3 A supporting structure for a workpiece printed by Selective Laser Sintering typed 3D printer

摘要

The present invention relates to a support structure of a laser sintering-type three dimensional printing sculpture, which supports a sculpture on a platform while being sintered together with a three-dimensional sculpture in a sintering process, and is removed from the sculpture by post-processing after the sintering process. The support structure is formed on a lower portion of the sculpture and a contact area with the platform is formed to be wider than a contact area with the sculpture, thereby being able to reduce material cost by reducing the consumption amount of the powder, and reduce the post-processing cost.
