ASA Filament.
Print functional parts that stay out in the sun, rain, and heat far longer than ABS before they fade or turn brittle. This material delivers the toughness and printability of ABS, for components that live outdoors. read further
- UV / Weather resistant
- High impact strength
- Good interlayer adhesion

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 ASA you can focus on your design, not your material.
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 ASA 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 on the production line, before it ever leaves the machine.
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 ASA.
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.
