If you chose to do different filament you may get slightly different color gradients. You can do create this in any printer that has a 225mm bed or larger. If you plan to scale the model make sure that you are only scaling the X and Y, NOT the Z.

Commercial use? I wouldn't sell this one as I just found the image online, and they did not have an artist attributed to it. This is more of a Demo on what can be done.

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

Filaments Used:
PLA PolyLite Black Transmission Distance: 0.3
PLA PolyLite Wine Red Transmission Distance: 1
PLA PolyLite Orange Transmission Distance: 3.5
PLA PolyLite Lime Green Transmission Distance: 3.5
PLA PolyLite White Transmission Distance: 7

Swap Instructions:
Black until layer #8 at 0.72mm
Wine Red until layer #9 at 0.8mm
Orange until layer #18 at 1.52mm
Lime Green until layer #28 at 2.32mm
White for the rest.

Please share your makes!
