This study aims to investigate the influence of 3D printing parameters, specifically using the Fused Filament Fabrication (FFF) technique, on the mechanical characteristics of produced parts. The analysis involved examining 495 printed samples, with variations in key parameters such as extrusion temperature, print speed, density, infill geometry, layer height, and the number of walls.

Main Topics Covered

In this whitepaper, we will cover:

• Infill Type: The Grid infill is hypothesized to offer superior strength compared to Gyroid and Triangular infills due to its interconnected grid structure.
• Infill Density: Higher infill density is anticipated to contribute to increased mechanical strength, as more material within the part should enhance its ability to withstand stress.
• Layer Height: A lower layer height is presumed to adversely affect mechanical strength due to weaknesses in adhesion between layers.
• Print Speed: Elevated print speed is predicted to result in decreased part quality due to extrusion instability and less effective bonding between layers, potentially weakening mechanical strength.
• Print Temperature: A higher temperature range is expected to improve bonding between layers, thereby enhancing the mechanical strength of the parts. Conversely, lower temperatures might result in cold extrusion with material loss.
• Number of Walls: A higher number of walls is suggested to significantly increase the mechanical strength of printed parts, providing greater structural stability.
