Nowadays, the use of 3D printing is becoming a key process for on-demand and customized manufacturing. One most flexible techniques fused deposition modeling (FDM), where combination multiple materials was recently introduced. A quantum leap in part design possible by integrating local variations between that allow expanded functionality to be built into single part. Therefore, co-extrusion mat...

Abstract In this paper, the shock response of functionally graded Al-PTFE granular composites is firstly investigated by means mesoscale simulations. A tailored arrangement filler infiltrated with matrix to study effects density gradient on mechanical and chemical characteristics material under impact loading. Based wave propagations, noticeable differences among pressure, temperature, strain a...

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 to model discrete multi-material (DMM) objects, while the FGMVP modu...
