This water pump part is a perfect example of why 3D printing is beneficial. The product was no longer available on the market. Therefore, the only option was remodeling it as a 3D‑model and 3D printing it. The new part is printed in Nylon (PA12) using Multi Jet Fusion (MJF) and dyed black.

Our client, CFL (National Association of Luxembourg Railways) wanted to replace the broken cabinet locks of their locomotives.
These locks were not in production anymore. We redesigned the lock and with the advantages of 3D printing technology and more specific SLM (selective laser melting) of aluminium powder, we managed to redesign and produce a small series of the cabinet lock.
Without the advantages of 3D printing, CFL would have been forced to replace the entire cabinet, which means they would have spent more time and money to get the same result.
Nylon PA12 (MJF) with its excellent mechanical properties and detailed surface resolution, is exceptionally versatile and the ideal material for a wide range of applications.
The material has a high impact resistance, due to different geometries it can either be flexible or rigid. The printing technology gives you extensive freedom of design.
By using HP Multi Jet Fusion (MJF) technology, your parts have a higher density, lower porosity and are watertight compared to parts produced with Selective Laser Sintering (SLS). Furthermore the part have homogeneous (isotropic) mechanical properties.
Typical use and our use cases
Complex models, prototypes, architectural models, industrial parts, spare parts, housings
The 3D print process begins by laying down a thin layer (0,08 mm) of nylon powder on a build platform. Next a print head passes the surface while jetting a fusing agent, where the powder should fuse. Also a detailing agent is applied at the boundaries of the parts to produce sharp and smooth edges. In order to fuse the selected areas, fusing lamps pass the surface. The build platform moves down and the next thin layer is being applied.
- Graphite dark grey
- Dyed black
- Flexible or rigid
- Heatproof up to 175°C

- U.V. stabilized and stable to weather
Instead of replacing the whole sub-assembly of an oldtimer car, the broken part was replaced by a 3D printed part.
The part has been replicated with CAD and 3D printed in Nylon.
Material: Nylon (MJF PA12)
Dimensions: 8,5×8,5×10 cm
With 3D printing we can replace the majority of broken parts. Plastic and metal parts can be manufactured with this technology.
Customized 3D printed parts can be adapted to have a unique design or can be reengineered to meet your requirements.

Our client had an issue with his electric sunroof on his car, the metal slider on one side was broken due to material wear.
Since he could not find any replacement parts on the market we managed to reproduce the broken part, our engineering team optimized the part by adding material on certain sections of the part. The material we used was stainless steel, which got polished to work properly.
That shiny piece is chromalised plastic and it was to feeble for its function in a shower. On top of that spare parts are impossible to get.
So for our client we made a spare part and it is a lot tougher than the original part because it has been created in 3D-printed aluminium. The file necessary for printing was created with 3D-Scanning technology and CAD-design.
Voici un exemple qui en illustre tant d’autres. Une petite pièce casse sur un appareil qui n’est plus produit depuis longtemps. Des pièces de rechange sont impossibles à obtenir. Faut-il alors conduire cet appareil à la décharge bien que son remplacement coute peut-être des centaines, voire des milliers.
L’impression 3D permet désormais la production de pièces de rechange. La pièce cassée est mesurée ou scanné pour reconstruire un fichier tridimensionnel. Ce fichier permet alors l’impression d’une (ou plusieurs) nouvelles pièces et ceci dans un grand choix de matériaux, des plastiques aux métaux en passant par les poudres composites multicouleurs.
Dans ce cas précis c’était le bouton du parlophone de la société JNL qui était cassé. Un remplacement aurait couté des milliers d’euros. L’impression était 10 fois moins chère, plus rapide, plus propre, moins bruyante et plus écologique!
