碩士 === 逢甲大學 === 材料與製造工程所 === 95 === Rapid Prototyping technology is base on layered manufacturing, If the surface in a curvature bigger by layer upon layer in the process, between the layer and layer has an kind of erroneous phenomenon, this phenomenon is called stair stepping effect, in order to reduce the stair stepping effect brought erroneous phenomenon, the study discuss of how to make use of adaptive slicing to promote the prototype the quality and precision, by the experimental manufacture model result is SLC adaptive slicing method surpasses STL slicing method in quality and precision. The study discuss another an purpose is make use of Taguchi experiment methods to dispose experimental parameter, hope find most suitable operational parameter in rapid prototype machine, discussion focal point in influence prototype quality controlling factors, and collocation with orthogonal array calculate, analyzes each group of Parameter to the prototype quality characteristic, The experiment analyzes result is set parameter on A1B1C3D3 , factor A choose level 1 is slicing thickness is 0.075 (mm), factor B choose level 1 is laser penetration depth is 4.7 (mils), factor C choose level 3 is laser critical exposure energy is 8.85 mj/cm2 , factor D choose level 3 is work space set on right, by confirmation parameter obtained result is prototype has the obvious promotion in the precision.
