# 3D 切片软件

### FDM 3D 打印中的切片器是什么？

切片器是一种专用软件，将 3D 模型转换为适用于 FDM 打印机的可打印指令（G-code）。它将数字设计“切片”成水平层，计算路径，并定义打印速度、温度和材料流量等参数。切片器可实现对打印质量、材料利用率和结构完整性的精确控制。

### 切片器的工作原理

1. **模型导入**: 接受 3D 文件（STL、OBJ、STEP 等）以定义几何形状。
2. **层分割**: 根据用户定义的层高（例如 0.1mm–0.3mm）将模型划分为层。
3. **路径生成**: 映射挤出机运动，包括填充模式、支撑和附着辅助。
4. **参数配置**: 调整喷嘴温度、回抽、冷却和材料特定设置。
5. **G代码导出**: 生成供打印机读取的机器指令。

关键特性包括 **填充密度** 优化， **支撑结构生成**，和 **打印速度调整** 用于在质量与效率之间取得平衡。
