Standardization of 3D Printing: ASTM Awards Contract to Fraunhofer ILT

The Fraunhofer Institute for Laser Technology ILT has received an award for decades of development in the field of additive manufacturing: The Aachen-based institute won a competition conducted by ASTM International and is now working on a project towards standardization of machine condition monitoring in laser beam powder bed fusion (LB-PBF). It is focusing on selecting and qualifying imaging sensor technology that can be used to specifically monitor the condition of LB-PBF systems. Finally, the institute will derive cost-reducing recommendations for end users from these data.

Mobility of the future: power electronics with hybrid circuit boards instead of ceramics

Scientists at the Fraunhofer Institute for Laser Technology ILT, in collaboration with project partners, have succeeded in developing a novel industrial manufacturing process, one that makes it possible to use low-cost FR4 circuit board substrates in power electronics, for example in electric motors. Compared to conventional power electronics made of ceramics, the so-called hybrid printed circuit boards are not only much more versatile, but also up to 20 times cheaper. This could close a gap in the market in the medium term and, thus, make an important contribution to the mobility of the future.

Controlling 100 lasers automatically via the cloud

In the Cluster of Excellence “Internet of Production” (IoP), 200 scientists at RWTH Aachen University in cooperation with Fraunhofer ILT have set up a data center for controlling and monitoring industrial processes. The concept for this is based on a project for controlling laser systems developed at the Fraunhofer Institute for Laser Technology ILT and uses the open source software Kubernetes. A corresponding system has been running successfully at the institute for two years, and with it the institute can automatically and remotely install the software for new lasers in just a few minutes.

Research and development for your innovations – New competence area management at Fraunhofer ILT in the field of Additive Manufacturing#

News / July 2021

In industry, additive laser processes are being applied in a continuously broadening spectrum. This situation is pushing forward research and development in Additive Manufacturing and enabling innovations with a far-reaching impact.

Since the mid-1990s, the Fraunhofer Institute for Laser Technology ILT has been advancing Additive Manufacturing (AM), for example Laser Powder Bed Fusion (LPBF) or powder or wire feed-based Laser Material Deposition (LMD). That Fraunhofer ILT has established two new competence areas for AM reflects its growing importance at the Aachen Institute: As of June 2021, Jasmin Saewe will take over as head of the “Laser Powder Bed Fusion” competence area. Dr. Thomas Schopphoven will be responsible for managing the “Laser Material Deposition” competence area from June 2021.

Competence Area Manager “Laser Material Deposition”
Jasmin Saewe M.Sc.
Competence Area Manager “Laser Powder Bed Fusion”

Laser Powder Bed Fusion makes it possible to manufacture complex functional components in a resource-efficient and economical way. Since it has high geometric flexibility in the production of metallic components, the process offers a number of advantages compared to conventional manufacturing techniques and is suitable for applications in various industries, such as turbo machinery, aerospace, automotive and medical technology. Fraunhofer ILT focuses on developing innovative geometry-adapted exposure concepts and systems engineering as well as function-adapted application components and their industrial process chains. The institute’s extensive equipment consists of different commercial systems and self-developed, highly flexible laboratory systems. Bundled know-how, also from the fields of laser-beam source and optics development as well as process monitoring, enables it to offer its customers customized applications and innovations. In addition, Fraunhofer ILT develops novel materials for laser-based Additive Manufacturing. In addition to LPBF, the “Laser Powder Bed Fusion” competence area is also involved in process and system development for the laser-based production of functionally adapted polymer components using selective laser sintering (as part of a cooperative research group with Aachen University of Applied Sciences).

With Laser Material Deposition, and in particular with the multiple award-winning process of “Extreme High-speed Laser Material Deposition” (EHLA), metal tracks with layer thicknesses between 0.01 mm and 2 mm can be applied with high precision to almost any metallic base material in a very short time. By superimposing several weld beads, EHLA can generate two-dimensional coatings, for example for wear and corrosion protection, or functional coatings. If several layers are welded on top of each other, the process can also be used for repair and Additive Manufacturing. Due to the precisely controllable energy input, components and alloys can be processed that are generally considered difficult to weld. Fraunhofer ILT supports its industrial clients from generating ideas and consulting to developing adapted processes, system technology and process monitoring all the way to process transfer to the customer’s plants. The institute has a wide range of available plant technology, analysis capacity and extensive development know-how for diverse user industries – for example in the aerospace, automotive or energy sectors – that allows it to efficiently implement a wide variety of projects.
