Abstract

Fused Filament Fabrication (FFF) is a popular additive manufacturing process where parts are built as a superposition of flat layers of material. The nature of this process allows for the use of more than one extruder within a single layer. This means that FFF can be used under a multi-extruder architecture which enables the manufacturing of multi-material parts. Examples of this type of parts can be found in mechanical and bioengineering fields. When designing this type of parts, bonding between different materials becomes a key issue, since the intention is that the part works as a whole while advantage is taken from dissimilar properties of materials. One of the main goals in this type of analysis is to determine the resistance that the part shows in the frontier between materials. This work aims on the analysis of failure behavior of bi-material FFF joints.
