A big battle is heating up over 3D-printed guns, just as tech startups prepare for a massive industry event.

In New York, a controversial developer has created a tool to bypass new safety laws on 3D printers. These printers are smart machines that can build physical objects out of plastic or metal using digital files. A recent state law requires new printers to run software that blocks gun designs. This software works by identifying a "hash," which is a unique digital fingerprint attached to each file. However, a new tool called "Hochulization" scrambles these digital fingerprints, allowing the files to bypass the block and print working weapons.

This development comes as police report a rise in homemade, untraceable firearms. In New York, police seized just 1 of these weapons in 2021, but that number jumped to 109 in 2024. Many safety groups worry about this rise in weapons. Meanwhile, tech groups and makers argue that scanning files on private printers is an invasive form of digital spying.

While some creators fight the law, others are looking to show off their inventions legally. The TechCrunch Disrupt 2026 conference will take place in San Francisco from October 13 to October 15 in 2026. Over 10,000 founders, investors, and tech leaders will gather at the event. Startups can book exhibit tables starting at $12,500 to pitch their products and find partners. These spaces are limited, and the deadline to book a spot is September 25, 2026.

Why does this matter to you? The debate over 3D-printed guns shows how difficult it is for governments to regulate digital files. At the same time, massive tech shows like the one in 2026 are where the useful everyday gadgets of tomorrow are born. Technology is moving incredibly fast, bringing both serious challenges and exciting new ideas into our lives.
