Record attendance and spirited discussion from beginning to end marked the most successful Laser Additive Manufacturing (LAM®) Workshop to date. LIA’s sixth annual LAM spotlighted a multitude of promising developments in AM research, materials and processes, and previewed progress on the horizon.
Organized into two educational tracks, showcasing powder-bed processes March 12 and powder-fed technology March 13, LAM 2014 brimmed with case studies and highlights from around the world. More than 200 attendees traveled to Houston from more than a dozen countries, drawn not only by a wide-ranging slate of presentations but also the opportunity to talk directly with suppliers of AM solutions.

Carbonaceous deposits covering the surfaces of combustion engine components are known to cause abrasive wear, leading to increased oil consumption and reduce engine durability as well as performance. Remanufacturing is the process acting on end-of-life products to recover manufacturing standards and specifications. Dr. Yingchun Guan from Singapore Institute of Manufacturing Technology (SIMTech), Agency for Science, Technology and Research (A*STAR), and her co-workers have shown how laser technique may be used to remove stubborn carbonaceous deposits without degradation to substrate component.
Laser processing under normal atmospheric conditions may be considered as an environmentally friendly process where no chemicals were used. It has been demonstrated that micron to sub-micron sized surface particulates, corrosion spots as well as thin contamination layer may be cleanly removed without severe damage to the parent substrate. Typical applications include coating or paint removal, biomedical implants decontamination, artwork and cultural heritage conservation and restoration. [click to continue…]
