Modular Violin Takes A Bow

Posted on by

They say the only difference between a violin and a fiddle is the way you play it. If that’s so, this modular violin will need a new name, since it can be broken apart and changed in ways that make it sound completely different, all within a few minutes.

The fiddle is the work of [David Perry] and has 3D printed body, neck, pegbox, and bridge. While it might seem useful on the surface as a way to get less expensive instruments out in the world where virtually anyone has access to them, the real interesting qualities are shown when …read more

Knock Your 3D Printer Down To 2D

Posted on by

Hackers love 3D printers. In fact, they might love them a little too much. We hope know we aren’t be the only ones who couldn’t turn down a good deal on an overseas printer (or two). But when you’re not pumping out plastic boats and other PLA dust collectors, what are you supposed to do with them?

Well if you’re like [Uri Shaked] you could hand them a pen and tell them to get writing. The holidays are coming up quick, and somebody’s gotta sign all these cards. In his detailed write-up, he shows how he was able to add …read more

3D Printed Sneakers Are Now A Thing

Posted on by

Shoes may seem simple at face value, but are actually rather complex. To create a comfortable shoe that can handle a full day of wear without causing blisters, as well as deal with the stresses of running and jumping and so on, is quite difficult. Is it possible to create a shoe that can handle all that, using a 3D printer?

[RCLifeOn] discovered these sneakers by [Recreus] on Thingiverse, and decided to have a go printing them at home. While [Recreus] recommend printing the shoes in their Filaflex material, for this build, one shoe was printed in thermoplastic polyurethane, the …read more

Maker Faire NY: Cocoa Press Chocolate Printer

Posted on by

If you haven’t figured it out by now, the hype over desktop filament printers is pretty much over. But that doesn’t mean there aren’t new avenues worth exploring that use the basic FDM printer technology. If anything, the low cost and high availability of 3D printer parts and kits makes it easier to branch off into new territory. For example, experimenting with other materials which lend themselves to being “printed” layer by layer like a thermoplastic. Materials such as cement, clay, or even chocolate.

[Evan Weinstein] brought his Cocoa Press printer to the 2018 World Maker Faire in New York, …read more

Maker Faire NY: Infinite Autonomous 3D Printing

Posted on by

Although it’s not an idea that has yet trickled down to $200 printers drop-shipped from China, one of the most innovative ideas in the 3D printing world in the last few years is putting plastic down on a conveyor belt. Yes, MakerBot was doing it back in 2010, but we’re not going to talk about that. Printing on a conveyor belt instead of a static bed allows you to easily print multiples of an object autonomously, without any human interaction. If you’re really clever, you could rotate the hot end 45° and build a piece of plastic that is infinitely …read more

Thousands of 3D Printers Exposed to Attacks

Posted on by

Security researchers warn that there are almost 4,000 3D printers whose web-based management interfaces are exposed to the internet without authentication. The management interfaces allow attackers to download G-code project files, which define the 3D… Continue reading Thousands of 3D Printers Exposed to Attacks→

Scratch-Built 3D-Printer Goes Back to the Roots of the Hobby

Posted on by

It’s so easy and so cheap to order things like CNC routers and 3D-printers off the shelf that we can be forgiven for forgetting what was once involved in owning machines such as these. It used to be that you had no choice but to build your machine from the ground up. While that’s less true today, it’s still the case if you want to push the limits of what’s commercially available, and this huge scratch-built 3D-printer is a good example of that.

It’s not exactly a fresh build – [Thomas Workshop] posted this last year – but it escaped …read more

3D Printer Guardian Watches for Worst-case Failures

Posted on by

Some devices have one job to do, but that job can have many facets. To [jmcservv], an example of this is the job of protecting against worst-case failures in a 3D printer, and it led him to develop the 3D Printer Watchdog Guardian. When it comes to fire, secondary protection is the name of the game because it’s one thing to detect thermal runaway and turn off a heater, but what if that isn’t enough? The MOSFET controlling the heater could have failed closed and can no longer be turned off in a normal sense. In such cases, some kind …read more

Putting More Tech Into More Hands: The Robin Hoods of Hackaday Prize

Posted on by

Many different projects started with the same thought: “That’s really expensive… I wonder if I could build my own for less.” Success is rewarded with satisfaction on top of the money saved, but true hacker heroes share their work so that others can build their own as well. We are happy to recognize such generosity with the Hackaday Prize [Robinhood] achievement.

Achievements are a new addition to our Hackaday Prize, running in parallel with our existing judging and rewards process. Achievements are a way for us to shower recognition and fame upon creators who demonstrate what we appreciate from our …read more
