It would be nice if additional colours would be supported, à la Hexachrome by Pantone (this was a 6-colour ink system which covered more than half of the PANTONE spot ink colour space and made quite vivid photo reproduction possible).

Even better would be a mechanism like to Cerilica's Truism which would allow one to use arbitrary filaments and preview how they will blend when printed.

They’re not limiting you, the community work this is based on doesn’t either. Yeah they’re going to sell sets for easy use but it’s just color mixing. If you know the filament colors, which is what the filament database is for, you’ve got all the info you need.

And you’re only limited in quantity by how many filaments you can load at once. A full INDX setup on a Core One is 8. I thought you could daisy chain Bambu AMS units on their printers, which would let you get your 16 maybe? I’m not very familiar with their offerings.

The newer Bambu printers (H2D and X2D) allow up to 25 colors. One nozzle connected directly to the spool holder, then the other to four 4-spool AMS 2 Pror and 8 single spool high-temp AMS HT

Oh I didn’t know they had 8 spool models. Thanks for replying with the correct details.

I’d hate to see the cost of all that though.

primed3d can do photos onto models. still limited by print resolution, but very cool concept.

Photo reproduction should be the target here...

And it looks like the software support needs work too - the obvious way to do it is being done able to import a jpeg or png to project or wrap onto the surface, a bit like texture maps in video games.

There's an app called Hueforge that produces models that color mix to reproduce photos:

It's been around for years. There are databases of filaments with their TD values and color measurements to use. The blog really sells Prusa's attempts to do this with their own PLA, but there's a long history of color mixing in the community with extensive measurements of filaments that anyone interested should check out, too.

[WillAdams]

That looks/feels a lot like the Cerilica Truism approach (arbitrary mixing).

Will have to keep it in mind for when I get a printer which does nozzle/toolhead switching.

[Aurornis]

You can use it with any printer if you're willing to swap the filaments manually.

The print file will have pauses inserted at the layer swaps. You manually swap the filaments when it pauses. There are only a few layers and colors so it's not too hard.

[WillAdams]

I have a printer with four filament changer --- my predilection for this is mostly a concern for waste --- plus, I want a 4th 3D printer....

[ant6n]

I thought Prusa only has a five color print head switcher.

[Filligree]

The XL? Yes, but they also have an eight colour nozzle changer.
