Available in PDF, EPUB and Kindle. Book excerpt: The integration of additive manufacturing into traditional metal casting provides a wide range of rapid casting solutions. One important motive for rapid casting is additive manufacturings ability to create highly complex objects without any fixture or tooling requirements. Such advantages provide great design freedom for the geometry of cast metal parts. The objective in this thesis is to explore the part design opportunistic and restrictions of two rapid casting processes: (1) sand casting with 3D Sand Printing-fabricated molds and (2) investment casting using material extrusionfabricated wax-like patterns. Knowledge-based design guidelines are developed for both of these rapid casting processes through novel integration of topology optimization with design for casting and design for AM principles. For each process, a case study is conducted in which a mechanical metal benchmark is topologically optimized and redesigned following the proposed design rules. The redesigned parts are successfully cast and demonstrate improvements in mechanical performance and weight reduction.

Download or read book Rapid Prototyping written by Patri K. Venuvinod and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the dawn of civilization, mankind has been engaged in the conception and manufacture of discrete products to serve the functional needs of local customers and the tools (technology) needed by other craftsmen. In fact, much of the progress in civilization can be attributed to progress in discrete product manufacture. The functionality of a discrete object depends on two entities: form, and material composition. For instance, the aesthetic appearance of a sculpture depends upon its form whereas its durability depends upon the material composition. An ideal manufacturing process is one that is able to automatically generate any form (freeform) in any material. However, unfortunately, most traditional manufacturing processes are severely constrained on all these counts. There are three basic ways of creating form: conservative, subtractive, and additive. In the first approach, we take a material and apply the needed forces to deform it to the required shape, without either adding or removing material, i. e. , we conserve material. Many industrial processes such as forging, casting, sheet metal forming and extrusion emulate this approach. A problem with many of these approaches is that they focus on form generation without explicitly providing any means for controlling material composition. In fact, even form is not created directly. They merely duplicate the external form embedded in external tooling such as dies and molds and the internal form embedded in cores, etc. Till recently, we have had to resort to the 'subtractive' approach to create the form of the tooling.
