3D models are usually composed of three pieces of surface, for some large models, due to the limitations of the printer itself, it is impossible to print out very small details in the model. And these large models often take a long time to slice.
You can use the "Simplify model" feature to reduce slicing time by reducing the number of triangles by a certain amount.
You can reduce the number of triangles in a mesh using the Simplify mesh feature.
Right-click the model and pick ”Simplify model“ from the context menu.
Check "Show wireframe" to view the white outlines of each triangle face. You can adjust the "Detail Level" for coarse adjustments to the model or use the "Decimate Ratio" to finely adjust the model from 0-100%, significantly reducing the number of triangle faces.
