Study on the effects of raster spacing and raster angle on the mechanical properties of FDM-printed parts

Key Points

• The aim is to investigate how raster spacing and raster angle affect the mechanical properties of parts made by Fused Deposition Modeling (FDM).
• Conducted experiments on FDM-printed samples with varying raster spacing and angles.
• Measured mechanical properties such as tensile strength and stiffness.
• Analyzed results using statistical methods to determine significance.
• Identified optimal raster spacing and angle for enhancing tensile strength.
• Showed that different raster angles significantly influenced stiffness.
• Found that certain configurations led to the best overall mechanical performance.
