Texture mapping with feltpen carousel?

Build a Delta printer onTop of my CoreXY and attach an effector that holds the feltpens and solenoids. (No carousel required)
The carousel sounds easier, no?
Yes, but the colour saturation is so much better when we ink the already printed part. And that requires some extra tool axis'

Not much of a braincrunching project (which is usually most of the fun), but a decent option to texture 3D prints could be hydro-dipping:
It can do wood grain nicely.
Requires a suitable inkjet printer, hydrodipping sheets, activator and a bucket of water. I never actually did it, but maybe I might someday.

@DaBit
Looks good too.
I'm also sure there are SLA printers which dye every layer with an inkjet, but they don't fit in my budget. -
Sure, directly painting the surface makes sense. How to get decent resolution is a good question. Inktjet gets you there. Felt markers, meh.
For occasional use hydrodipping might just be the answer. Standard patterns are available as rolls, custom can be done with blank sheets and an inkjet printer (but not any inkjet).
I might want to try it one day. UV-unwrap the object in Blender and use hydrodipping to transfer graphics to a printerd part.

Just found a new playground for feltpen-layer inking:
I made some monochrome Lithopanes and realized, how easy it would be to add some colour by inking just the right places between each layer.
Finally a green Yoda Lithopane

I promised you a carousel, but here is a draft of a different way of toolchanging.
The red tool is active, the crossbeam can move along the bed.
When the crossbeam parks between the curved "OpenV-extrusions" the tools can trade places. Imagine the whole rear area is full of parking tools.
They all have their own motor, geared like the Hitchhiker, but running on rack and pinion.The curved OpenV profile is printed, there is no need for a tight and accurate guideance. Only the crossbeam is the real stuff.
I hope you get my intention...

for your research
@o_lampe, did you try with natural translucent filament?

@fma
I bought white filament, before I knew...and I guess with the "direct inking" I'm planning, it is the better choice. -
@o_lampe Painting on printed part is not easy: ink tends to diffuse along the layers...
I also made some tests with a black inkjet cartridge, but the ink does not stick to the PLA... I think it would require to find the correct ink, which stick on printed part, and compatible with inkjet head (I tried aerograph ink, but it jammed the head!).
I think inkjet is better with powder 3D printing: https://3dprintingindustry.com/news/build-3d-printer-uses-powder-ink-jet-technology-31951
I plan to make tests with pens, as Make Anything did; it is a very easy setup...

I already figured out, only 'permanent markers' stick to PLA.
I think, I've seen the video and their process is not able to produce real textures.
You'd have to dye the filament with a timed process. I'd better like to steal the mapping algorhythm from "velocity printing" and rewrite it to add ink layer by layer.
I don't expect perfect results, but a powder printer with inkjet is a bit above my budget..Let's see how bad it is..
