3d-printing

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.

Hugging Face released LeRobot Humanoid, an open-source, low-cost ($2,500) 3D-printed humanoid robot platform, including hardware, simulation, and control tools for robot learning research.

LeRobot Humanoid is an open, low-cost bipedal robot platform for robot learning, including hardware, runtime, identification tools, and training environments, built from 3D-printed and off-the-shelf parts for about $2,500.

The article details how Bambu Lab's attempt to suppress open-source code for remote control of its printers sparked a backlash from the open-source community, with figures like Louis Rossmann and GamersNexus offering legal support and forking the code.

Colossal Biosciences announced a 3D-printed artificial eggshell to grow chicken embryos, aiming to revive extinct birds like the dodo and moa, though experts note prior similar work.

Discusses the housing crisis in Canada and the US, questioning when AI and robotics will provide widespread solutions such as 3D-printed homes and prefabricated construction, despite local regulatory hurdles.

Software Freedom Conservancy announces a compliance investigation into Bambu Lab's violations of the AGPLv3 license, confirming that Bambu's 3D printer slicer fails to provide complete corresponding source code for its proprietary networking library.

Una red de personas con impresoras 3D fabrica sillas de movilidad para niños de 1 a 8 años, pero en España hay pocos participantes y muchos niños que las necesitan.

An open-source developer argues that Bambu Studio's integration of the closed-source bambu_networking plugin violates the AGPL v3 license, and responds to Bambu Lab's public accusations.
