Study on unsupported overhangs of AlSi10Mg parts processed by Direct Metal Laser Sintering (DMLS)
Journal of Manufacturing Processes(2015)
摘要
•Geometrical parameters that define an overhang are analyzed with a DoE approach.•α angle, overhang ratio (b/Δx) and curvature (1/R) are significant factors.•A convex surface should be preferred for a large angle.•A concave surface is the good choice for a small angle.•Small overhang ratios lead to better results in terms of tolerance.
