“…6, to visualize the quality of the prototype that the MMLM machine will subsequently deliver. A build-time estimation algorithm has been developed to estimate the fabrication time [26]. Besides, dimensional deviations of the prototype beyond a tolerance limit can be identified by superimposing the colour heart STL model on its digital prototype.…”

This paper describes a multi-material virtual prototyping (MMVP) system for modelling and digital fabrication of discrete and functionally graded multi-material objects for biomedical applications. The MMVP system consists of a DMMVP module, an FGMVP module, and a virtual reality (VR) simulation module. The DMMVP module is used for design and process planning of discrete multi-material (DMM) objects, while the FGMVP module is for functionally graded multimaterial (FGM) objects. The VR simulation module integrates these two modules to perform digital fabrication of multimaterial objects, which can be subsequently visualized and analyzed in a virtual environment to optimize MMLM processes for fabrication of product prototypes. Using the MMVP system, two biomedical objects, including a human dextrocardic heart made of discrete multi-materials and a hip joint assembly of FGM are modelled and digitally fabricated for visualization and analysis in a VR environment. These studies show the MMVP system is a practical tool for modelling, visualization, process planning, and subsequent fabrication of biomedical objects of discrete and functionally graded multi-materials for biomedical applications.

“…A suite of algorithms for LM process planning, such as slicing, choice of build-direction, model orientation and layer thickness, generation of sequential and concurrent multitoolpaths, and build-time estimation, are incorporated in the proposed VP system. The details of these algorithms have been presented in (Choi & Samavedam, 2001& 2003Choi & Chan, 2002;Choi & Kwok, 2002Choi & Cheung, 2005a, 2005b, 2006& 2007. This chapter focuses on the development of the VR system.…”

“…The proposed VP system consists mainly of a suite of software packages to facilitate and simulate various stages of an MMLM process, including colour STL modelling, slicing, topological hierarchy sorting of slice contours for subsequent process planning, multitoolpath planning and generation, and build-time estimation (Choi & Cheung, 2005a, 2005b, 2006& 2007. In particular, these packages are integrated with a set of control modules and VR graphics kernels that drive both desktop-and CAVE-based VR platforms to create semiand full-immersive visualisation of the MMLM process at the user's choice.…”
