Abstract:
The supply chain is changing speedily and on a continuous basis to keep up with the rapid changes in the market, which are summarized as increased competition, changes in traditional customer bases, and changes in customers’ expectations. Thus, companies have to change their way of manufacturing final products in order to customize and expedite the delivery of products to customers. Additive manufacturing, the new production system, effectively and efficiently increases the capability of personalization during the manufacturing process. This consequently increases customer’s satisfaction and c

Abstract:
Additive manufacturing (AM), also known as 3D-printing is an automated manufacturing process in which the component is built layer upon layer from a predefined 3D computer model. In contrast to conventional manufacturing processes where a vast volume of material is wasted due to machining, AM only uses the material that the component consists of. In addition to material savings, the method has a number of potential benefits. Two of these are (1) a large design freedom which enables the production of complex geometries and (2) a reduced compexity in supply chain as parts can be printed on-deman

Abstract:
Additive manufacturing processes of many alloys are known to develop texture during the deposition process due to the rapid reheating and the directionality of the dissipation of heat. Titanium alloys and with respect to this study beta titanium alloys are especially susceptible to these effects. This work examines Ti-20wt%V and Ti-12wt%Mo deposited under normal additive manufacturing process parameters to examine the texture of these beta-stabilized alloys. Both microstructures contained columnar prior beta grains 1-2 mm in length beginning at the substrate with no visible equiaxed grains.

Abstract:
The overall aim of this study is to explore the nature of Industrial Additive Manufacturing Systems as implemented by commercial practitioners, with a specific focus on flexibility within the system and wider supply chain. This study is conducted from an Operations Management perspective to identify management implications arising from the application of contemporary Industrial Additive Manufacturing in the fulfilment of demand. The generation of the theoretical constructs and their evaluation is achieved through an abductive approach. The concept of an Industrial Additive Manufacturing System

Abstract:
Selective laser sintering (SLS) and fused filament fabrication (FFF) are significant methods in additive manufacturing (AM). As AM is increasingly being used to manufacture functional parts, there is a need to have quality systems for AM process, to ensure repeatability of properties or quality of part made by the process. The primary aim of this research is to develop quality systems for SLS and FFF processes of AM. In order to develop a quality system for SLS process based on defining a minimum set of tests to qualify a build, two SLS materials of Nylon 11 and Nylon 12 were investigated. Mel

Abstract:
Computer-controlled additive manufacturing (AM) processes, also known as three-dimensional (3D) printing, create 3D objects by the successive adding of a material or materials. While there have been tremendous developments in AM, the 3D printing of optics is lagging due to the limits in materials and tight requirements for optical applicaitons. We propose a new precision additive freeform optics manufacturing (AFOM) method using an pulsed infrared (IR) laser. Compared to ultraviolet (UV) curable materials, thermally curable optical silicones have a number of advantages, such as strong UV stabi

Abstract:
Additive manufacturing (AM) is an immature manufacturing technology which is often considered to have the potential of disrupting the manufacturing industry and many industrial companies are currently investigating how they can position themselves within the AM market. Technological innovations alone are often insufficient to fully exploit the benefits of new technology and requires to be accompanied with business model innovation. Consequently, companies face challenges to find guidance related to the application of AM; what to offer and to whom (value proposition), how to deliver such offeri

Abstract:
Additive Manufacturing (AM), also known as 3D-printing, is the process of joining materials layer by layerfrom a 3D-model data and has several advantages over traditional manufacturing techniques. AM is destinedto change the way products are designed and manufactured in the future. In recent years, the process hasrapidly gained interest in all industry segments due to its ability to create customized and complex geometriesfor no added costs. This study focuses on a rather unexplored area of application of AM, namely of a vehiclecomponent that traditionally is manufactured with conventional man
