【 摘 要 】

Thirty years into its development, additive manufacturing has become a mainstream manufacturing process. Additive manufacturing build up parts by adding materials one layer at a time based on a computerized 3D solid model. It does not require the use of fixtures, cutting tools, coolants, and other auxiliary resources. Additive manufacturing (AM), also known as rapid prototyping (RP), is a powerful tool that offers the necessary competitiveness to worldwide companies. AM comprises the use of layer-by-layer manufacturing in order to build a part by addition of material. During this study a test piece was designed in order to compare the conventional, milling manufacturing process with additive manufacturing from the viewpoint of geometrical accuracy and the quality of surface roughness. The aim is to develop a test piece design and produce this work piece by milling technology and polyjet additive manufacturing method. The dimensional measurements of these workpieces will show the accuracy of the different technologies.
