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.

Spare part for electric sunroof

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.

Stronger than the original: aluminium

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.

Wenn’s nicht gefällt, ersetz es durch deine eigene Idee

Die Stromschienen an der Decke der neuen Wohnung haben Endkappen, die weder dem Bauherrn, noch dem Architekten gefallen. Der Hersteller der Stromschienen hat keine passende Lösung im Programm.

Also haben die Architekten von arend + thill architecture selbst eine passende, stilistisch klare, Endkappe in 3D gezeichnet und von 3dprint.lu in der notwendigen Stückzahl produzieren lassen.
