Abstract

In order to solve the problems of difficult storage and slow transmission of large data in remote transmission of 3D model for additive manufacturing, a lightweight method on MBD model is proposed. A lossless compression algorithm is applied and improved in this paper to simplified the product data model and minimize data exchange file. At the same time, a detailed geometric information model is retained to realize the rapid transmission of lightweight model, which provides a convenient method for remote transmission and acquisition of 3D model in additive manufacturing process. A case study on the MBD model of a packaging machine has verified is taken as an example to verify the feasibility of the method.
