This review emphasises on design constrains related to additive manufacturing and differences that may appear between virtual and real design. Metal additive manufacturing (AM) offers enormous potential for the rapid production of net-shaped, geometrically complex, lightweight, minimum-waste and customized metallic parts without the need for the expensive tools required in conventional casting, subtractive or formative manufacturing processes.1,2,3, – 4 Typically, metal AM provides high degrees of freedom in all aspects of component design, … Motaman, S. Amir H.; Kies, Fabian; Köhnen, Patrick; JOM, Vol. This article presents a literature survey on the impact that AM can have on design. /Resources 75 0 R Secondly, create a perfect design. endobj /Rotate 0 /MediaBox [0 0 594.95996 840.95996] 19 0 R] /Type /Page << << Additive Manufacturing processes have a digital dataflow that generates the instructions for the AM machine followed by a physical workflow that transforms the raw materials into final parts ().The process usually begins with a product idea, a 2D image such as a photograph, a set of 2D images like those derived from Computed Tomography (CT) scans, or a physical 3D object like a prototype or … /Type /Page Cathey and COO Rob Smith formed Optisys in West Jordan, Utah, with colleagues who share a combined 60 years’ experience that includes radio frequency (RF) design, satellite communications (SATCOM), mechanical engineering, and additive manufacturing (AM).
