| description | Selective Laser Sintering (SLS) is a combined technology of computer and laser to
produce complex 3D prototypes directly from CAD modeling. One of the main advantages of
employing this technology is that the non-sintered powder can be recycled and reused for another
fabrication. However, the fabricated part could be affected by rough and unacceptable surface
texture. As a result, the parts may have to be scrapped and the build has to be repeated with a higher
ratio of new material. This paper presents an experimental study of the thermal properties of new
and recycled of PA12 powder in the Laser Sintering process. The influence of melting temperature,
glass transition temperature and crystallization temperature on these properties is investigated. The
experimental results have shown that PA12 powder with high melt flow rate, low melting
temperature, low glass transition temperature and low degree of crystallization temperature could
improve the sintering process. |
