One approach is to just print CMYK resin like an inkjet printer (and then cure it with UV).

Do that hundreds or thousands of times and you eventually get Z height.

Look up the EufyMake E1 for a consumer/prosumer version.

The EufiMake isn't really a 3D printer though. It's more a normal printer that can do an embossed/textured print.
