From VRML multicolor to multiple STL?

Hi everyone,

I’d like to print a 3d volume which surface has gradient colors from red to blue :

Block Image

(this is the electric charge mapped on a molecule surface)

The scientific software generating this visual can produce VRML (.wrl), which is accepted by high-end 3d printers with dedicated slicers (like Stratasys for exemple). However, I’d like to find a way to print it with our Raise3d+Palette 3.

Any hints or advices ?

Hi Hana,

Well… the issue is not only to get a single .stl for the global volume but to get subsets .stl associated with the right colors…

Or any other workflow that would fit Mosaic Palette.

You might be able to get passable results using the stamp tool. Load in the model in single color then load a top down image of the coloring as a stamp on top of the model. It's tricky to align, but might be a workable result
