Product development and functional prototype of a high chair for children

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.

Rescaled 3D Model of a cell for research

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.

1st place in the category Product Design for the N9 tobacco pipe!

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.

High detail metal figures

Impressive results with cutting edge Binder Jetting Technology on 3D printed metal figures.

First scanned in an Artec Shapify Booth to receive the 3D file, then printed in stainless steel 316L.

The printed metal figure, 4 cm high, was sandblasted to get a smooth surface finish (Ra 3 µm).

Material introduction: Nylon PA12 MJF

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

Technology

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.

Short overview of our available materials

3D printed part for oldtimer

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.

Small projects 2018

Customized 3D printed parts can be adapted to have a unique design or can be reengineered to meet your requirements.

Une pièce de rechange d’origine n’était plus disponible, mais avec la pièce reconstruite imprimée en 3D, l’auvent pouvait être réparée.

3D gedréckte Stécker kënnen no de Virstellunge vum Client oder de mechanesche Viraussetzungen adaptéiert ginn.

Inspiring Luxembourg – Collector’s Edition

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.

Media Award 2018 Trophy 

SONY DSC

In order to match the previous trophies of the Media Awards we didn’t change the overall shape, but its’ uniqueness came from the fact that the creation was only possible using Additive Manufacturing.

After several prototypes the decision was taken to implement a lattice structure, which is usually placed into industrial parts for reducing weight and material cost.

The trophy was printed in Nylon PA12 with the latest HP MJF 3D Printer, afterwards the parts were black dyed. The acrylic glass inlet was printed from the backside and fitted seamlessly in the front of the trophy. Milled anodized aluminum plates in gold, silver, bronze and red were mounted to represent the ranking.

The challenge of implementing additive manufacturing and different materials in one object resulted in a unique trophy for the winners of the Media Awards 2018.
