An innovative method to build support structures with a pulsed laser in the selective laser melting process

Rémy Glardon, Jamasp Jhabvala, Eric Boillat, Cédric André

In selective laser melting machines, continuous laser are usually used to melt the powder. The support structures, which are inevitable when dealing with elaborated pieces, necessitate a complex design by CAD in order to be easily removed. This paper propo ...

Study of the consolidation process under macro- and microscopic thermal effects in selective laser sintering and selective laser melting

Jamasp Jhabvala

Selective Laser Sintering (SLS) and Selective Laser Melting (SLM) are parent Additive Manufacturing processes using a laser to solidify metallic, ceramic, polymer or composite powders. During the process, the object is built layer by layer. A laser source ...

Real-time registration of airborne laser data with sub-decimeter accuracy

Jan Skaloud, Phillip Tomé, Yannick Stebler

This paper presents a methodology for the precise registering of airborne laser data directly in flight with an accuracy that is sufficient for the majority of derived products, such as digital terrain models. We first present the strategy that integrates ...

In-flight quality assessment and data processing for airborne laser scanning

Philipp Schär

One of the main problems of today's Airborne Laser Scanning (ALS) systems is the lack of reliable data QA/QC (Quality Assurance/ Quality Control) within or shortly after the airborne survey campaign. This thesis presents the development of methods to perfo ...

Laser applications in thin-film photovoltaics

Christophe Ballif, Andrea Feltrin, Benjamin Strahm

We review laser applications in thin-film photovoltaics (thin-film Si, CdTe, and Cu(In,Ga)Se2 solar cells). Lasers are applied in this growing field to manufacture modules, to monitor Si deposition processes, and to characterize opto-electrical properties ...
