Cài Đặt (Installation)#
Trình Bổ Sung này được đóng gói cùng với Blender.
Mở Blender và chuyển đến Cài Đặt Sở Thích, sau đó đến thẻ Trình Bổ Sung.
Click Mesh then 3D Print Toolbox to enable the script.
Miêu Tả (Description)#
Blender can be used to created meshes for 3D printing. Meshes exported from Blender are usually imported into a piece of software takes the mesh and "slices" it into paths that the 3D printer can execute. An example of such Slicer software is Cura.
In order to correctly slice a mesh, it needs to be "watertight", meaning that the surface is closed everywhere. Additionally, there should be no edges or faces sticking out. 3D Print Toolbox helps you analyze problems in your mesh that could cause slicing issues.

Phân Tích (Analyze)#
Thống Kê (Statistics)#
By clicking either Volume or Area, the volume or area of the mesh is calculated and shown.
Kiểm Tra (Checks)#
Bảng Kiểm Chứng.#
A number of different checks can be performed to analyze in which ways your mesh might be invalid for use with a Slicer.
Upon execution of one of the checks, the Result field shows which, if any, parts of your mesh are invalid.
When in "Chế Độ Biên Soạn", clicking these results selects these parts of your mesh. You can use "Hiển Thị cái được Chọn" Dấu Chéo Ngược (Backslash) to focus on these parts.
Although Slicers are becoming increasingly tolerant when it comes to "tidiness" of meshes, it is always worth trying to provide as clean a mesh as possible.
- Lập Thể (Solid)
Checks for Non-Manifold edges and Bad Contiguous edges.
Edges should connect to exactly 2 faces. In it connects to only one, it means there's a hole in the mesh. More is also not allowed. These edges are considered Non-manifold. If one of the faces' normals is pointing in a different direction than its neighbors, its edges are marked as "Bad Contiguous".
In this screenshot, the left shape has a hole, and the right shape has one of its faces flipped.
Left, marked in blue: Non-manifold edges. Right, marked in red: Bad contiguous edges.#
- Giao Cắt (Intersections)
These two cubes have intersecting faces. A Boolean modifier would help in this example. It's worth noting that some slicer applications can deal with this, so it's not always required to resolve this issue.
- Suy Biến (Degenerate)
Faces and edges which have 0 area or length, are considered degenerate. In this example, the top face of a cube has been scaled down to 0, but have not been merged. A would resolve this issue.
There's a hidden face here.#
- Biến Dạng (Distorted)
The vertices of a quad or ngon can be folded in such a way that the face is not flat. In practice, quads are rarely ever flat. When exporting, these faces are converted to triangles. If the surface is excessively deformed, this can result in unexpected shapes.
In this example, a quad has been folded into a saddle-like shape. This triggers the Distorted check. It would be best to triangulate by hand here.
This quad can triangulate in unexpected ways.#
- Độ Dày (Thickness)
Faces that form very thin geometry might be missed entirely by the slicer. Such faces are marked as Thin.
- Cạnh Sắc Nhọn (Edge Sharp)
Similar to Thickness, sharp edges can thin pieces of geometry which might be missed by the slicer
- Nhô Ra Lơ Lửng (Overhang)
As 3D printers can't print in mid-air, parts of the model which overhang will not print correctly. In practice, slicers can add additional material, support, to anticipate for overhanging layers.
- Kiểm Tra Toàn Bộ (Check All)
Performs all of the above checks at once. In this example, Suzanne shows quite a few problems. This is because the eyes are separate parts, and the sockets have holes. This makes the mesh not Solid and Intersecting. Some of the faces are Distorted.
Dọn Dẹp (Clean Up)#
- Biến Dạng (Distorted)
Triangulates the faces which are considered Distorted, as explained above.
- Đa Tạp Hóa (Make Manifold)
Attempts to fix various problems which might make a mesh non-manifold, such as by fixing bad normals, filling holes, and removing empty edges and faces.
Transform (Biến Hóa)#
Đổi Tỷ Lệ thành (Scale To)#
- Âm Lượng/Thể Tích (Volume)
Scales the model to an exact given volume.
- Ranh Giới (Bounds)
Scales the model so that the biggest axis of the objects bounds (or dimensions) match the given value.
