Unnecessary Inventions’ Tiny Marvel is Literally a 3D Printer That Prints Itself

Matty Benedetto built a tiny, fully functional 3D printer using an open-source Japanese design called the Fraxinus 00TW. After discovering the project online, he sourced components, printed parts in his signature colors, and assembled the complex machine despite language barriers and technical challenges. The miniature printer, powered by a portable power bank, successfully completed its first print and features a magnetic door and LCD screen - making it a completely cordless device that can print anywhere.
