FDM 3D printing service

Parts that only exist because they were printed

Enclosed manifolds, undercut channels, vibration-tuned lattices — geometry no mill or mould can reach. Three real projects, with the engineering behind each one.

Case studies

Three projects, three reasons printing won

3D-printed PA6-CF vortex gripper body with a brass G 1/8-inch fitting and external spiral air channels

Engineering problem · FDM, no moving parts

VG-90 non-contact vortex gripper

Lifting 110 °C glass bottles straight off the annealing lehr without touching them — one printed part, no moving parts.

Holding force9.5 N, non-contact

3D-printed vibration-isolating sensor mount with an X-braced truss column and a copper-lined M20 boss

Problem · FDM, no moving parts

Vibration-isolating mount for a pressure sensor

A pressure sensor shaking itself apart on a pump housing — isolated where it sits, instead of moved somewhere quieter.

Materials

3D printing materials: three tiers, matched to the job

Standard — PLA, PETG

Prototypes, design models, everyday parts. Biodegradable (PLA) or tough and chemically resistant (PETG).

BlackBlueGoldGreenGreyMarbleOrangeRedSilverTransparentWhiteYellow

Technical — ABS, ASA, TPU95

Resistant to mechanical load, heat and UV (ASA). Flexible TPU for seals and damping elements.

BlackBlueGreenGreyRedWhiteYellow

Engineering — PC, PC-ABS, PC-PBT, PC-FR, PA6, PA-CF, PA-GF, PAHT-CF, PPA-CF, PPA-GF, PET-CF, PPS-CF

Carbon- and glass-filled composites, extremely stiff polycarbonates, high-strength nylons, and high-performance polymers such as PPS-CF. Flame-retardant grade available (PC-FR).

How it works

From file to shipment

  1. 01

    Upload

    Send your STL, STEP, or OBJ file and choose the material and layer height you need.

  2. 02

    Quote

    An engineer reviews the geometry and sends a fixed-price offer, usually within one working day.

  3. 03

    Print

    Once you accept and pay, your parts go into the queue on the printer matched to your material.

  4. 04

    Ship

    Finished parts are inspected, packed, and shipped with tracking — typically 2–5 working days after payment.

Questions

3D printing — frequently asked questions

Can I order a single part?

Yes. A batch size of one is our normal order, not an exception — most of what we print is one to ten pieces.

How fast can you print and ship?

Typical lead time is 2–5 working days after payment, plus tracked shipping across the EU. If you have a hard deadline, state it in the request — express lead times are quoted explicitly, not implied.

Which materials can you print?

Engineering polymers from PLA to PPS-CF, in three tiers: standard (PLA, PETG), technical (ABS, ASA, TPU95) and engineering (PC, PC-ABS, PA6, PA-CF, PA-GF, PAHT-CF, PPA-CF, PET-CF, PPS-CF and others). A flame-retardant grade (PC-FR) is available.

Do you print carbon-fibre nylon?

Yes — PA-CF, PAHT-CF and PPA-CF are among our most-used materials for functional parts, jigs and end-of-arm tooling.

Which files do you accept?

STL, STEP, OBJ · up to 150 MB

Do you sign NDAs?

Confidentiality is our default — customer files and specifications are never published or reused, as our Terms state. We sign NDAs on request.

How do I get a quote?

Upload your model and choose the material and layer height. An engineer reviews the geometry and sends a fixed price — usually within one working day.

Have a part that needs printing, not moulding?

Upload your model and get a fixed-price offer from an engineer, not a calculator.
