# 3D 切片软件

### 什么是 FDM 3D 打印中的切片器？

切片器是一种专用软件，可将 3D 模型转换为适用于 FDM 打印机的可打印指令（G-code）。它会把数字设计“切片”成水平层，计算运动路径，并定义打印速度、温度和材料流量等参数。切片器能够对打印质量、材料效率和结构完整性进行精确控制。

### 切片器如何工作

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）将模型分成各层。
3. **路径生成**：映射挤出机的运动，包括填充图案、支撑和附着辅助。
4. **参数配置**：调整喷嘴温度、回抽、冷却以及材料特定设置。
5. **G 代码导出**：为打印机生成机器可读的指令。

主要功能包括 **填充密度** 优化， **支撑结构生成**，和 **打印速度调整** 以平衡质量和效率。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.polymaker.com/polymaker-wiki/polymaker-wiki-zh/ji-chu-zhi-shi/3d-slicers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
