SLM-based tree-shaped supporting unit
The invention discloses an SLM-based tree-shaped supporting unit capable of filling the interior of a part. The inclination angle of branches, the diameter of branches, the branch number of the branches and the stage number of the branches are involved in the tree-shaped supporting unit; the supporting unit is characterized in that the inclination angle theta of the branches is larger than or equal to 45 degrees, and on the premise that the supporting height is not changed, the smaller the inclination angle theta is, the larger the supporting area is; the diameter d of the branches is in direct proportion to the weight of a tree-shaped support, and d is larger than or equal to 0.5 mm and smaller than or equal to 1.5 mm; the smaller the diameter of the branches is, the better the weight reduction effect is; the selection principle of the branch number of the branches is that the branch number of the branches is reduced as much as possible on the premise that the supporting interval of 5mm and the supporting bearing capacity are guaranteed, so that the supporting weight is reduced; and the stage number of the branches adopts a first-stage tree-shaped structure. According to the SLM-based tree-shaped supporting unit, lightweight of SLM manufacturing parts is achieved, materials are saved, and the machining time is shortened; and the tree-shaped supporting unit is simple in structure, clear in force flow and suitable for being used as a primary lightweight tree-shaped supporting unit structure design.
本发明公开了一种基于SLM的可填充至零件内部的树状支撑单元，包括树枝倾斜角、树枝直径、树枝分支数目、树枝级数；其特征在于，所述树枝倾斜角θ≥45°，在支撑高度不变的前提下，倾斜角θ越小，支撑的区域越大；所述树枝直径d与树状支撑的重量成正比，0.5mm≤d≤1.5mm；树枝直径越小，减重效果越好；所述树枝分支数目的选择原则是在保证5mm支撑间隔和支撑承载能力的前提下，尽量减少树枝分支数目，以减轻支撑的重量；所述树枝级数采用一级树状结构。本发明实现SLM制造零件的轻量化，节省材料，缩短加工时间；本发明构造简单，力流明确，适合用作初步的轻量化树状支撑单元结构设计。
