I have been trying to convert an assembly to VRML format to 3D-print a model but when I do it in the most obvious way (save a copy-save as type-*.wrl), the assembly is broken in to several files relating to the assembly components and cannot be opened.
Similarly, when I do the same for single parts, the file does not open properly either.
I have also tried to convert it as an *.obj but this removes the colouration and reduces the polygon-count of the model when I open it in the printing programme.
Could anyone make a suggestion as to how to solve this?
You might consider .STL since that is the native format for most stereo lithography tools.
Only solids will be converted. Not sure how assemblies will be treated since, by definition, each part should be a single "item" within the assembly. You might consider making a shrinkwrap model to get everything into a single "blob".
