The spy who hacked me - Measuring the security vulnerabilities of 3-D printing

The video discusses how common smartphones can hack 3D printers by measuring leaked energy and acoustic waves. Researchers highlight the security vulnerabilities of 3D printers, which could lead to intellectual property theft, especially as 3D printing becomes a multibillion-dollar industry. The method involves using a smartphone's sensors to infer the print nozzle's location, achieving high replication accuracy. To enhance security, increasing the distance from the printer, adjusting print speeds, and using shields are suggested solutions.

Why is the ability to replicate printed objects a concern for businesses?
