The Role of Fibre Lasers in Selective Layer Melting Process
Authors:
John Tinson, SPI Lasers; Southampton Great Britain
Presented at ICALEO 2006
Rapid prototyping has evolved from polymer form and fit components to fully functional metallic form, fit and functional parts. Advances in build speeds and fill density as well as the creation of titanium, stainless, aluminum and cobolt chrome powders has taken laser based rapid prototyping fully into the realms of tool free rapid production. This paper presents new results, with the fiber laser enabling better surface finish and fill density. Equipment, materials and applications associated with this process are presented, and the laser attributes re...$28.00

Presented at ICALEO 2006
Small integrated circuit packages pose a challenge in marking them, due to their extremely small size and thin wall-thickness. A marker machine, using a special fiber laser, has been developed to meet this need. Characters as small as 0.2 mm x 0.2 mm, with a marking depth of a few microns, can be marked at a speed of over 600 characters per second. We also introduce a pulsed fiber laser marker that can selectively process submicron thin films deposited o...$28.00
