The coronavirus pandemic causes a shortage on personal protective equipment for health care professionals.
With the help of our Luxembourgish industrial partners, such as GCL Technologies and Lettrage Reding, we decided to step in and support our local authorities in fighting the COVID-19.
The provided face shields are designed to protect the health care professionals, who treat the patients in critical condition. The shield is fixed on the forehead, protects the entire face and keeps the caregivers safe. This is an important measure to safeguard the capacity of the health care system.
The face shields, designed by Prusa, are being 3D printed in Nylon (PA12) using Multi Jet Fusion (MJF) Technology. As a result, our face shields can be sterilized without losing its shape, flexibility or function.
The face shields were donated to the Luxembourgish Ministry of Health and Army.
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.
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.
Für das Gemeindesyndikat Distribution d’eau des Ardennes haben wir das Modell eines geplanten Trinkwasserbehälters erstellt.
Anhand dieses Modells können komplexe Verläufe und Bestimmungen der verschiedenen Rohrleitungen anschaulich dargestellt werden. Verschiedenfarbige Pfeile und Symbole sorgen dafür, dass Zufuhr, Versorgung, Entleerung, Überlauf, Belüftung und Pumpen sofort erkennbar sind.
Erstellt wurde das Modell in Nylon im Maßstab 1/100
