Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

This study presents the development and optimization of a novel hybrid wire–powder Plasma Arc Directed Energy Deposition (DED) process for the fabrication of metal matrix composites (MMCs). The system integrates an auxiliary powder feeder into a conventional wire-based plasma DED setup, enabling the simultaneous deposition of a mild steel wire matrix and TiC ceramic powder reinforcement.

1. Application of Blue Laser in Additive Manufacturing and Laser Processing of Reflective Metals

Dr Hossein Ghasemi (Switzerland Innovation Park Biel/Bienne)

10/11/2026, 16:10

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

Processing of highly reflective metals such as copper and gold remains a significant challenge in laser-based additive manufacturing due to low absorption at infrared wavelengths, leading to process instabilities, excessive spatter, and defect formation. Recent advances in high-power blue laser sources offer a promising alternative, as these materials exhibit substantially higher absorption in...

32. Embedding Fiber-Optic Sensors in Metallic Components via LPBF for In-Situ Fuel Cell Diagnostics

Markus Reiter (AVL List GmbH)

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

Fuel cells (FCs) represent a key technology for sustainable hydrogen-based energy systems, with proton exchange membrane fuel cells (PEMFCs) offering high efficiency and suitability for mobility and stationary applications. However, their performance and durability are strongly influenced by local inhomogeneities such as uneven humidification, temperature gradients, and transient flooding...

9. Phase Transformation Kinetics and Lattice Parameter Evolution in LPBF Ti-6Al-4V: An In-Situ Synchrotron Study

F Friso (Institute of Materials and Process Engineering, Zurich University of Applied Sciences, Winterthur, Switzerland)

10/11/2026, 16:50

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

Laser Powder Bed Fusion (LPBF) of Ti-6Al-4V produces a characteristic non-equilibrium microstructure dominated by acicular α′ martensite due to high cooling rates inherent to the process. Recent studies have demonstrated the effect of build orientation on the thermal expansion of the as-printed Ti-6Al-4V. The observed expansion was partitioned into an isotropic reversible thermal strain and an...

53. Hybrid L-PBF Scanning Strategies for Additively Manufactured Ultra Thin-Walled Ti-6Al-4V TPMS Implants

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

Triply Periodic Minimal Surface (TPMS) structures have the potential to effectively tune the mechanical stiffness of orthopedic implants to mitigate stress shielding. To achieve the requisite low modulus, lattice wall thicknesses must approach the physical limits of Laser Powder Bed Fusion (L-PBF). While existing literature predominantly evaluates process parameters for walls thicker than 0.3...
