Full spectrum model painter

This is pretty slick, and he's added in a way to map photos onto your 3D FDM models and print with CMY filaments:

Oh - it's also free but he has a donation button to buy him coffee.

Video about it, recommend watching first. Takes a lot of practice.

The resulting models or course are incredibly slow to print, even with a tool changer. I took the crayon tip model I made for the crayon box we print at work, shrunk it down to 3" tall and simply made a fade with 2 colors. The estimate to print is 5 hours 13 minutes (although that's with ABS printing slower) on my H2C - simply swapping between the two extruders which is actually slightly faster than a toolchanger.

I can imagine full 5 color CMYKW prints taking several days, even on the XL or U1.

Indeed, weve all had the dithering idea for multi color printing for years, and since the recent OrcaSlicer implementation, by people way smarter than myself, having discrete pictures on a 3d model was inevitable.

But the technology goes beyond, just pretty pictures. 

Where you can change the properties of, for example, a shoe, that perfectly gives the right amount of  compression by dithering different materials.

The value of this is that it’s for desktop FDM. Jet technologies can do full photographic dithering and a range of soft to hard as a gradient now. That is if you got bucks to pay for it.

Speaking of jetting, here's a display model we did with a company over in Europe. It's printed on a Mimaki, and is about 12" tall. It's so detailed I even put a texture of fluting on the header to resemble the corrugated folded over. I simply took the 3D rendering file I had made in Autodesk Maya and made it watertight (i.e. all one body with no holes in the geometry)  The guy had me on a facetime when I was working with them, he showed me their "press room" and it was wall to wall of those large Mimaki printers, all running. Had to be 5 million worth at least.
