免费 GLB 转 STL
本地把 GLB 转成 STL,用于纯几何 3D 打印检查、切片和制造评审。
先在本地把 GLB 转成 STL,用于纯几何打印准备。
关于这个工具:免费 GLB 转 STL
Convert GLB to STL locally for geometry-only 3D printing checks, slicers, and manufacturing review. 无需上传——全部处理都在你的浏览器本地完成,兼顾隐私与速度。
常见用法
- STL 只保存几何,贴图、颜色、材质、骨骼和动画都会丢掉。
- 转换后请在切片软件里再检查一次。
把 GLB 转成 STL 用于打印
GLB 转 STL 是唯一一个**故意丢信息**的转换:STL 只留三角面,丢掉颜色、贴图和材质——因为切片器要的正好就是这些。永远从你生成的 GLB 转,别拿一个已经被转过一次的文件再转。
能省掉一次废打印的顺序
- 1
先确认这个模型能打印
转换之前,先用检查器打开 GLB 看底部。壳不封闭、或者壁厚小于两个喷嘴宽度的网格,转成 STL 之后照样不能打。
- 2
在浏览器里转换
转换在本地完成,未公开的模型不会被上传,也不需要账号或积分。
- 3
单位在切片器里去设
STL 不带单位。在切片器的模型信息里读毫米制包围盒、和实物对一下,再据此缩放,不要靠猜。
GLB 转 STL 常见问题
- GLB 转 STL 会丢贴图吗?
- 会,而且是故意的。STL 没有颜色、材质和 UV 通道,导出只有几何。把 GLB 当母版留着,STL 当一次性派生文件。
- STL 的单位是什么?
- 没有单位。数字是无单位的,所以只有你告诉切片器这些数字代表什么,文件才是正确尺寸。先在切片器里按毫米确认包围盒。
- 能从 STL 把贴图找回来吗?
- 不能。只能从原始 GLB 重新导出;否则颜色得手工重做。
小提示
- STL 只保存几何,贴图、颜色、材质、骨骼和动画都会丢掉。
- 转换后请在切片软件里再检查一次。
