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.
On Nov 2017 a client came to us with a quite short list of requirements of a high chair for children. The concept should be transportable, lightweight, compact when dissembled and suitable for babies and toddlers. There are two kinds of travel high chairs on the market: those who need to be fixed on a chair or table and those who can stand by themselves. The first ones have a more or less decent size but do not fit all chairs and tables. The second ones fit every situation but are mostly clumsy and heavy. Both of them can only be used by children who are able to sit by themselves. Our focus was to create a high chair which would allow families to be flexible in every situation such as visiting restaurants or other family members who are not equipped with a sitting solution for small children or babies.
The concept is the first one to stand by itself and have a decent size once it is dissembled. It even comes with a foldable Baby-Inlay, so that it can be used for newborns and toddlers by setting them into a healthy laying position. The telescopic legs can be pulled out to their maximum length to achieve the height of a common table, although it can be fixed in every other preferable height. Quick clamps allow a fast installation of the high chair. The foldable Baby-Inlay can be put into the sitting area or, when not used, folded together and fixed under the seat.
According to feedbacks from our first users the travel high chair is a good allrounder when it comes to having a sitting solution for children. It’s ability to be a stand alone high chair does give you the opportunity to install/unfold it in situations you may need it. You can even use it when the chair is in it’s lowest position. The sitting area dimensions are a bit bigger than in common high chairs, it gives small children more freedom to play around while sitting, also it is crucial for the needed space of the inlay for newborns.
The 3D model of the cells has been created based on drawings and microscopic pictures.
After the render of the 3D model has been approved by the client, the top and bottom layer have been 3D printed in nylon (MJF PA12) and painted by hand to reproduce the original cells as accurate as possible.
Placed in a custom made acrylic glass frame and filled
with jelly the model was ready to be presented on the LIST TECH DAY 2019.
Mostly 3D printed materials! The individual layers of
additive manufacturing can be seen on the metal parts. Head and spar are made
of sintered PA12 Nylon which was then colored in black. All internal cylinders
were made of brass. The metal band was formed from 420SBR, a mixture of stainless
steel and bronze, then black coated.
To celebrate the Grand Duke’s
Official Birthday we did some amazing X-models for the Ministry of Foreign and
European Affairs. Known from the new signature and slogan of Luxembourg
“Let’s make it happen“.
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.
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
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.
The bird from the animated short “Luxembourg Let’s make it happen – by Oscar-winning director Laurent Witz-” symbolizes how an idea takes flight and conquers the world through collaboration, creativity and perseverance. Openness, dynamism and reliability: Luxembourg’s core values are the driving forces behind new ideas and partnerships, making the Grand Duchy the ideal location to bring your ideas to life.
This project has been realized in collaboration with the Ministry of the Economy and the Ministry of Foreign and European Affairs.
Due to the local manufacturing of every single piece, we could add the „Made in Luxembourg“ label to the packaging. The bird sculpture was printed in nylon (MJF PA12) and post processed with a carbon finish.
