Laser consolidation (LC) is a novel manufacturing process that produces net-shape functional and metallurgically sound components by adding material based on a CAD model. Parts are built layer-by-layer using a laser beam to melt injected powder and re-solidifying it onto a substrate. As an alternative to conventional machining processes, the LC process builds complete net-shape functional parts or...$28.00

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...$28.00

Recent Developments in Metal Laminated Tooling
Authors:
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...$28.00

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...$28.00
