    A compositionally graded material has been fabricated using Direct Laser Fabrication technology. A burning resistant alloy Ti-25V-15Cr-2Al-0.2C powder and a Ti-6Al-4V wire are used in this study. Two types of feedstock were fed simultaneously into the laser focal point with the mixing ratio varying from the bottom to top of the samples to achieve compo...

    Direct laser deposition is an advanced manufacturing technique. Combined with CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) it can be used to perform rapid tooling and prototyping applications in an industrial environment. Most existing laser cladding processes are adapted into slicing technology, in which a CAD mo...

    Recent Developments in Metal Laminated Tooling

    Thomas Himmer, Fraunhofer USA - CCL; Plymouth MI USA
    Presented at ICALEO 2005

    Based on recent achievements in the field of Metal Laminated Tooling or MELATO� it can be con-firmed that this unique technology contributes to enormous time and costs savings. There are special approaches for different manufac-turing technologies. For metal sheet forming tools, main objective is to reduce the costs for tool mak-ing. Unlike to this, laminated injection molding or pressure die casting tools are designed to reduce time and costs for the actual manufacturing process. This is achieved by integration of conformal cool-ing systems. Besides the reduce...

    Rapid Prototyping (RP) technology using Selective Laser Sintering (SLS) has been applied in many industrial areas such as modeling shape verification, machinery, materials and automobiles. It is supposed to be able to build in a short time any shape by layer-by-layer sintering of polymer, ceramic or metal powder. In order to develop more elaborate and speedy system for large objects t...

    In this article, we present new results on laser sintering of metallic or ceramic parts. First, we present the sintering process. The global process is overviewed, from the CAD file to the generation of the laser scanning of the powder.
    The principle of the machine is then described. We present the PM250 Phenix Systems machine and show the PM100 too.
    The sintering process has a large number of parameters (s...

    We demonstrate a flexible Yb-doped fiber laser that can generate up to 0.5mJ output energy or 11W average output power. The 1064nm single mode beam of a diode laser is amplified by a three stage amplifier. The first two amplification stages consist of single-mode fibers. The third stage uses LMA fiber. The output be...

    Presented at ICALEO 2005

    Only 10 years ago, the only commercially available high-power, fibre-delivered laser was the lamp-pumped Nd:YAG rod laser. Today however, diode-pumped Nd:YAG rod lasers, thin-disc Yb:YAG and Yb-fibre lasers are also available for material processing. This means that today's laser user needs to consider parameters such as beam quality and power density (and possibly others), in addition to the actual technology used in generating the laser beam, when se...

    Presented at ICALEO 2005

    Latest developments in laser physics have made available high-power fibre lasers with beam powers up to 17 kW and single mode fibre lasers with several 100 W at excellent beam quality. Adding to these properties their high energetic efficiency, their considerable estimated lifetime and their compact size, they might well be considered to be a viable alternative to both conventional lamp- or diode-pumped Nd:YAG- as well as to CO2-Lasers. Howeve...
