Ist das so fest wie Carbon-Laminat?

Nein. Es handelt sich um kurze Fasern im Kunststoff, nicht um Endlosfasern. Die Steifigkeit steigt deutlich, die Festigkeit moderat. Für Laminat-Anwendungen ist es kein Ersatz.

Ist ein Carbon-Teil zwischen den Lagen schwächer?

Ja, wie jedes FDM-Teil. Die Fasern verstärken vor allem in der Ebene. Deshalb richten wir das Teil nach der Hauptlast aus.

Warum kostet Carbon mehr?

Das Filament ist teurer, es braucht gehärtete Düsen und sorgfältige Trocknung. Im Vergleich zu einem gefrästen Aluminiumteil ist es trotzdem meist günstiger und schneller.

Wie sieht die Oberfläche aus?

Matt, leicht strukturiert und mit wenig sichtbaren Lagen. Für Sichtteile ist das oft ein Vorteil.

Carbon fibre filled 3D printed parts

Short fibre filled polyamides are stiffer, warp less and look matte and clean. For fixtures, grippers and machine parts they are often the best choice in FDM.

Hardened nozzles, dried material

Typical carbon parts

When stiffness and weight matter but aluminium is too expensive or too slow.

Gripper fingers

Lightweight jaws for robots and pick and place, quick to adapt.

Assembly fixtures

Nests that do not deform in operation.

Brackets and consoles

Camera mounts, sensor consoles and support arms.

Replacement for small aluminium parts

Where weight and lead time matter more than maximum strength.

Suitable materials

PA12-CF as the all-rounder, PA6-CF and PPA-CF for more heat and strength, PETG-CF and ASA-CF as cheaper options.

When carbon really pays off

Many order carbon because it sounds like performance. We first ask what problem needs solving. If the part bends too much, carbon is the right answer. If it breaks on impact, unfilled PA12 or PC is often better because fibres reduce toughness.

A big practical advantage is dimensional stability. The fibres reduce shrinkage, so the part warps less. For long, flat fixtures that is often the real reason for PA12-CF.

Carbon printing FAQ

Is it as strong as carbon laminate?: No. These are short fibres in plastic, not continuous fibres. Stiffness rises clearly, strength moderately. It does not replace laminate.
Is a carbon part weaker between layers?: Yes, like every FDM part. The fibres reinforce mainly in plane. That is why we orient the part to the main load.
Why does carbon cost more?: The filament is more expensive, it needs hardened nozzles and careful drying. Compared with a machined aluminium part it is still usually cheaper and faster.
What does the surface look like?: Matte, slightly textured and with few visible layers. For visible parts this is often an advantage.
