"Teleportation" Using Two 3D Printers

A Hacked 3D Printer Is Teleporting Objects Like in 'Star Trek' (+Video)

Becky Chung | January 22, 2015

Meet Scotty: a 3D printer and scanner that “teleports” objects in a way that demolishes the original and reproduces an exact replica inside a 3D printer nearby. Created by a team of researchers at the Hasso Plattner Institute, the device first slices up an object as it’s scanned—ensuring that no one can reprint the work—and then sends an encrypted copy of the 3D file to a receiving printer.

[Abstract: We present a simple self-contained appliance that allows relocating inanimate physical objects across distance. Each unit consists of an off-the-shelf 3D printer that we have extended with a 3-axis milling machine, a camera, and a micro-controller for encryption/decryption and transmission. Users place an object into the sender unit, enter the address of a receiver unit, and press the relocate button. The sender unit now digitizes the original object layer-by-layer: it shaves off material using the built-in milling machine, takes a photo using the built-in camera, encrypts the layer using the public key of the receiver, and transmits it. The receiving unit decrypts the layer in real-time and starts printing right away. Users thus see the object appear layer-by-layer on the receiver side as it disappears layer-by-layer at the sender side. Scotty is different from previous systems that copy physical objects, as its destruction and encryption mechanism guarantees that only one copy of the object exists at a time. Even though our current prototype is limited to single-material plastic objects, it allows us to address two application scenarios: (1) Scotty can help preserve the uniqueness and thus the emotional value of physical objects shared between friends. (2) Scotty can address some of the licensing issues involved in fast electronic delivery of physical goods. We explore the former in an exploratory user study with three pairs of participants.]) and (Beam me up! 3D printing 'teleporter' sends physical objects digitally just like Star Trek's transporter.
