I’ve learned that I could take a .jpeg file and load it into the Cura software that came with the 3d printer (Ultimaker 2) and it would add depth to the picture. I had the option of letting either the dark or light colors to have depth.
I selected one of my pictures that I took at the Holy Family Shrine.
I had to scale down the image to 4″ x 6″ in the Cura software because 1101.3 x 1468.5 mm (43.35 x 57.81 inches) was too big for the printer.
I believe the results were amazing.
