Abstract: Solid freeform fabrication system has recently been used in many
practical areas for fast manufacturing of a concept model. Prototype model can
easily be made using a solid freeform fabrication system at the product
developing step for checking and correcting the probable design error. The
system considered for this paper basically consists of laser cutting apparatus
and material handling equipment. The basic principle of the process is such
that 3D CAD data is sliced into thin 2D layers, each slice is cut by laser
source along the profile of the 2D layer information and the slices are stacked
for sintering in a furnace. Material for the process initially was raw ceramic
green tape and becomes hard enough for practical use after sintering.
