BAM@Hannover Messe: innovative 3D printing method for space flight

24.04.2018

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then fusing it using selective laser sintering. Production is controlled by data models.

Metallic powder is locally melted by intensive laser radiation in each layer. What makes this method special is that the application of the powder layers takes place under zero gravity conditions. For this purpose, a process gas – in this case nitrogen – is drawn through the powder layers in order to stabilise the powder bed without gravity.

The procedure has already been successfully tested in two parabolic flight campaigns in cooperation with the Clausthal University of Technology, and the Institute for Composite Structures and Adaptive Systems of the German Aerospace Center (DLR) in Braunschweig.

Metallic powders pose a challenge because they are potentially flammable and explosive. But the research group has developed a method that enables processing of metallic powders in space under a protective gas atmosphere.

"We used a completely new technology to print a wrench for the first time under zero gravity in our latest parabolic flight campaign in March," explains Prof. Jens Günster, project manager and head of BAM’s Ceramic Processing and Biomaterials division. "We are pleased to be able to present our research results at the Hannover Messe and show our method’s potential to the space industry."

Some of the processes used have already been internationally patented. They are based on two patent families that were jointly registered by BAM and Clausthal University of Technology within Germany and by BAM alone outside Germany.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
