The Arcus 3D-printed rubber band gatling gun fires 48 shots per second

Sometimes 3D printing can be a reminder of humankind’s ability to triumph over our environment, as recently evidenced when the first 3D printed tool was successfully created on board the International Space Station. Other times, it can be a reminder of the wonders of modern medicine, as seen through the phenomenon of “bio-inks” and the dream of one day printing out working organs for life-saving treatment.

And then there are the times when it’s used to print out fully-automatic gatling guns capable of firing off 48 rubber bands in a matter of seconds. Is it wrong that part of us isn’t sure which of these three is our favorite application?

Created by 3D printing artisan Matthew Davis, the so-called “Arcus” is a thing of beauty, and snaps together without the need for screws or glue. Davis has made the instructions available over at Instructables, although you’ll need plenty of time and patience to get all of your 3D printed parts ready for assembly.

“I’d seen a 3D printed rubber band gun online before, which was just a basic hand-held one. I thought it was really cool, so I just set out to design my own,” Davis tells Digital Trends. “The hardest part was making it strong enough to hold the elastic bands, and getting the spinning mechanism to work was a real challenge too.”

As Davis notes, the Arcus isn’t the first 3D printed rubber band gun to show up online, but it’s definitely got some nifty features. “Unlike almost all of the other rubber band Gatling guns out there, the Arcus uses the energy from the rubber bands that it is shooting to spin the barrels,” he explains in accompanying notes. “The Arcus also features the arm mount system, meaning that to hold it you put your arm through the center and the barrels will spin around your arm. A cam system is used so that when you pull the trigger the barrels will start the rotation.”

If you’ve ever wanted to know what Final Fantasy’s Barret Wallace would print if he ever got his hands (err, hand) on a 3D printer, look no further!

Did we mention how much we love additive manufacturing?

Starlink V5 is here, and it’s lighter, smarter, and far more efficient
The next-generation satellite internet kit promises improved efficiency while maintaining high-speed connectivity.
Starlink V4 vs V5

Not every hardware upgrade needs to be about speed. With Starlink V5, SpaceX is betting that a lighter design and lower power consumption matter just as much. The company has officially introduced its next-generation Starlink V5 kit, featuring a smaller and lighter design with significantly improved power efficiency.

Frontier joins the Starlink club with high-speed in-flight internet
The carrier plans to roll out SpaceX's satellite-powered Wi-Fi across its fleet starting in 2027.

If there's one thing budget airlines aren't exactly known for, it's great onboard Wi-Fi. In Frontier Airlines' case, it hasn't offered in-flight internet at all. That's about to change. Frontier Airlines has announced a partnership with SpaceX's Starlink to bring high-speed, low-latency internet across its fleet. Installations will begin in early 2027, making Frontier the first ultra-low-cost carrier in the United States to adopt Starlink's satellite-powered connectivity.

OpenAI’s first hardware product sounds more like a companion than a speaker
The AI company is reportedly building a mobile home device that understands context and proactively helps users.

For months, rumors have suggested that OpenAI's first hardware product could be a wearable AI device, or perhaps even the beginning of its long-term smartphone ambitions. As it turns out, the company's first gadget may be something far simpler, yet arguably far more ambitious. It will help control smart-home appliances, play media, answer questions, respond to messages, and tap into the range of capabilities offered by OpenAI's ChatGPT, according to people familiar with the matter.

OpenAI's first AI device could end up being a speaker, following plenty of hype that the company is actually working on a wearable AI device and might even launch a smartphone down the road. According to a Bloomberg report, the speaker will serve as a human-like AI companion that will integrate directly with the smart home ecosystem.
