Review on multi-objective optimization of FDM process parameters for composite materials

3D printing is a process used in many industrial sectors like automobile, aircraft, buildings and several medical fields to fabricate products.Fused deposition modeling is a type of 3D printing processes also known as fused filament manufacturing. Two main response parameters must be considered when using FDM to manufacture parts: Part strength and dimensional accuracy. Though FDM is a popular method for producing complicated geometric products in a less time, it has limitations, including poor mechanical characteristics and dimensional accuracy. An extensive review is carried to know the influence of following process variables on mechanical characteristics such as Thickness of layers, Printing speed, Extrusion Temperature, Infill Density, Infill Patterns, nozzle Diameter, raster Angle, build orientation. It is crucial to choose the best possible combination of process parameters. The FDM process parameters can be optimized using a variety of strategies. As a result, a comprehensive review has been presented on pre-processing to examine the characteristics for printed parts. The two components of study are critical for increasing overall characteristics, i.e., improving functional utility and enriching the uses of FDM printed parts. The current report meant to provide basic assistance and guidance to researchers working on the subject of FDM Process Parameters.
