Over extrusion in machinery feet – commonly referred to as "elephant foot" in 3D printing – is a pervasive issue affecting both industrial manufacturing and additive fabrication. This defect occurs when the base layers of printed or molded components bulge outward, compromising dimensional accuracy, structural integrity, and assembly compatibility. The problem stems from excessive material deposition during initial production phases, often exacerbated by thermal, mechanical, or software-related misconfigurations. Below, we dissect the root causes, systematic solutions, and long-term preventive strategies to address over extrusion in machinery feet.
