Hi, I’m an art student and I’m developing my own line of 3D printed brooches. I’m going for a realistic representation of various body parts images, such as eye, lips, nose, etc (I’ve attached an image as reference), so the prints would need to be multi-colored. Which 3D printing technique would you recommend for this?

Hi !
That’s a cool project.
You should print them with a Polyjet 3D Printer.

Love your project @annacz94, and I looove brooches 
so can’t wait to see the final version!
In the mean time, feel free to read about the different 3D printing technologies here, to decide which would be the most suitable: What is 3D printing? How does 3D printing work? | Hubs
You would have to go with a dual extruder printer… if not for that I would suggest a DLP resin printer

To get true realistic color ramping is difficult with traditional 3D printers; you can go powder/composite route but the colors tend to be a little muted/toned down and the items are still extremely fragile even after dipping and treating with Cyanoacrylates/Superglue… using DLP resin prints would produce very nice models but no color and you would have to prime/paint each model accordingly or look into some testing with high quality hydrographic films to get the color transferred to your model.
Depending on the forms and undercuts you might look into the new color/paper 3D printer Mcor ARKe.
You can get full color ramping and once the element is treated it’s essentially a solid block of paper/wood.
