Innovative startup turns old fishing nets into new 3D-printer materials

Add as a preferred source on Google

Whether you’re looking to save the planet or just cool new 3D printing materials, a U.K. startup called Fishy Filaments has something to offer. Started by materials scientist and geologist Ian Falconer, the project’s goal is to save discarded fishing nets from clogging up landfill sites by, instead, turning them into tomorrow’s 3D-printer filaments.

“In simple terms, I’m trying to set up a local plastics recycling company that transforms used fishing nets into a high-value, high-quality product for use in relatively low-cost fused filament 3D printers,” Falconer told Digital Trends.

There are multiple benefits to the quest, Falconer explained. As mentioned, taking used fishing nets and providing a clean, self-financing on-shore waste disposal system makes a lot of sense. It also potentially provides a local source of usable plastics that aren’t directly dependent on volatile oil prices or hazardous locations.

In 2016, Fishy Filaments demonstrated that its recycled fishing nets could be used by a commercially available, low-cost 3D printer. Now Falconer has launched a crowdfunding campaign with the aim of raising 5,000 pounds ($6,178) to take the project to the next level. While only a modest amount, the money raised will go toward a commercial feasibility study, requiring a new extruder for melting the netting strands together, along with a reel for collecting them.

So will we all be printing with Fishy Filaments a few years from now?

“The local-scale business model will limit its scalability to the amount of plastics available locally,” Falconer, who lives in Cornwall, on the southern coast of England, continued. “The potential, especially in the fisheries sector, is more for a regional or franchise-like model. Each fishery has a distinctive culture and set of target species defined by natural fish distribution. The practice in that fishery extends to net types and gear usage. That means different polymers used differently and in different volumes. From a recycling perspective, it means that technical processes and products developed to work in Cornwall might not work in, for example, Peterhead. Logically then Fishy Filaments Cornwall might spawn Fishy Filaments Peterhead, but their product lines would probably be different, which is no bad thing for a commercial concern.”

In other words, you’re probably not looking at the next unified mass-market filament, but it’s definitely a demonstration of how local thinking — combined with the latest in emerging technology — can produce some nifty results. Given that every area produces its own recyclable waste, all you need is some smart thinking (and a few 3D printers) to put it to good use.

If you’re interested, you can contribute to the crowdfunding campaign here. You may even get a spool or two of recycled fishing net filament out of it!

Yet another study says AI is bad for elections, and the rabbit hole gets worse
AI may be an election bomb waiting for someone to light the fuse
Voters cast their ballots on Election Day

Another election, another study has concluded that asking an AI chatbot for political guidance is a spectacularly bad idea. Research conducted during Hungary’s 2026 parliamentary election found that ChatGPT and Google Gemini offered not just inaccurate but also inconsistent and unreliable voting advice. The chatbots misclassified voter profiles, overlooked relevant parties, recommended parties absent from the ballot, and sometimes produced materially different answers when given the same information repeatedly.

Samsung’s humanoid robot ambitions are real, but factories come first
Samsung’s new robotics division has humanoids in its sights, although its immediate business is far more practical factory automation
Robot Touch Human Finger

Samsung wants a place in the humanoid race, but its new robotics push begins with machines built for factories rather than homes.

The CEO-led RX robotics division will initially focus on manufacturing robots. Samsung has separately identified humanoids as a priority, although it hasn’t announced a commercial model or explained where one fits into the division’s immediate plans.

The future of AI may depend on this one behind-the-scenes change
Running Claude on Android.

Whenever a new AI model arrives, it's easy to get caught up in the bells and whistles. We talk about how much smarter it is, how quickly it answers questions, or how realistic its images have become. But here's the thing: none of that matters much if the AI can't reliably work with the apps and services people use every day.

That's why an upcoming update to the Model Context Protocol (MCP) caught my attention. It isn't a new chatbot or a fancy AI model. In fact, most people will never even know it's happening. But it could quietly make the AI ecosystem a lot healthier. If you've never heard of MCP before, don't worry. Think of it as a shared language that lets AI assistants safely talk to apps like Gmail, Slack, calendars, databases, and countless other services. Instead of every company inventing its own way to make those connections, MCP gives everyone a common rulebook.
