the texture file

[cam3d]

Other than computational hydrographics (https://formlabs.com/asia/blog/full-...hydrographics/) I'm not aware of anything similar. I think part of the issue is ink flow and gravity, pressures etc... much harder to implement than conceptualize

Many thanks for the examples and pointers

Looks like it raises another bunch of questions...

but I guess the main question is whether

there exists a product that can simply apply colour to a model/object no matter how it was produced

whether by 3d model, plaster mold or cnc carving

something like an automated paint spray?

Something to note - On the shapeways configurator, you need to select 'SANDSTONE' at the bottom of the material options, which opens up the choice between 'Plain' or 'Full Colour' - Or you could just go for the Multi-Colour Polyjet if you're after super high quality and price is no object: https://www.shapeways.com/materials/multi-color-polyjet

roger johnson - Are you looking to apply a texture to a 3D print?

There are several printers which can print a full colour model - The one I am most familiar with is the ProJet 660 (https://www.3dsystems.com/3d-printers/projet-cjp-660pro) - It's been several years since I operated one of these but they are classed as colour jet printers and give OK results.

You can find this printer as part of Shapeways selection - Simply export as .OBJ with UV texture and MTL file, zip all up and upload to their configurator

Here's a sample ZIP I made for you: https://drive.google.com/file/d/17HO...ew?usp=sharing

NOTE: This is an expensive production process! You might be able to find a cheaper vendor locally, however colour 3D prints are notoriously pricey.

Newbie: Its probably a really dumb question but

are there devices that can apply the texture file during or post output of the basic model ...

something like an ink jet ?

If so, could you suggest a suitable tutorial?
