Different color infill and walls

[ndoty]

I’m printing, or getting ready to print some parts using clear pla. I’d like to do the outer walls with the clear but use a colored infill. I would like the walls all clear, so no layer color changing etc, but using the ams to put a colored infill in. I can’t find any option to do so,

Am I missing an easy to find option, cuz I bee dum, or am I looking for something that doesn’t exist?

There isn’t an option that I know of but this can be done using modifiers.

Can you point me in a direction to read up on this? I have a pair of enders at home and I think I can do it, as long as Im willing to spend the rest of my remaining life standing by and changing filament. I have a bambu with the ams at our makerspace.

Edit:

Is this what you’re talking about?

I love Modifiers!

Does anybody use modifiers in the Orca or Bambu slicer? I learned about them kind of by accident. I was printing a bambu plate holder and when I saw it printing the infill, I thought I was looking at support structures within the infill, later I realized that they weren’t supports, but were just slits to accommodate the part that sticks out on the plate where the nozzle cleans itself. But before I realized that, I wanted to figure out how to make supports within the infill so I could make str…

Same here. And I fear that modifiers are only an option for very simple shapes like a cube, rectangle or sphere by using a scaled modifier in the same shape as the original model. However, even something as simple as a Torus or Banana would defeat this however as the radii chage, leading to different wall thicknesses.

Other than spending a good amount of lifetime by manually editing the exported gcode to add filament changes between walls and infill (and back again) and printing from the SD Card, I do not believe that there are many other current options. Nevertheless, the gcode usually contains a description such as “;FEATURE: Sparse infill”. So it should be possible to use a Macro to do the editing for you.

I’m very much a hobbyist who can make the machine (usually) work, going line by line and trying to edit every layer sounds to be a bit beyond me. I was reading the thread I posted, and it doesn’t seem to lead where I am hoping to go.

There may not be a path for me

That’s what I thought years ago. But it is actually much easier than it sounds. Still, 3D printing can be a bit like driving: If in doubt, don’t. No (longer) dangerous, but repeated failures can quickly take all the fun out of it. Once you are more comfortable with the printer, software, etc you can always come back to a prior challenge.
I still have some on my todo list from the last decade

I’m entirely too buys finding new and exciting ways to screw things up on my cnc machine to learn how to do it on the printer :laugh:
