Additive manufacturing of micro-components (micro 3-D printing)
In the field of job order production, the Laser Zentrum Hannover e.V. (LZH) manufactures micro-components made of liquid, light-curable plastics or carries out feasibility studies.
Additive manufacturing of polymer parts
The LZH offers consulting, feasibility studies and process development for the additive manufacturing of polymer parts. With micro stereo lithography, 3D parts can be manufactured with a resolution of > 5 µm. An aerosol jet process enables multi-material manufacturing processes on uneven surfaces, too.
Cladding (deposition welding) of large areas
For the cladding of large areas, laser-assisted double-wire deposition welding has been developed.
Consulting for the manufacturing of 2D and 3D micro and nanostructures
Several technologies are available for the additive manufacturing of two- and three-dimensional micro and nanostructures. The Laser Zentrum Hannover e.V. (LZH) supports customers in identifying the best-suited technology and can manufacture the prototypes.
Development of processing systems and system components
The Machines and Controls Group designs, constructs and makes processing systems and system components, mainly for deposition welding and surface technology. This also includes the necessary process development. From the idea to realization to implementation of the process system, the LZH experts accompany their customers through the whole development process.
Laser alloying
Using laser alloying, wear-resistant coatings can be placed on different materials. For example, materials with a high carbon affinity can be embedded in the surface of a basis material. These embedded materials react with the carbon in the basis material, forming wear-resistant carbides.
In this way, the lifetime of tools can be prolonged.
Laser-assisted GMA cladding (deposition welding)
During laser-assisted arc deposition welding, the laser beam stabilizes and guides the electrical arc. Thus, low dilution rates (<5%) and a precise positioning of the deposition material can be achieved.
Laser cladding (laser deposition welding)
With the application of material by laser cladding, components can both be protected from wear or repaired.
Laser dispersion
Using laser dispersion, metal-ceramic coatings can, for example, be added to moulding tools. These coating improve both the wear and corrosion characteristics of the tools, and can thus increase tool life.
