Purpose : This paper aims to provide a multi-objective optimization problem in design for manufacturing (DFM) approach for fused deposition modeling (FDM). This method considers the manufacturing criteria and constraints during the design by selecting the best manufacturing parameters to guide the designer and manufacturer in fabrication with FDM....
Conference Paper
The Selective Laser Melting (SLM) process induces tensile residual stresses that impact negatively on the mechanical characteristics of the material. In literature, the well-known solution to overcome this issue is a post-process heat treatment. However, this solution is usually accompanied by a loss of the mechanical properties. Therefore, the aim...

In Additive Manufacturing (AM), a main material and a support material can be required to manufacture a model. The support material sometimes remains inside the prototyped model and is difficult to clean. Removing the support material results in a waste of time, material and money, which goes against the principles of Ecodesign, especially when the...

In the rapid prototyping area, technologies used a construction material and a support material to manufacture geometry. The support material is sometimes conserved in the prototyped part and cleared on its outside. This elimination of support material involves a cost for the user. In some cases, the support hasn't structural rules and becomes a ma...

Le prototypage rapide permet la réalisation de pièces en très petites séries qui ne sont pas systématiquement « bonnes matières ». A l’opposé, l’injection plastique pallie ce défaut mais en augmentant considérablement les investissements, et de ce fait, implique une production en grande série. Cette étude vise à cibler un marché de personne chercha...
