What metal additive manufacturing technologies exist?<\/h2>\n\n\n\n
\n
\n

There are three main technologies for producing metal parts using additive manufacturing:<\/h3>\n\n\n\n
  • Selective Laser Melting<\/strong> (SLM or Selective Laser Fusion). This technology is also sometimes called Powder Bed Fusion (PBF) or Direct Metal Laser Sintering (DMLS).<\/li>
  • Metal Binder Jetting<\/strong> (MBJ) o Inyecci\u00f3n de Aglutinante (sobre polvo de metal).<\/li>
  • Bound Metal Deposition<\/strong> or Bound Metal Deposotion<\/li><\/ul>\n<\/div>\n<\/div>\n\n\n\n

    Selective Laser Melting or SLM (\/PBF\/DMLS)<\/h2>\n\n\n\n

    Introduction<\/h4>\n\n\n\n

    SLM technology is one of several names for this technology. It was developed in 1995 at the Fraunhofer Institute ILT in Aachen, Germany. After patenting this technology, at the beginning of the 21st century, Doctor Dieter Schwarze started a business project that today is known as SLM Solutions. Doctor Schwarze continues, to this day, working at SLM Solutions and leading the most important advances in SLM technology (reactive materials, multi-laser, closed-loop dust management, etc.).<\/p>\n\n\n\n

    How it works?<\/h4>\n\n\n\n
    \n
    \n

    This technology is based on spreading a thin layer of metal powder on a metal plate. Using a high-power laser, we apply energy to said metal powder, fusing its particles together. In this simple way, we can produce the first \"slice\" of our metal part. Next, we extend another equal layer on top of the previous one and apply the laser on its surface again. On this occasion, the dust particles are going to merge with each other and with those immediately below, previously merged.<\/p>\n\n\n\n

    We repeat this process, layer by layer, until our part is, made up of fused powder particles, inside the printing vat, surrounded by loose powder.<\/p>\n\n\n\n

    Then we just have to extract the loose powder and sift it to use it again in the next impression, clean our piece and remove the supports that join it to the build plate.<\/p>\n<\/div>\n\n\n\n
