Large‐Scale Interlaboratory Study Along the Entire Process Chain of Laser Powder Bed Fusion: Bridging Variability, Standards, and Optimization across Metals and Polymers

Advanced Engineering Materials, EarlyView.
What happens when 32 labs join forces to study nanoparticle‐modified powders? A data‐driven journey through laser powder bed fusion—now openly accessible for the entire additive manufacturing community—is studied. Laser powder bed fusion is a cornerstone technology for additive manufacturing (AM) of metals and polymers, yet challenges in achieving ...

Femtosecond Single‐ and Double‐Pulse Fabrication of Periodic Nanostructures on Stainless Steel for Surface‐Enhanced Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...

A Review on Electromagnetic Forming Process

Procedia Materials Science, 2014
AbstractElectromagnetic forming (EMF) is a non-contact forming technique. It is an impulse or high-velocity forming method using pulsed magnetic field by application of Lorentz’ forces to the work piece preferably made of highly electrically conductive material without having working medium and mechanical contact.
