Slic3r

Slic3r 是将 3D 模型转换为 3D 打印机打印说明所需的工具。它将模型切割成水平切片（层），生成工具路径来填充它们并计算要挤出的材料量。

Slic3r 项目于 2011 年在 RepRap 社区内诞生，旨在为不断发展的 3D 打印技术提供开放而灵活的工具链。代码和算法不基于任何其他先前的工作。代码的可读性和可维护性是设计目标之一。Slic3r 是一个真正的非营利性社区项目，它允许人们尝试几个后来变得很常见的原始新功能，例如多个挤出机、边缘、微层、桥接检测、命令行切片、可变层高、顺序打印（一次一个对象）、蜂窝填充、网格切割、对象分割成部分、AMF 支持、避免交叉周长、不同的挤出宽度、修改器等等。所有这些功能都是在 Slic3r 中首次引入的，现在已成为商业软件的一部分。

Slic3r is the tool you need to convert a 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.

The Slic3r project was born in 2011 within the RepRap community as an effort to provide the growing 3D printing technology with an open and flexible toolchain. The code and the algorithms are not based on any other previous work. Readability and maintainability of the code are among the design goals. Slic3r, being a true non-profit community project, allowed the people to experiment with several original new features that have become common thereafter such as multiple extruders, brim, microlayering, bridge detection, command line slicing, variable layer heights, sequential printing (one object at time), honeycomb infill, mesh cutting, object splitting into parts, AMF support, avoid crossing perimeters, distinct extrusion widths, modifiers, and much more. All of these features were first introduced in Slic3r and are now part of the commercial software out there.
