Multi‐Scale Characterization of PLA Composites With Natural‐Based Reinforcements: From Filament to 3D‐Printed Parts

Polymer Composites, EarlyView.
Thermal, microstructural, and mechanical characterization of 3D‐printed PLA composite parts. ABSTRACT To address plastic waste and agricultural residue underutilization, this study evaluates the thermal (DSC and FTIR), microstructural (SEM), and mechanical behavior of polylactic acid (PLA) reinforced with flax fibers and olive pit particles, processed ...

Vapor chemical composition in electron beam powder bed fusion using Ti–6Al–4V powder

The International Journal of Advanced Manufacturing Technology
This study investigates the vapor chemical composition, during the melting step of an electron beam powder bed fusion process using Ti–6Al–4V powder. A phenomenological model is proposed to analyze and discuss the vapor composition. The model focus on the heat dissipation of the molten powder.

Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

steel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

A thermo-mechanical model for hot cracking susceptibility in electron beam powder bed fusion of Ni-base superalloys

Materials & Design
Hot cracking is a major challenge in the additive manufacturing of Ni-base superalloys. Most cracking indicators only consider the alloy composition and its effects on solidification behavior, strength, and ductility.

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Recovery of residual powder : For Electron Beam Powder Bed Fusion

Additive manufacturing (AM) allows production of complex parts, which would be hard to produce with conventional methods. Theoretically the technology is also more efficient with minimal material losses. However, with the AMmethod of powder bed fusion electron beam (PBF-EB) it has not yet been fully established if powder can be reused.
