象脚缺陷

Definition

象脚是一种尺寸打印瑕疵,表现为最初几层周围出现外扩、鼓起的底部,成因是喷嘴向下压力、偏低的首层 Z 偏移,以及过高的打印板温度使底部塑料保持半熔融状态。

Cost Impact

象脚意味着打磨或重打底层——这是大多数报价遗忘的隐性人工。尺寸缺陷会直接转化为后处理成本。

底层鼓起的根本原因

当首层时喷嘴离打印板太近(初始挤压过度),或当加热床温度设置高于材料的玻璃化转变温度时,后续层的重量会把熔融的底部向外推挤。

切片软件的缓解措施:首层补偿

现代切片软件提供专门的补偿设置——如 首层水平扩展(Initial Layer Horizontal Expansion)(例如 -0.15 毫米到 -0.3 毫米)或 象脚补偿(Elephant Foot Compensation)——自动内缩首层几何,确保垂直壁面笔直。

硬件调平与热校准

精确调整自动 Z 偏移,并在首层后降低打印板温度,可确保良好的打印板附着,同时避免难看的尺寸外扩。
