How to improve operations when 3D printing is used for manufacturing of parts for end use
Siavash Haghighat Khajavi, M.Sc.(Tech.), will defend the dissertation "Improving additive manufacturing enabled operations – A forward looking empirical study" on 6 April 2018 at 12 noon at the Aalto University School of Science.
Three-dimensional (3D) printing is a production technology previously used for prototyping. Recent improvements allow for new applications, such as on-demand production of final parts. This is exciting from an operations management perspective as allows for manufacturing customized parts in very low quantities anywhere in the world, without the costs of mold making or tool making. 3D printing also makes it possible to combine many parts into one part and simplify the assembly and logistics.
The starting point of this research was not to compare 3D printing to conventional manufacturing, but instead to explore ways of using 3D printing to improve operations and supply chain management. The novel uses explored in the thesis are; production near the point of use, dynamic change over from 3D printing to conventional manufacturing as demand increases in a new product launch, and the use of 3D printing for directly producing parts for assembly as kits. The findings are based on the results of five articles. Real-world cases and experiments were used in this research.
As the 3D printing improvement continues, it is important to show the managers of manufacturing companies, what are the requirements and also the benefits of implementing 3D printing for production.
