New etching technique improves powder absorption for metal 3D printing
A team from Lawrence Livermore National Laboratory, Stanford University, and the University of Pennsylvania has introduced a new wet chemical etching process to modify the surface of traditional metal powders used in 3D printing. By creating nanoscale grooves and textures, the researchers reportedly increased the absorption rate of these powders by up to 70%, allowing for more effective energy transfer…
