We thought that 3D printing a gun was already disturbing. Now someone has gone one step further with a homemade guided “missile”

Talking about 3D printing is no longer just talking about prototypes or industrial environments. In recent years, this technology has been established as a tool available to enthusiasts and creators who can design and manufacture complex objects from home with relative ease. That accessibility has expanded the possibilities of use, but has also opened debates about its limits, especially when it intersects with weapons development. The precedents of 3D printed guns They have been on the table for some time, and now a new project once again pushes that debate into even more delicate terrain.

The disturbing jump. What has now put the focus on this issue is a video of just five minutes in which the amateur Alisher Khojayev shows a prototype that is reminiscent, at least in its approach, of portable anti-aircraft missile systems. The project includes a launcher, a projectile and several electronic systems designed to assist in guidance.

What does it teach. In practical terms, what Khojayev shows is a set divided into three parts that the creator presents as a coordinated system. The launcher acts as the base of the system, the projectile concentrates a good part of the 3D printed components, and an additional node with a camera can be incorporated to reinforce tracking.

How the system is laid out. The architecture proposed by the project is based on linking several devices through a wireless network that coordinates the flow of data. The first step is to connect the launcher with a control computer via WiFi, which analyzes the information received and calculates the trajectory. In a second phase, the projectile becomes part of that network and receives instructions to adjust its orientation using moving surfaces. The system combines ESP32 microcontrollers with sensors such as GPS, barometer, compass and an inertial measurement unit to estimate variables such as speed and position.

The cost data. The project is not only presented as a technical demonstration, but also as a low-cost exercise. According to the creator, the entire system can be assembled for about $96 from commercial components and 3D printed parts. That, of course, doesn’t mean that anyone can make something similar at home, not least because such a development would probably be illegal in many parts of the world. But it does leave a broader reading: 3D printing is reducing barriers and costs in a growing variety of projects.
