Exporting Colors via 3MF Files
I'm wondering if it's possible to preserve color information from the
original model in a file exported in 3MF format (which supports color
information). Colors are normally lost during rendering, so probably not.
Assuming that can be done, does anyone happen to know if Simplify 3D can
use model color information to select which print head to use?
This would give me a much simpler (and less error prone) workflow for
multicolor prints.

IDK.
I dont think so - at least I have never seen an option for that. Based on
the tutorial that S3D has for multi-color(
https://www.simplify3d.com/support/articles/printing-with-multiple-extruders/)
I doubt it. You should ask them this question though - they are very
responsive, and it would make 3D printing multi-material suck a lot less.
Oh yeah.

Is it possibly to preserve colors added to a model when exporting to 3MF?

As I recall from the last time this came up, it is rather unclear what to
do when volumes of different colours are unioned together

Also in preview you can have different coloured faces on the same volume,
which doesn't really fit in with most types of 3D printing.

That's an excellent point. Preview seems to handle this, but the behavior
probably gets weird in cases I just haven't noticed yet.

Some time ago I made a script to help with exporting OpenSCAD models as
colored AMF. Perhaps that can be a starting point for colored 3MF export.
Basically, the script analyses your model to figure out which colors it
uses, and then makes OpenSCAD do a separate render for each color, with only
the geometry in that color. Finally all outputs are combined into one model,
with added color info.
It uses the oystrich approach to deal with weird geometry issues, so it's
probably best to avoid overlapping colors and such in your model...
Yep, AMF is not quite the same as 3MF, but the general approach should work
too hopefully :)
Maybe I can sneak in a proper lib3mf-based merge step, will have a look
later this week.
Incidentally, I made that script to produce an AMF for browser display
(using three.js). I have a hard time finding any regular tool that will
display the colored AMF files properly, let alone any slicer... :(
Script can be found here: https://github.com/jschobben/colorscad

Very cool! I'll try and take a look at your script later tonight.

Short update: the ColorSCAD script now supports 3MF as well!
It cheats a bit though, by using a c++ implementation to do the merging
step (based on Lib3MF). As a result, some compilation is needed to get
3MF working, and it requires 2019.05 as well.
It's still here: https://github.com/jschobben/colorscad

True, but a warning message would be sufficient there.
Remember, everything isn't 3D-printing.
