Fabrication of Biomedical Prototypes with Locally Controlled Properties Using FDM

摘要: Abstract Biomedical structures have complex geometries and mechanical behaviors, are difficult to manufacture using traditional machining processes. This paper reports a study of fabrication biomedical fused deposition modelling (FDM) The theoretical experimental analyses behaviours FDM prototypes were carried out establish the constitutive models. A new set equations is proposed calculate elastic constants as functions constituent properties geometric characteristics, taking into account imperfect bonding among filaments void geometries. manufacturing parameters orientation density modeled for with functionally graded properties.
