Mohammad Al Faruque of the Advanced Integrated Cyber-Physical Systems lab. "According to the fundamental laws of physics, energy is not consumed; it's converted from one form to another -- electromagnetic to kinetic, for example. Some forms of energy are translated in meaningful and useful ways; others become emissions, which may unintentionally disclose secret information," he explained, in a complicated way of saying making stuff = sound clues. Like, you could fake a chair by listening to the chipping sounds of a carpenter.

A team of researchers, headed by Mohammad Al Faruque at the University of California in Irvine, displayed the possibility of rebuilding a 3D model on the basis of the audio of the printer, while in operation. The position and movements of a 3D printer’s extruder can be determined through the sounds made by it during work.
Led by Mohammad Al Faruque, director of the Advanced Integrated Cyber-Physical Systems lab, the team found that placing a smartphone alongside the machine as it printed objects layer-by-layer enabled them to capture the acoustic signals. It says that these recordings contain information about the precise movement of the nozzle, and that information can later be used to reverse engineer the item being printed.
In research demonstrating that industrial espionage may be as simple as opening a recording app on your smartphone, a team led by Professor Mohammad Al Faruque at the University of California at Irvine has shown that it is possible to reconstruct a 3D model based solely on audio of the printer in action.
To the average visitor to the RapidTech prototyping center at University of California, Irvine, the methodical buzz of its 3-D printers would be nothing more than background noise. But to Mohammad Al Faruque, that hum is valuable information.

“In many manufacturing plants, people who work on a shift basis don’t get monitored for their smartphones, for example,” said Mohammad Al Faruque, director of UCI’s Advanced Integrated Cyber-Physical Systems Lab. “If process and product information is stolen during the prototyping phases, companies stand to incur large financial losses. There’s no way to protect these systems from such an attack today, but possibly there will be in the future.”
Can the Sound of a 3D Printer Be a Security Threat? Researchers at the University of California Think So
The research team, led by Mohammad Al Faruque, an electrical engineer, computer scientist and director of UCI's Advanced Integrated Cyber-Physical Systems Lab, discovered – almost by accident – that it is possible for an ordinary smartphone to record the very precise sounds made by a 3D printer during operation. While this may seem innocuous and even pointless, unless you’re trying to create a very avant-garde musical composition, those sounds carry very specific information about the printer’s movements. By analyzing the recording, a would-be hacker can actually reverse engineer the object being printed and then recreate it somewhere else.
One project at ARPA-E, which is a collaboration between University of California, Irvine researchers and fitness brand Under Armour, is looking to find inspiration in the way squids fluctuate the appearance of their skin, to make clothing or other devices that can heat and cool on demand.
Researchers at the University of California, Irvine have revealed a security weakness in the 3D printing process − sound waves. Scientists designed a program capable of recording and analyzing the sounds emitted by the printer's moving parts. Once decoded, the sounds − each connoting a precise movement − can be used to reverse engineer the product being printed.

The new exhibit at UC Irvine's Beall Center for Art + Technology is a place where art has come to life – literally. … "This was the first time that our lab has worked with artists," said Elliot Hui, a UCI associate professor who worked with Domnitch and Gelfand in the Hui Lab for biological microtechnology. "Art can definitely help communicate scientific concepts, but in a more beautiful and relatable way."
