In this article, we propose to continue our investigation on the analysis of the powder bed laser melting process for the direct manufacturing. First, we describe the powder bed laser melting process. If the process is now industrially used, the fusion of the powder and its influence on the stability of the melt pool is not clearly understood. The objective of the study is to understand how the powder is fused and how a change in process...$28.00

Nowadays, laser machining of metals has some
advantages over more traditional processes. For
example, there is greater flexibility of use and no
mechanical contact with the surface. In micromachining,
shorter pulses re...$28.00
