Abstract
This work presents an investigation into the
Selective Laser Melting (SLM) of 24 carat gold
(Au) powder with a mean particle size of 24μm.
An SLM 100 system was used which is intended
for production of highly detailed and intricate
parts. Gold powder was tested for its properties
such as tap density, Particle Size distribution
(PSD) and reflectance etc. A suitable processing
window was identified and gold cubes were
produced using these parameters. Gold cubes
were also checked for their internal porosity and
mechanical properties.
