Collaborate Disseminate
[Steven] at the 3D Printer Academy has been working on a variety of different gear designs. He recently embarked on a series of experiments to see how fast he can spin …read more Continue reading 7000 RPM on a 3D-Printed Gearbox
If you think you’re having a bad day at work, pity the poor sysadmin at Victoria University of Wellington in Australia, who accidentally nuked the desktops of pretty much everyone …read more Continue reading Hackaday Links: March 21, 2021
Electric bicycles may require less pedalling effort than regular bikes, but … their riders still have to shift gears. Paris-based electric mobility company Valeo is out to change that, by combining a motor with an automatic gearbox.Continue ReadingCate… Continue reading Valeo combines an ebike motor and an automatic gearbox in one unit
[Brian Brocken] is at it again, building mechanisms that are as striking in their aesthetic as they are in their function. This time around, he’s extended a project we recently featured by adding a menacing 3D-printed shredder attachment. When you hear “3D-printed shredder” you think that paper is all you’ll …read more
[Petar Crnjak]’s Faze4 is a open source robotic arm with 3D printable parts, inspired in part by the design of industrial robot arms. In particular, [Petar] aimed to hide wiring and cables inside the arm as much as possible, and the results look great! Just watch it move in the …read more

Typically, when we think of 3D printed parts, we think of unique parts with complex geometries that would be hard to fabricate with other techniques. Strength is rarely the first thing that comes to mind, due to the limitations of thermoplastics and the problem of delamination between layers. However, with …read more

For about as long as hackers and makers have been using desktop 3D printers, there have been critics that say the plastic parts they produce aren’t good for much else than toys and decorative pieces. They claim that printed parts are far too fragile to be of any practical use, …read more

Scope creep is a real pain in the real world, but for projects of passion it can have some interesting consequences. [rctestflight] was playing around with 3D printed rover gearboxes, which morphed into a 3D printed tank build.
[rctestflight]’s previous autonomous rover project had problems with the cheap geared …read more

It’s often been our experience that some of the most impressive projects are the passion builds, the ones where the builder really put in their all and obsessed over every detail. Even if they don’t always have a practical application, it’s impossible to look at the final product and not …read more

Interfacing a shaft to a 3D printed gear doesn’t have to be tricky. [Tlalexander] demonstrated a solution that uses one half of a spider coupling (or jaw coupling) to create an effective modular attachment. The picture above (and this older link) shows everything you need to know: the bottom of …read more
