Abstract

AbstractPowder bed laser 3D printing performed using polar coordinates, called Spiral Growth Manufacturing (SGM), allows manufacturing axisymmetric revolution parts in less time compared to conventional cartesian laser printing or Selective Laser Melting (SLM). In this work, a device to perform SGM operating under polar coordinates is presented. The study considered the manufacture of rings by 3D laser printing, both polar (SGM) and cartesian (SLM), from AISI 316L steel powder. These were compared dimensionally and with regards to density and build rate efficiency of the process. The rings have a nominal outer diameter of up to 75 mm and inner one of 45 mm. Results indicate that geometric dimensional precision, specific and nominal density of the polar rings are very close to those obtained through cartesian process. Build rate efficiency of rings by polar printing is on average 5% higher than for cartesian obtained rings.
