| Abstract | Additive Manufacturing (AM) is a promising direct manufacturing technology and geometric accuracy of AM built products is crucial to fulfill the promise of AM. The prediction of the out-of-plane or z direction geometric errors has been a daunting task for AM. Although Finite Element Method simulation has been extensively applied to predict 3D deformation and distortion, improving part accuracy purely based on such simulation still needs significant methodology development. We have been establishing an alternative strategy that can be predictive and transparent to specific products and AM processes. Successful results have been accomplished in our previous work to predict the in-plane (x-y plane) geometric errors. In this study we aim to extend the methodology to the out-of-plane geometric error prediction. We provide a novel spatial deviation formulation in which both in-plane and out-of-plane errors are placed under a consistent mathematical framework. The derived predictive model for out-of-plane errors is validated through experimentation using a stereolithography process. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
