New 3D printer tech uses elliptical laser beams

New 3D printer tech uses elliptical laser beams to stir molten metal and create ‘alloys-on-demand’ — existing machinery can implement technique in software meaning for more convenient, stronger alloy printing

NIST has demonstrated a metal 3D printing method that stirs molten metal during the print by sending the laser along looping elliptical paths instead of straight lines.
