| Abstract | Fused Deposition Modeling is a worldwide diffused Additive Manufacturing technology able to fabricate prototypes, tooling and end user parts directly from a virtual model. The layer by layer fabrication allows having no limitation of part shape complexity but some weaknesses exist about the obtainable accuracy. The dimensional deviations observed on a physical prototype are of the order of some tenths of millimeter depending upon the local slope of the surface. In order to enhance the accuracy, the idea is to compensate for the deviations by means of a virtual model offset. For the purpose a novel methodology has been developed to offset the triangular mesh: it operates an offset with a variable radius of the vertices without changing their interconnections. In this way the new virtual model is generated in a stable and robust way without modifying the Fused Deposition Modeling process chain. The experimentation carried out both on simple and complex geometries points out a marked improvement of the dimensional accuracy. The assessment has been performed by dimensional measurements and by a preliminary analysis of the errors introduced by the offset method. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
