Title : Additive Manufacturing: Processes and Trends

Abstract

Additive Manufacturing (AM) technologies enable the fabrication of parts and devices that are geometrically complex and can have complex material compositions and functionalities. The field has changed tremendously in the past 10 years and is arguably changing even faster today. Hence, it is imperative to understand the trends that are likely to define the next 5-10 years of progress in the AM industry and research.To set the stage, a brief survey of AM processes, materials, and capabilities will be presented. Some of the trends to be highlighted include the fast pace of growth as measured by the size of the AM market. Up until recently, AM machine vendors and service bureaus were small companies ‐ not anymore with the likes of GE and HP getting into the market. The adoption of AM as a production technology, in contrast to prototyping, has accelerated in recent years, as has the growth of the consumer side of the business. An interesting trend is the adoption of technologies and hardware from the machine tool industry, which will accelerate the usage of AM as a production technology. Size ranges have expanded tremendously, from sub-micron dimensions to buildings.Technologies for multiple materials and real-time sensing and controls have emerged that can drastically impact the field. Finally, we are seeing major moves by software vendors to upgrade their products to include AM related considerations. Taken together, the future of AM promises to be even more exciting than the past decades.
