The two wavelength imaging setup developed resolves temperature and accounts for unknown emissivity values during the material transition from powder to liquid to a bulk solid. The first measurements of fully resolved surface temperature fields are presented for a simple component with an overhanging ...
A powder and/or polyhedral grains are produced by directing one or more jets 16 of liquid at a body of the solid material 1, thereby causing the ablation of powder particles from the solid material 1. The jet or jets 16 of liquid may be controlled to cut polyhedral grains from the ...
using one or several surfactants and/or co-surfactants, solid at normal temperatures as solid or solid mixture, whereby the liquid fragrance or fragrance mixture is dissolved in the above at a temperature above the solidification temperature of the solid or solid mixture and the solution subsequently...

(Supplementary Fig.7a, b), demonstrating that the observed LaB6nanoparticles are not the initial additives, but the product of re-precipitation from the liquid Cu during solidification after dissolving during laser melting. In addition, we also examined the top surface of the L-PBF fabricated 1.0...
