Laser Zentrum Hannover e.V. (LZH) is presenting how production cycles using laser technology can save resources, under the motto of “Sustainability is our Focus”. This year, the LZH will be exhibiting – for the first time – at the Lower Saxony Pavilion in hall 2, stand A08.
The LZH is presenting at this year’s Hannover Messe (7-11 avril 2014, Hanovre, Allemagne), under the theme of “Sustainability is our Focus – Laser-based Production Cycles”, how laser technology can save energy and/or material during production, processing and repair and recycling.
Manufacturing: Production “out of the blue”
Laser Additive Manufacturing (LAM) can be used to produce individual workpieces in only one step. The left over material can usually be used for new production cycles. Using special materials is in particular interesting for the biomedical field. Bioresorbable magnesium implants and micro-actuators made of shape memory alloys can be used for new healing approaches. Polymer-workpieces with high resolutions make prototypes and small series production of tools and special machines possible. Fair visitors can see how an LAM unit functions, which materials can be used, and what the finished workpieces can be used for.
Processing: Saving Time, Processing Steps and Raw Materials
Hybrid welding can be used for more precise and faster processing of metal workpieces. From pipeline building to coating of tools, laser based processes save work steps and materials. Even fiber composites can be precisely processed using lasers. The LZH is currently doing research on automated cutting of these lightweight materials, so that they can soon be used for mass production for automobile and aviation construction in the future.
Repair and Recycling: Extending
the Lifetime of Lightweight Materials
Damage to wind power systems and aircraft wings can be selectively ablated and repaired using the laser, so that a whole rotor or wing need not be replaced. At the LZH stand, visitors can see how laser technology can be used to shorten the repair time and save material for leading-edge slats of a CFRP airplane wing. Visitors can also learn how CFRP cuttings can be recycled for use in new materials.
