Metal AM alloy development, it is necessary to first examine the strategiesĪnd principles used currently to develop new AM alloys. In order to examine the role of materials science and engineering in Materials Science and Engineering in exercising material freedom in metal This paper is an attempt to examine the role of Therefore, the metal AM industry is struggling with new alloy development Most of the conventional metalĪlloys do not respond in the same fashion as in conventional manufacturingīecause of the rapid melting and solidification they undergo in AM processes. In conventional processes such as forging. Or mechanical properties offered by the same alloys when manufactured There are veryįew metal alloys that are additively manufacturable and have the quality Replacing the existing conventionally produced materials. Most of the AM metal parts are made from conventional alloys

Similar to the design freedom, metal AM also provides materialįreedom that has not been sufficiently explored, although major initiativesĪre in place. The limitations in the microstructural and structural deficiencies inherent in Majority of these partsĪre functional but non-critical or have large factor of safety because of Where advantages of AM can be taken immediately, when just in time manufacturing and lead time reduction are critical. Īpplication of metal AM has now spread in all industrial sectors, especially Prototype, custom parts, and parts made from expensive materials. Production of highly engineered parts with complex geometry, low volume, The ability of metal AM to customize for each patient rapidly at the point ofĬurrently, it is well established that the metal AM is most suitable for Medical prosthetics and implants, on the other hand, utilize Of metal components and drastically increase buy-to-fly ratio in aerospace Optimization, the design freedom that AM offers are utilized to reduce weight Because of its inherentĪdvantages to manufacture complex and customizable shapes directly fromĬAD files without hard tooling, Aerospace and Medical prosthetic industries Today Metal AM is a reality, not only for prototype fabrication,Īlso for functional parts in all industrial sectors. High energy sources such as electron beam, laser, plasma, and electricĪrc to rapidly melt and solidify metals in a thin layer made metal AM With advances in the ability to direct, control, and manage Physical structures, and to check fit and function for engineering productsĪnd systems. These early prototypes were madeįorm photo polymeric materials to bring design to perfection, replicate Stereolithographic technique to build shapes one layer at a time to KeywordsĪdditive Manufacturing or Direct Manufacturing, popularly knownĪs 3D Printing, has become the leading-edge manufacturing technology.Ĭurrent form of Additive Manufacturing (AM) began its journey utilizing The examples with new Aluminum AM alloys will be presented, leading to a path of developing advanced and higher performance products for critical applications. This presentation will demonstrate how fundamental MSE principles can be utilized to develop new materials, optimize metal AM and post processing, and their controls that cannot be achieved by conventional manufacturing methods.

This presentation will show the essence of metallurgical principles in realizing full scope of material freedom in metal additive manufacturing. This presentation will highlight the increasing role of Materials Science and Engineering in metal AM technologies. While new metal AM materials are being developed, the role of Materials Science and Engineering (MSE) is becoming more apparent than ever before. However, in order to realize further and widespread use of metal AM for manufacturing critical components, it is necessary to explore the inherent material freedom in AM. Design freedom that the AM processes offer has led to design and engineering of new, complex, light-weight structures in all applications. Today Metal Additive Manufacturing (MAM) is a reality, not only for prototype fabrication, also for functional parts in all industrial sectors. Additive Manufacturing or Direct Manufacturing, popularly known as 3D Printing, has become the leading-edge manufacturing technology.
