3D printing isn’t just confined to plastic. Learn all about direct metal laser sintering, one of few 3D printing technologies capable of making parts directly from metal. Removing a DMLS print from the powder. Source: Direct metal laser sintering (DMLS) is one of the few 3D printing technologies that directly create a metal part from its 3D computer model. This process is an advancement of powder metallurgy (PM) , a mature metal-molding technology that uses heat and pressure to form powdered metal parts. The working material for this 3D printing process is finely powdered metal. Typically the manufactured size of the metal particles is 20 – 40 micrometers. The particle size and shape limit the detail resolution of the final part. Smaller metal particle size and less variation allow better resolution. Other resolution limits in this technology are the layer height and the size of the laser spot. […]
