The use of porous engineered materials is gaining popularity in biomedical implant manufacture due to its capability to promote increased osseointegration and cell proliferation. A method to produce such parts is laser direct metal deposition (LDMD) - a rapid manufacturing technique that has much flexibility. In this work, a 1.5 kW high power diod...$28.00

Direct Laser Deposition (DLD) method is relatively new technology which has significantly matured in last few years. Although this technique has been well know from the mid 80s, process control is still under investigation. The major application of DLD is in the repair or modification of existing parts or the manufacture of completely new 2-D or 3-D parts. This technology is also commonly used for the addition of special surface layer qualities on a base mate...$28.00

Numerous research centres all over the world are involved in the study of laser surface modification. By controlling laser parameters such as the amount of power, scanning speed, and pulse duration, it is possible to form coatings with different surface properties, including surface geometry, microhardness, stress states or resistance to wear. One of the cheapest and commo...$28.00

Presented at ICALEO 2008
A method is currently being developed to temporally characterize the energy absorption in laser beam spot welds. As a spot weld is created, absorption of laser energy changes with the condition of the weld (initial melting conduction keyhole). By relating the known pulse energy to the energy scattered during welding, a time resolved description of energy absorption can be determined. The method discussed uses a gold plated i...$28.00
