What if the future of precision mechanics didn’t rely on massive manufacturing plants or multimillion-dollar R&D budgets, but instead emerged from a 3D printer on a hobbyist’s workbench? That’s ...

A press is a useful thing to have, whether you like destroying stuff or you simply want to properly install some bearings. [Retsetman] decided to build one from scratch, eschewing the typical ...

This 3D printed planetary gear fidget spinner is a fascinating mechanical design that seems like it could spin forever. The ...

Recognizing that 3D-printed parts inherently lack the strength of materials such as aluminum, the researchers adopted a cycloidal gear design for the gearbox inside the actuator. "The main benefit is ...

Atherton Bikes is working on a 3D-printed DH prototype that could shake up one of the first bikes they ever made – a new gearbox-driven A.200.G. There aren’t many are now quite a few more concrete ...

3D printing is a downright futuristic technology. People can use plastic filaments, resin, and other materials to create custom objects. The quality of the print is limited by a user's printer, but ...

People often contact me because they want to 3D print a replacement part. The requests have been as mundane as a stove knob or as novel as a replacement crystal for a chandelier. Typically, they are ...
