I’m on a roll against huge STL file sizes! You can look back at some of the past story here, but in summary I have a complex section of a design that started off being a collection of separate truncated octahedron parts. When saved as an STL, the file size was 259MB, which for something only the size of an Up! Plus 2 print plate, was pretty ridiculous.
It took me a lot of mucking around but eventually I reduced the STL file size by merging all those separate parts to form a single solid within Solidworks. That’s the 104MB pictured above.
Now I have just discovered the freely available MeshLab software, which in a matter of seconds has simplified the mesh to half the file size, without compromising quality. Now if you’re a 3D printing nerd like me, that’s cool! I’m sure with tweaking this could be further reduced, which is important since the part I’ve been testing is only a portion of a larger product, and I need it to be less than 100MB for uploading to i.Materialise in the future.
Looks like MeshLab does a whole range of other things like repairing meshes and cleaning up textures, so if you’re slow like I obviously am, download MeshLab now!
