FibreSeeker 3 suitable for production or only prototyping?
It is suitable for both. The printer enables functional prototyping and small-batch production of end-use composite parts.
