Special Issue Information

Dear Colleagues,

Laser material processing is increasingly used in industry due to multiple advantages in supporting or replacing conventional processing technologies. Modern equipment and simulation methods help to increase our understanding of laser beam processes, which is highly desired to guarantee high-quality production and products.

The Special Issue of Applied Sciences on “Latest Advances in laser-based Manufacturing Technologies” welcomes all kinds of novel articles that help to explain the complex phenomena occurring during laser–material interaction and material behavior. Addressed topics are (but are not limited to):

  • Fundamentals of laser–material interaction;
  • Process design;
  • Spatial and temporal beam shaping;
  • Process monitoring and control;
  • Experimental observation of process dynamics and defect formation;
  • Material properties;
  • Process simulations;
  • Quality assurance.

The Special Issue shall be a platform to share recent research in laser processing. The journal will publish all types of papers: communications, articles, and reviews. The standards for submissions are of high quality, impact, and novelty. The papers must be interesting for a wide audience in all fields of science and technology.

Laser Powder-Bed Fusion (LPBF) is one method in Additive Manufacturing where layer-wise complex structures can be built. However, although the LPBF machines produce promising parts, the efficiency and process speed are typically still low, which can make the process expensive and uneconomical. Recent research showed that volume elements in the parts can be melted several times, while only a small material volume is added, which indicates a high loss of energy. In order to understand the process better, in this work, theoretical modeling and smart powder-bed experiments were designed to explain the impact on the track dimensions based on the previously built tracks and layers. It was found that the powder availability varies for each track and has an alternating character within and between layers. The comparison of the simulation and experimental results indicates that the powder pick-up from neighboring powder volumes is the main reason for the variations of the powder availability.
