Hello,

So i exported a 3d file from a video game and i'm trying to make it 3d printable

Until know it goes pretty well i think, but in the slicer there is a little hole somewhere that i can't find on my model
I'm using blender

Here're how it is in the slicer, in blender and the printed result

Hard to make it clear through some pics, so let me know if more pics are needed...

Any idea please ?

AI Help

It sounds like you may be experiencing issues with non-manifold geometry in your model. Non-manifold geometry can cause holes or errors in 3D prints. It's important to ensure your model is "watertight" with no holes or open edges.

One approach you can try in Blender is to use the "Select Non-Manifold" tool (Shift + Ctrl + Alt + M) to identify any problem areas in your mesh. You can then manually fix the issues by closing any gaps or holes.

If you're still having trouble, feel free to share more images or details, and I'd be happy to assist further.

I agree with the bot. I've had really bad luck exporting from blender into a slicer

#

I just used some kind of default geometry fixer that prusaslicer pulled from windows to fix it. The sizing was always weird though

#

If you can import it into a CAD program and then export it, it might work better. Otherwise, good luck, it's a bastard of a problem to fix

What is Manifold Geometry
It is important that a model's mesh is manifold in order for a slicer to accurately determine where to generate a tool path to print plastic and where not to.

In relation to 3d printing a model is manifold when you could imagine filling the entire internal volume with water from one source. In practice this means that the model mesh has one single shell with no other shells that overlap or intersect with one another and the shell has no holes in it and the mesh has no flipped normals. You can think of a shell like that of an egg shell, it encloses a single volume of space. If there is more than one shell then filling any one shell the fluid cannot reach the other shells. If shells are nested within one another completely then the volume between the two shells can be filled. If shells partly overlap then only some of the volume of one or both of the shells can be filled. If shells have holes or flipped normals then the volume will leak water.

This service offers a free 3d model repair tools, to fix non-manifold objects (objects with tiny gaps or reversed faces):

The software Microsoft 3D Builder, Orca Slicer and Prusa Slicer can also attempt to repair a model.
