About this material

Facilan HT: a copolyester that survives more than PETG does.

Facilan HT is an amorphous copolyester with a high glass transition temperature, made in Haarlem as a higher performance replacement for PET, PETG and similar copolymers. Its own datasheet puts the aim plainly: parts that survive real life.

The heat deflection temperature is 89 °C, and the material is both strong and stiff for its class. That combination lets you drop the infill or thin the walls and still keep a part rigid, which shortens a print without costing you the piece. It comes off the bed with a high gloss. Its own datasheet names machine building, construction and end-use consumer parts as the uses for that combination.

Its raw material carries food contact approval and is not based on Bisphenol A. That approval covers the material we buy, not the object you print, so verify suitability for your own application before you use it that way.

It is an upgrade material rather than a difficult one: it prints a little hotter than PETG, without a heated chamber and without a hardened nozzle.

Printer settings & data sheets

PETG settings, with a bit more heat behind them.

Facilan HT prints in the same regime as PETG, a little hotter, on a warm bed and without a chamber. Nothing about the setup is unusual, which is the point of the material. If the model has no overhangs, set the fan to 0 %: it improves layer bonding and with it the strength of the part. Keep the printer in a room with hardly any draft or temperature fluctuation, and out of direct sunlight.

Keep it dry.

This copolyester is hygroscopic, so prolonged exposure to air and moisture is the thing to avoid. Keep the spool tightly closed in a cool, dry, dark place and put it back in its bag when the printer is idle.

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 Facilan™ HT 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 Facilan™ HT 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 Facilan™ HT.

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.
