Luvocom® 3F PAHT 9825 NT Filament.

A high-temperature polyamide that takes about four times longer than PA6 to soak up moisture, and saturates lower. That is what keeps a printed part dimensionally honest, and it runs on an open printer with no chamber. read further

About this material

Luvocom 3F PAHT 9825: a high-temperature nylon without the nylon problems.

Luvocom 3F PAHT 9825 NT is an unreinforced high-temperature polyamide from the LUVOCOM 3F range. It is the approachable end of the engineering-polymer class: a serious nylon aimed at end-use parts, functional prototypes and jigs, tools and fixtures, that still prints on a conventional FFF machine.

The reason to choose it over a standard nylon is moisture. Water uptake takes roughly four times longer to reach saturation than unmodified PA6, and it saturates at a lower point. Its own datasheet puts the consequence plainly: little influence from moisture and temperature on dimensional stability and on electrical properties. A nylon part that does not move is a different proposition from one that does.

Mechanically it is strong for an unreinforced grade, and in the unnotched Charpy test it does not break at all. It prints with low warping and good layer bonding, and it needs no heated chamber.

This is the natural, unreinforced grade. If you need carbon-fibre stiffness or a flame-retardant rating, those are separate grades in the same family.

Printer settings & data sheets

A serious polyamide that still runs on an open printer.

This grade prints on conventional FFF and FDM systems, with a hot nozzle and a warm bed but no heated chamber. Layer bonding is good and warping is low for a polyamide, which is much of why this grade exists.

Dry it first.

Like any polyamide it takes up moisture from the air, so pre-dry the filament at 100 °C for four to six hours, or at 80 °C for twelve. Seal the spool between jobs and keep it dry.

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 9825 NT 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 9825 NT 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 9825 NT.

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.
