Japan to mass-procure 3D-printed rocket-powered drone interceptor — Terra B1 capable of countering one-way attack platforms
Japan’s military has decided to mass-procure Terra B1 interceptor drones. These drones are fabricated using 3D printers and are based on the tried and tested A1 model from Terra Drone, which began to be deployed by Ukraine earlier this year. A demo of the Terra B1 impressed Japan’s Maritime Self-Defense Forces enough to swing the mass-procurement agreement. These interceptors are expected to capably counter notorious drone threats like the Shahed designs and anti-radar loitering munitions such as the IAI Harpy, notes 3D Printing Industry news.
The Japanese Acquisition, Technology, and Logistics Agency (ATLA) is the body that rubberstamped the deal with Terra Drone. According to a press release from the latter, the Terra B1 is being mass-produced in Japan after successfully passing trials. It was just one of a range of designs put forward by 38 separate companies. To be chosen by ALTA, the B1 had to satisfy a number of criteria such as “effective range, flight duration, flight distance, maximum and cruising speed, guidance method, number of aircraft that can be controlled simultaneously, launch and recovery methods, integration with other systems, safety measures, [and] operational track record,” says Terra Drone. The first Terra B1 interceptors are expected off the domestic production lines sometime this month.
We witnessed the clamor for cheap and effective anti-drone solutions when the conflict between the U.S. and Iran erupted earlier this year. Gulf states seen as U.S. allies or sympathizers were repeatedly targeted by airborne Iranian threats, but their anti-air missiles weren’t designed to counter such attacks. Patriot missiles, for example, are too expensive and in too short supply to match drone threats 1-to-1. It wasn’t sustainable. It didn’t take long, therefore, for battle-proven Ukrainian anti-drone tech to be bought in.
Now we see Japan proactively following the cheap-yet-effective drone interceptor route. 3D printing is another emerging tech that will be applied here to enable Japan’s Self-Defense Forces “to acquire more effective drone countermeasure equipment with greater speed.” After a successful initial deployment by the Maritime Self-Defense Force, Japan’s Air Self-Defense Force and Ground Self-Defense Force may also look at customizing Terra B1 interceptors for their needs.
This isn't the first example of important synergies between drone and 3D printing technologies. We also recently reported on drones, drone parts, and other maintenance and repair essentials being 3D printed aboard the USS Essex. This was all done inside a compact containerized factory as the ship sailed to take part in RIMPAC 2026 around Hawaii.

What I don't understand is why someone would 3d print something if they could just use injection molding and produce it for a fraction of the cost. I could see if you needed to produce something and did not need mass amounts or your were actually producing things on the battlefield where manufacturing equipment was not available.
In this case it says japan who has lots of plastic factories is going to mass produce these.
This is either a fake article or you have some really stupid people that want to feel they are being trendy and using new technology to build something so they can post video to tiktok.

3D Printing of drones casing and components allows for fast adjustments of the construction on the ever evolving FPV battle landscape without waiting for tooling and especially without spending thousands of USD for just one tooling cycle. Also, can easily imagine how they would use 3D printing for tie first few batches to refine the shape and construction, and then move to a less air-resistant mold manufacturing.
