Background:

Additive Manufacturing (AM), or 3D printing, offers design flexibility but suffers from inferior mechanical properties compared to traditional methods.
Inconsistent mechanical performance of AM parts, especially from material extrusion, hinders widespread adoption in critical sectors like aerospace and medicine.

Purpose of the Study:

To review the influence of various AM parameters on the mechanical properties of printed parts.
To investigate the complex interactions between printing parameters and their impact on material performance.
To identify statistical methods for analyzing these parameter interactions.

Main Methods:

Literature review focusing on material selection, path parameters (layer thickness, raster angle), build parameters (infill, orientation), and temperature parameters.

Keywords:

additive manufacturing governing mechanisms in FDM mechanical properties polymers printing parameters

Analysis of parameter interactions and their underlying mechanisms.

Exploration of statistical approaches for identifying parameter influences and interactions.

Main Results:

Optimization of parameters like raster angle and build orientation can improve mechanical properties by up to 60%.
Certain parameter choices, such as material selection, can render other parameters less significant.
Specific parameter settings can alter or reverse the influence trends of other parameters, highlighting complex interdependencies.

Conclusions:

Careful selection and optimization of Additive Manufacturing parameters are crucial for enhancing mechanical properties.
Understanding parameter interactions is essential for unlocking the full potential of 3D printing for high-performance applications.
Future research should focus on further elucidating these interactions and developing advanced optimization strategies.
