Design tips for parts that warp while printing (FFF/FDM)
When printing with fused filament 3D printers, some parts have a tendency to warp.
Here are a couple different design strategies for overcoming part warping while printing. When melted plastic is extruded it expands, then contracts immediately as it cools. Most warping starts at the corners near under cuts and overhangs. This is especially ture with materials that have higher thermal expansion cooefficents such as ABS. Designing parts with vertical curves (filets) is one
