Musician Chris Graue has released the 3D-printable schematics and a tutorial for the adapter that allowed him to capture a photo of Jupiter using a Game Boy Camera and the Hooker Telescope, enabling anyone to replicate the setup.
The author built a tiny robot named Growbot using 3D printing, a Raspberry Pi Pico 2, servos, and a smartphone, combined with modern AI. It can see, hear, remember, move, and interact. The author shares their building journey from failure to a robot that feels alive, highlighting the transformative effect of giving AI a physical body.
New laws in California and New York aim to restrict 3D-printed ghost guns, potentially creating new surveillance measures, amid high-profile cases involving 3D-printed firearms.
The Text-CAD project achieves AI-driven automation from natural language description to STEP 3D model, slicing, and directly connecting to a Bambu printer for the entire workflow. By having the LLM generate build123d Python source code instead of directly manipulating the geometry kernel, it effectively reduces the difficulty of generating complex formats and integrates multiple hardware manufacturing-related skills.
The article announces oomwoo, an open-source, build-it-yourself robot vacuum cleaner that uses 2D LiDAR and ROS 2 for autonomous navigation, with no cloud required. It is designed for the maker community and is built in public from the start.
California's AB 2047 bill would mandate 3D printer surveillance software, threatening privacy and open source; the EFF calls for action as it moves to the state senate.
The author is physically building the classic pinball game 'Space Cadet Pinball', with key improvements such as addressing flipper overheating, insufficient pop bumper power, and creating an upper playfield and a unique ball return mechanism.
A Wired article provides guidance for parents considering buying a 3D printer for their children, sharing personal experience setting up the Elegoo Centauri Carbon for an 11-year-old.
California AB 2047 would require 3D printers sold in the state to include a government-certified detection algorithm, effectively banning them from schools, libraries, and small businesses. The 3D printing industry strongly opposes the bill, arguing the required technology is impossible and would violate the First Amendment.
MIT researchers reinvented the zipper using a three-sided fastener inspired by a 40-year-old patent, allowing rapid transformation from flexible to rigid for applications like tents and casts.
Optocam Zero is a compact DIY digital camera based on Raspberry Pi Zero, using off-the-shelf components and 3D-printed parts. It features autofocus, filters, GIF recording, and easy image transfer via hotspot.
Dany Bittel recounts printing a 3D Gaussian splat of an insect using Crysta.AI's printing service, discussing the technical adjustments needed for physical output and the potential of this technology for preserving 3D captures.
PrintGuard 2.0 is a major rewrite of a few-shot FDM fault detector using a ShuffleNetV2 backbone and prototypical network, now with a single Python engine that runs unmodified on both CPython and Pyodide in the browser via a platform abstraction layer, enabling per-printer sensitivity tuning and fair inference scheduling.
A developer built a 3D printed robot with expressive eyes, object tracking, and support for ChatGPT, Qwen, and offline AI models, then released all STL files, code, and hardware designs for free, highlighting the shrinking gap between idea and working product.
The author successfully repaired the Revo hubless bike, known as 'the world's worst e-bike,' through reverse engineering, cracking the Bluetooth password, and creating a custom screen, restoring all its functions and adding new features.
A Chinese girl created a mesmerizing gear-driven 3D-printed Medusa model.
This article describes the author's project of bringing the pinball table from the classic Windows game "Space Cadet Pinball" to life, building a real mechanical pinball machine from scratch using 3D printing, microcontrollers, and homemade mechanisms. It details the design and iteration of rebound buffers, drop targets, slingshots, and other features.
Prusa released an open-source color mixing model called ColorMix for PrusaSlicer and EasyPrint, enabling multi-material printers to print with dozens of color tones by alternating thin layers of different filaments.
Josef Prusa accuses BambuStudio of violating the AGPL license of PrusaSlicer, and highlights Chinese laws that may force Chinese companies to comply with government data requests, raising security concerns in 3D printing.
A developer is using AI-assisted CAD (Claude Code) to design a custom wrist-mounted diving computer, compressing what was a multi-week design process into a weekend project. The final device will be 3D-printed and run the Bühlmann ZHL-16C decompression algorithm.
