Selective Metal Sintering is cool but slow. Fear not, a technology that was initially developed to smooth and pattern laser beams is here to save the day, according to a new paper by Lawrence Livermore researchers.
In a paper titled “Diode-based additive manufacturing of metals using an optically-addressable light valve,” the researchers lay out a procedure for using an array of high-powered laser diodes among other things to print a whole layer of metal from powdered metal at one time. No more forward and backward, left and right. Just one bright flash and you’re done. Naturally, the technology is still …read more http://pje.fyi/PGnpHm
