This method makes the printing time increased to 3 or 4 times the original. The amount of materials used is also 4 times. It also makes printing harder to success.
Now I find a way to improve this, but need a little modeling skills.
In short, the approach to problem-solving is Make a smaller model, and boolean difference with annual ring modifier, then slicing.
This time I use a cube for demonstration
make a 606060 cube.
make a 595959 cube, move it to inside the bigger one.
select the modifier, click mesh boolean-difference
Subtract from the modifier, substract with the 595959 cube
waiting… the boolean operation may lead to some mistake, like non-manifold edges, try to fix it, if failed to fix, it also doesn’t matter.
keep the parameter refered to the last topic, top layer 90degree rotate, fuzzy skin to the ex-walls.
So, you may need to make change with the origin model. Inward offset it with about 1mm distance. This step need some modeling skills.
Import it and doing boolean operation. Save much more time!
Latest information, due to the frequent failure of the boolean function for complex meshes, this method cannot be called perfect, it still needs to improvement.
The Tree annual rings mesh is very complex, with a simple model may lead to boolean failing. If model is also complex, boolean operations are almost certain to fail.
PanDan, I’m in the middle of a project where I need to apply fine wood grain to multiple objects in a lamp design I’m 3D printing. I have printed multiple samples of components using your approach but the print times are way too long. The shapes I’m printing are more complex where inserting a smaller offset object inside would not be possible. I’ve also tried doing this in blender but that adds a whole different level of complexity to get grain scaling and direction set properly. I’m ripping my hair out over this. Have you made any additional progress on improving print times do you have a less complex modifier mesh that would help print times?
You can use the latest Bambu Studio or beta version, I forgot which one I need. The latest fuzzy skin effect will not break the exterior walls. It helps to reduce time and has a different effect.
That would be great!! I’ll look into which version adds improvements in fuzzy skin performance. Is there any change in your process that comes along with this? Still 100% infill? Thanks for follow up!
