CAD for multiple colors  

RE: CAD for multiple colors

For multi-material printing, you need multipart objects. The resulting parts have to share the same coordinate space.

You can also split single-part objects into multi-part using PrusaSlicer v2.4 or higher.

Thank you very much for the video.  I am trying to duplicate it.

Would the advice given for Fusion 360 be applicable in concept for FreeCAD?

CAD is CAD. Other tools, but the result should be the same.

Thanks for the link, looks like something I need to look at.

RE:

I am making poker chips. I used AutoCAD for design because I'm so old it is the only thing I know how to use.

Each color is it's own object. So, every time I used black those singular black objects had to be prepared in AutoCAD as if they were all one object. Each white color had to be combined into it's own white object and so on.. And then those 5 objects had to be placed to share the exact same center point, or else the different objects would never print as one whole multicolored piece.

I had a weird thing happen where my red objects looked correct in AutoCAD but they was flying out far away from my poker chip... whereas all the other colors were properly printed as they should. So, above my poker chip I printed a simple layer that contains every color in a square. Somehow, that simple multicolor square that has nothing at all to do with the poker chip stops the colors from getting printed in nothingness, away from the whole piece. I think AutoCAD has so very many decimals and a math error at a tiniest move projects the clocking out into weird and crazy places. For me, printing a useless square above my poker chip made my objects print where they were supposed to go.

And finally, the slicer uses one tool for each object as you assign. Therefore, each tool is a different color. And with all colors of objects having the same point as the shared common center point, you will print a single multicolored part.

If you can drive Autocad, particularly the older versions, FreeCAD should be very easy to pick up.

There are all kinds of tutorials for doing multi-color in FreeCAD.  Just do a Google/DDG search and you will find.

I pre-ordered with 5 heads, but i don't know how to design for multiple colors.  Does anyone have any information or guidance?

It's no longer necessary to do your color separation in CAD; Prusa Slicer 2.4 includes multi-material painting.
