Hi everyone,
I have a student that has ventured into the solid tools of Rhino 7. I am not familiar with it at all as we’ve just started using 3D printers at my school. He has a multicolor file that we are trying to export to Bambu Studio in its 4 colors: black, white, red, and yellow.
We’ve tried the export/import menus of the two tools with no success. How should I direct him next? Thank you, in advance, for your help.
Multi Color Union.3dm (7.1 MB)
export the colors as separate parts, import them one by one into Bambu, then right click and set the filament per part.
fwiw, these parts are not correct to my eye.
looking deeper into this file… they are asking for a very long print as this sits.
they’d be better served making these pieces snap together instead of overlap and print them as parts that assemble like a model kit.
as it sits you are going to have to purge filament 3 times for each layer that is going to add a very very long time to your print.
My advice is to print the red as one whole part, print the white as one whole part and print the yellow as one whole part, then snap or glue them together at the end and.
Also notice that the white and yellow under the word “union” are not trimmed correctly, but over lap significantly, this is not a good idea, better to trim them correctly to be edge to edge.
also your white pegs poke thru the surface in all 3 locations. I’d trim those so they are cleaner or union them with the yellow part.
type the commands in the commandline - or check the help
_mesh with 0.01 Edge to Surface tolerance
_selMesh
_export → (a single)* Stl with multiple meshes is ok for export and will keep their position bambulab
in bambulab drag & drop the .stl
then add/set all colors/filaments (first !!)
change to object-process
split the import file to objects
assign the filaments (only visible if there is more then one)
but best is to print separately per color and stick / click / glue together afterwards as Kyle wrote.
if you want to use colors: as there is not much detail in z-height use a thick layer height.
hope this helps - kind regards - tom
*EDIT: added “single” - use one stl file for all your objects !
Thank you Kyle. I really appreciate the time and thought for your reply. I’ll let my student know and work with him to make these changes.
Thank you Tom! This video is wonderful. I really appreciate you and Kyle jumping to our aide so quickly. I’m really excited to learn more of Rhino’s capabilities. I’ve dabbled in TinkerCAD, but I haven’t tackled 3d work in Rhino, Blender, or Fusion 360 yet.
Yep, just like a model maker would do. All that wisdom embodied in the real world : )
The workflow we use is to export to .step, right click on the object and split to parts, then if you switch the process slider from global to object you can change the filament per sub object. But yeah in this instance it may be easier to print separately and assemble. 0.15mm tolerance is your friend for anything that plugs in.
Edit just to clarify why this is necessary vs Kyle/Tom’s methods - Bambu will drop objects down to the bed if they’re imported separately or split to objects, so to keep things in their correct (Rhino) position, you need to import together and only split to parts.
because of the “drop to buildplate” i wrote:
Your method works until the split to objects stage, which will also drop the objects to the build plate. You need to split to parts to avoid this.
