This coffee-based 3D printing filament emits a pleasant smell while you print with it

At this point, it’s no secret that 3D printing technology is progressing in leaps and bounds. But what you might not realize is that while the machines themselves have steadily gotten more advanced, the filaments they print with have also been experiencing a revolution.

It’s not just ABS and PLA anymore. Nowadays we’ve got 3D printing filament made from dozens of different materials. Wood, bronze, nylon, carbon fiber, water-soluble plastic, flexible rubber — you name it and there’s probably a filament made of it. And the list just keeps on expanding.

The latest addition to the ever-growing category comes from the filament wizards at 3Dom. The company, which specializes in eco-friendly printing materials, has just released a new filament that’s made from the waste byproducts of coffee — dubbed Wound Up.

It might sound like a gimmick at first, but filament derived from old coffee grounds actually boasts a number of advantages over traditional PLA. In addition to the fact that it’s made from recycled materials and is therefore more environmentally friendly, 3Dom’s coffee-based PLA also gives off a pleasant smell when it heats up. According to the company, the filament emits the aroma of “a sweet, syrupy latte” as it comes out of the extruder.

As if that wasn’t awesome enough, Wound Up also gives printed objects a unique finish. The filament’s inconsistent color and darkness result in a natural grain on whatever you’re printing. You also don’t need a special printer to use the stuff. It can be printed in any machine capable of printing with PLA, using standard PLA settings — which means practically every FDM printer known to man can work with it.

And the best part? You don’t have to wait around to get your hands on it. Wound Up is available right now, and can be snagged for 49 bucks per spool on 3Dom’s website. That’s a tiny bit more expensive than regular PLA, but just think of how much money you’ll save on scented candles!

AI bots are now trying to sabotage public health policies, like banning disposable vapes
Thousands of AI bots voted in a public health poll to block sales restriction on disposable vapes. It's like Big Tobacco is back from the dead.

In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails. 

Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.

A tiny smartphone gadget can detect some of the nastiest chemicals in your water
Scientists built a tiny smartphone gadget that can spot toxic 'forever chemicals'
Smartphone-connected drinking water safety sensor Featured

What if checking your drinking water for dangerous chemicals were as simple as plugging a tiny gadget into your smartphone? Researchers in Japan have developed a compact sensor that could make that possible, potentially bringing sophisticated water contamination testing out of expensive laboratories and into people's hands.

Scientists at the Okinawa Institute of Science and Technology (OIST) have created a portable device capable of detecting extremely low concentrations of PFAS, commonly known as "forever chemicals." The findings were published in the journal Biosensors and Bioelectronics, which demonstrate how an inexpensive sensor and a smartphone could make identifying potentially harmful chemicals in water a lot easier.
