About this material

Luvocom 3F PAHT CF 9742: carbon-fibre stiffness at 200 °C.

Luvocom 3F PAHT CF 9742 BK is a high-temperature polyamide reinforced with carbon fibres, supplied in black. It is aimed at industrial end-use parts and at serial production where printed parts have to meet the strength expectations of injection moulding.

The numbers are what carry it: exceptional stiffness and strength for a polyamide, a heat distortion temperature of 200 °C and continuous service at 150 °C. It also stays put. Mould shrinkage is close to nothing, thermal expansion is low, and water absorption is under 0.3%, so a part comes out to size and stays there.

It has high Z-strength, meaning strength in all directions rather than only in the print plane. That is the difference between a good-looking print and a functional or structural part.

For all that, it prints with minimal warping and improved layer adhesion on an open printer, without a heated chamber.

Printer settings & data sheets

Carbon fibres, so bring a nozzle that can take them.

This filament is carbon-filled and abrasive. A brass nozzle will wear out on it and take your dimensional accuracy with it, so use an abrasion-resistant one, and keep the layer thickness above 0.2 mm. Beyond that it prints hot on a warm bed, on an open machine.

Keep it dry.

Polyamides take up moisture from the air and it shows in the print. Seal the spool between jobs and store it somewhere dry, and dry it before a critical print if it has been standing open.

Measurements & tolerance

Precision-engineered consistency.

Consistent prints start with a uniform filament shape. We continuously monitor diameter and roundness during production. When filament varies in size or loses its round profile, material flow becomes erratic. This causes under-extrusion and weak layer bonds.

Our manufacturing process keeps the cross-section stable across the full spool. Your printer receives a steady volume of material without pressure drops in the nozzle. You get predictable extrusion on every job, so with Luvocom® 3F PAHT CF 9742 BK you can focus on your design, not your material.

The production process

Sealed at the source. Never touched by water.*

Unlike manufacturers who cool filament in a water bath, our filament never touches water during production. Moisture inside the material creates bubbles and weakens layer bonding during printing. Water-free production keeps extrusion consistent and bubble-free.

Sealed and ready to print.
We produce on demand. Every spool is vacuum-sealed immediately after extrusion, so it reaches you dry. This process keeps every spool of Luvocom® 3F PAHT CF 9742 BK ready to print out of the box.

* At times of high demand, and for some variants, production may run on a conventional water-cooled line. Contact us before ordering if you require material produced with our water-free process.

Vacuum-sealed filament spool, straight off the extrusion line

Vacuum-sealed on the production line, before it ever leaves the machine.

Traceability & quality assurance

Precision you can track. From pellet to part.

We produce every spool on demand in our own facility. This gives us direct oversight that mass-produced stock lacks. Your spool comes from a fresh, identifiable batch rather than long-term warehouse inventory. We document the production trail for every run.

Documented, not just shipped.
We keep the production logs for every batch we make. On request, we link a Certificate of Analysis and Technical Data Sheet to your specific batch. You get clear data for your spool of Luvocom® 3F PAHT CF 9742 BK.

About 3D4M

Dutch engineering for parts that define the future.

At 3D4M, we develop and manufacture high-performance thermoplastic filaments for demanding applications across aerospace, defence, semiconductor, automotive, medical research, and industrial manufacturing. We work with engineers, researchers, and manufacturers who need materials that go beyond standard specifications.

Our engineering starts with the machines themselves. We design and build our own extrusion lines around our patented extrusion process, combining material expertise with technology developed in-house. For moisture-sensitive polymers, our air-cooling technology offers a water-free cooling option, allowing us to tailor the production process to the material.

Our production facility is built on a single, uncompromising principle: control. From our extrusion technology to precise diameter monitoring and vacuum-sealed packaging, we control every stage to deliver consistent filament with batch traceability.

Trusted by global leaders
Supporting over 100 universities alongside global industry leaders, we have become a trusted partner to advanced research labs and manufacturers worldwide. We bring together material expertise and Dutch engineering to help turn ambitious ideas into reliable, high-performance parts.
