The future of 3D printing will be the focus at formnext 2018 in Frankfurt am Main. For this, the Fraunhofer Focus Project futureAM offers particularly exciting insights, a project in which six Fraunhofer institutes are involved. The partners are doing both, comprehensively looking at digital and physical added value right from the order to the finished component; and at the leap into a new technology generation of additive manufacturing.

Thin organic layers provide machines and equipment with new functions. They enable, for example, tiny energy recuperators. In future, these will be installed on pipes or other surfaces in order to convert waste heat into electricity. The experts at the Fraunhofer Institute for Material and Beam Technology IWS Dresden use ink based on conductive polymers for this purpose.

Additive manufacturing processes are booming, with the rapid growth of the formnext trade fair a clear indication of this. At formnext 2018, in cooperation with the Chair for Technology of Optical Systems TOS at RWTH Aachen University, the Fraunhofer Institute for Laser Technology ILT will be showing a new process in which the component in the powder bed is heated with laser diodes. As a result, distortion can be reduced, taller parts generated and new materials used.

Filigree engravings on external surfaces of aircraft are intended to ensure that airflow remains smooth and drag on the aircraft low. For this, engineers at the Fraunhofer Institute for Material and Beam Technology IWS, the Technische Universität Dresden and Airbus have developed a laser process that produces textured surfaces at high throughput making surface contamination more difficult.

Surface Finishing at High Speed

7.8.2018

High precision and high quality, but too slow – this is how most laser processes for surface finishing can be described. In the EU research project ultraSURFACE, the Fraunhofer Institute for Laser Technology ILT in Aachen, together with nine international partners, is developing two new optics by the end of 2018. With them, the laser beam shape can be specifically and quickly adapted to constantly changing processing situations. In the near future, lasers will be able to polish, coat or structure surfaces up to ten times faster than before thanks to this tuning.

3D-Printing: Support structures to prevent vibrations in post-processing operations for thin-walled parts

16.7.2018

© Fraunhofer IPT

One of the main features of additive manufacturing processes such as 3D-printing is that the complexity of the component shapes it produces, is virtually unlimited. However, high surface quality in metallic components can frequently be achieved only via milling or grinding finishing operations. Milling operations conducted on thin-walled parts in particular often cause vibrations which impact negatively on part accuracy and on machining time.

Global competition in the chemical industry, with increasingly dynamic markets and product cycles, requires shorter process development times and flexible and efficient production processes. By combining micro chemical engineering and spectroscopic process analysis in different spectral ranges, the time-to-market can be shortened, and an extremely fast and systematic screening of a variety of process conditions can be achieved.

Bonding without adhesive

20.2.2018

© Fraunhofer IWS

The Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS Dresden has developed a new process for joining materials with different properties. Thermal direct joining presses laser-structured metal with thermoplastic components and heats them locally. This causes the thermoplastic to melt, to penetrate into the structures and to adhere to the surface. A specially developed joining gun generates robust connections within seconds. The "HeatPressCool-Integrative" (HPCI) process is highly suitable for replacing complex adhesive processes.
