Brief Overview Over Fused Filament Fabrication Infill Parameters

Abstract Fused Filament Fabrication (FFF) is an additive process manufacturing based on the deposition of thermoplastic material on a heated plate to produce a three-dimensional part. FFF manufacturing technology creates parts with complex geometries by overlapping material layers. FFF technology is used in various fields to produce physical mock-ups and functional parts. This article focuses on the infill process parameters available in the UltiMaker Cura software. Based on the Ishikawa method, seven parameters directly related to infill were identified. These parameters present other subcategories of parameters, resulting in a total of 41 parameters which can be found in the following slicer’s parameter sections: quality, infill, material, speed, special models, supports, and experimental. These process parameters influence many characteristics of the resulting parts, such as the aesthetic, material consumption, which further influences the production costs and the manufacturing time.
