Automotive & Aerospace : two key sectors for metallic additive manufacturing
In addition to the medical sector, market reports, corporate reports and even media reports reveal that the aerospace and automotive sectors are currently the most demanding sectors in the additive manufacturing market.
Surprisingly (or not), of all the technologies used in these industries, the Wohlers Report 2018, announced a “dramatic rise in metal additive manufacturing and overall industry growth of 21%».
The growth of such technology, its impact in these two sectors still raise some questions regarding its potential, its use and its limits within the industry. That’s the issue we decided to tackle this month with the participation of Benjamin Denayer (Sirris), Dr. Martin McMahon (Renishaw), Kay-O Kissling (3D Systems for Aerospace), Michael Sattler (3D Systems for Automotive), Delphine Carponcin (Airbus) and Frank Götzke (Bugatti).
1.Metal additive manufacturing (AM) in a few words …
Metallic additive manufacturing is based on the use of two main technologies: Powder Bed Fusion process and Directed Energy Deposition (DED). Simply put, in the first case, an electron beam or simply a laser will melt or sinter a narrow layer of powder. The second layer will then be deposited and melted or sintered onto the former layer.
In the case of Directed Energy Deposition (DED) on the other hand, the laser used will melt metal powder brought into the laser spot and this melted material will be projected on the object surface. Once melted, the powdery material forms a layer that will fuse with the substrate.
What type of metal additive manufacturing technology is most widely used in the automotive and aeronautics sectors?
For Benjamin Denayer, Senior Business Developer Additive Manufacturing at Sirris, LBM (laser-based manufacturing technology) is the most widely used type in both industries…. Read the rest of the dossier
