Mechanical characterization of parts fabricated using fused deposition modeling

TLDR

Layered manufacturing, an evolution of rapid prototyping, is shifting from prototype production to final product fabrication, demanding broader material choices, better surface quality, dimensional stability, and sufficient mechanical properties. The study aims to adapt fused deposition modeling for the fabrication of ceramic and multifunctional components. The authors present a methodology for mechanically characterizing products fabricated using fused deposition modeling.

Abstract

Layered manufacturing is an evolution of rapid prototyping (RP) techniques where the part is built in layers. While most of the previous applications focused on building “prototypes”, recent developments in this field enabled some of the prototyping methods to achieve an agile fabrication technology to produce the final product directly. A shift from prototyping to manufacturing of the final product necessitates broadening of the material choice, improvement of the surface quality, dimensional stability, and achieving the necessary mechanical properties to meet the performance criteria. The current study is part of an ongoing project to adapt fused deposition modeling to fabrication of ceramic and multi‐functional components. This paper presents a methodology of the mechanical characterization of products fabricated using fused deposition modeling.
