Hi Joe, I'm with the team at NIH. Just a quick note that Chimera exports X3D files, and we provide those for download as well. X3D are typically 1/5th the size of an STL, and you can use them with Cura, or any software based on the Cura slicing engine.

The structures I'm dealing with don't play nicely with the default surface parameters, so the grid size has done wonders. Out of interest, what sort of size would you consider reasonable for printing of a large viral assembly if you were doing the printing? The models currently have about a million and a half atoms, and the STL files are coming out at a few GB at present (hence me wanting to optimise the shrinking and remeshing). Thanks, Joe M.Sc. B.Sc.

We use Chimera as part of our toolchain, so the models will look familiar to you. Check out the “Submit” function of the website to upload a PDB file and get a model in return. Or simply type in a PDB accession code for your model in the “Quick Submit” box to generate a model. https://3dprint.nih.gov Full disclosure: I lead the team that maintains the Exchange.

I'm currently experimenting with MeshMixer's "Reduce" to do the same kind of thing - though I think that will only get me so far. I'll certainly have a look at that walkthrough though. I have just realised part of my problem however, was that I was exporting the surface and ribbon representations though without realising it, rather than just the surface, which would be totally redundant when printed.

Hi Chimera team,
I'm dealing with some protein structures that vary quite a lot in size. I'd like to make 3D printable versions, so I'm exporting STL files.
Is there any way to reduce the file size of the exported STLs? How might one control the level of detail (triangulation) of the exported file - I suspect the defaults are including a lot of detail that a 3D printer wouldn't even be able to replicate in the first place.
Many thanks
