Under the main topic "Creatively Additive", the Laser Zentrum Hannover e.V. (LZH) will show creative, light-based and convincing solutions for special requirements in the field of additive manufacturing and 3D printing at the Hannover Messe 2018. From April 23rd to 27th, 2018, the LZH can be found at the Pavilion of the State of Lower Saxony in hall 2 at stand A08.
The LZH develops and optimizes special processes for established materials as well as special materials. The scientists of the LZH conduct research on both polymers and metals.
At the Hannover Messe 2018, the LZH will present special ways of additive manufacturing, here the single-crystalline repair of high-quality capital goods.
Rarely do products consist of only one material. In order to be able to manufacture these additively in one go, the LZH is conducting research on multi-material printing. With nozzle-based methods, for example, the scientists can create hardness gradients in a polymer component. This is interesting, among other things, for wearables, in-ear hearing aids and headphones.
They should be soft and comfortable on the outside but hard enough on the inside to optimally ensure their function. Researchers continue to work on embedding metals in polymer matrices. Another option would be to print conductors or to magnetize components in that way. For this topic, the institute is looking for interested companies for joint research projects.
Lightweight, individual, robust: additive manufacturing of metal
The additive manufacturing of metals enables completely new ways of constructing components: Components for the automotive industry and the aerospace industry become lighter; special materials such as magnesium are used in lightweight construction as well as in biomedical engineering, functions can be integrated directly in one manufacturing step, implants are adapted exactly to the body.
Selective Laser (micro)Melting, which is being researched by the LZH scientists, makes all these applications possible. Additive manufacturing is just as suitable for repairing or protecting valuable components. With laser-assisted deposition welding, the LZH can apply large quantities of material to provide large components, such as shafts, with a protective layer. At present, 7.5 kilograms per hour can be reliably deposited. Valuable goods such as turbine blades can be repaired by single-crystalline laser deposition welding.
The LZH is not only pursuing creative approaches in additive manufacturing - on the exhibition stand, in addition to additive manufacturing, the institute will highlight the safe deactivation of World War II bombs, and other areas of laser material processing.

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current to run a device and ultimately fails.
Materials with a higher lithium ion storage capacity are either too heavy or the wrong shape to replace graphite, the electrode material currently used in...
To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the...
Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.
The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.
At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.
Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...
