Police asked this 3D printing lab to recreate a dead man’s fingers to unlock his phone | Fusion

“We don’t know which finger the suspect used,” he told me by phone. “We think it’s going to be the thumb or index finger—that’s what most people use—but we have all ten.”A 3D printed finger alone often can’t unlock a phone these days. Most fingerprint readers used on phones are capacitive, which means they rely on the closing of tiny electrical circuits to work. The ridges of your fingers cause some of these circuits to come in contact with each other, generating an image of the fingerprint. Skin is conductive enough to close these circuits, but the normal 3D printing plastic isn’t, so Arora coated the 3D printed fingers in a thin layer of metallic particles so that the fingerprint scanner can read them.It’s not a foolproof method yet. Arora is still refining the technology, and they haven’t yet given the fingers back to the police to try and unlock the victim’s phone. But Arora said that in a few weeks, once he’s tested the fingers enough in the lab, he’ll hand them over. Then the police will try to use 3D printed models of a dead man’s fingers to unlock his phone.
