By Frank Brueckner, Mirko Riede, Thomas Finaske, André Seidel, Steffen Nowotny, Christoph Leyens, Eckhard Beyer Laser Metal Deposition (LMD) is used for repair/redesign as well as for manufacturing of new parts. Thereby, wire or powder filler material is reabsorbed in the laser-induced melt pool resulting in a strong metallurgical bond with the subjacent substrate in combination […]

AM Building Value: 3D Printing Forecasts Bode Well for Lasers
By Geoff Giordano While news appears almost daily to highlight the latest novel item that might be capable of being produced with 3D printing, getting a handle on the value of opportunities in industrial additive manufacturing markets can be difficult. But a compelling picture is forming thanks to recent data. By 2025, 3D printing could […]
Hybrid Femtosecond Laser 3D Microfabrication: Reliable Tool for Fabrication of Functional Biochips
By Koji Sugioka The rapid development of the femtosecond laser has revolutionized materials processing due to its unique characteristics of ultrashort pulse width and extremely high peak intensity. In particular, the high peak intensity allows nonlinear interactions such as multiphoton absorption and tunneling ionization to be induced in transparent materials, which provides versatility in terms […]
Digital Photonic Production – The Future of Laser Applications
By Reinhart Poprawe One of the main challenges of modern manufacturing is the dilemma between scale and scope, i.e., the ability to produce high volumes at low prices, yet systematically integrating the increasing demand for individuality in the products. As a consequence, concepts for one piece flow at the cost of mass production are developed. […]
Rethinking Manufacturing: Additive Manufacturing as the New Design Paradigm
By Frederick Claus Additive manufacturing (or 3D printing) with metal has significantly advanced the fields of aerospace, medical and industrial manufacturing with complex geometries and expedited production by eliminating the cost and long lead times for traditional molds and tooling. Inherent limitations of metal working processes – such as investment casting, machining or die casting […]
