PAROL6: 3D-printed desktop robotic arm (source-robotics.github.io)
PAROL6 is a high-performance 3D-printed desktop robotic arm. The design approach of PAROL6 was to be similar to industrial robots in terms of mechanical design, control software, and usability. Control software, GUI, and robots STL files are open-source. You can build your own PAROL6 robot by following the instructions located in Github respository.

Show HN: OpenSCAD configurable calendar 3D model (chrastecky.dev)
I love creating configurable generic models using OpenSCAD, and this is the most complex one I've created to date—an easy-to-configure calendar using some clever algorithms to render correctly.

LMD: A new, less wasteful metal 3D printing technique (core77.com)
Metal 3D printing is currently dominated by powder-based techniques like SLM (Selective Laser Melting). These processes yield incredibly precise parts, but the build times are slow. Furthermore, dealing with the powder increases manufacturing complexity: Whenever the powder is transported, loaded into the machine, or cleaned up afterwards, rigorous steps must be followed to prevent the loose spread of powder.

Show HN: Design/build of some parametric speaker cabinets with OpenSCAD (calbryant.uk)
This post documents a saga of speaker design dating back to 2019. Since then, I’ve been gradually working on a CAD model for a new set of what started as (yet another) subwoofer, but became some compact 2-way office ribbon speakers.

3D-printed "ghost gun" ring comes to my community–and leaves a man dead (arstechnica.com)
It's a truism at this point to say that Americans own a lot of guns. Case in point: This week, a fire chief in rural Alabama stopped to help a driver who had just hit a deer. The two men walked up the driveway of a nearby home. For reasons that remain unclear, a man came out of the house with a gun and started shooting.

Show HN: 3D printing giant things with a Python jigsaw generator (calbryant.uk)
I really like the idea of a fully automated pipeline1 when I build anything – it’s highly satisfying to see a machine do all the work for you. Combine this with parametric design, and it makes iteration and customisation a breeze. My flagship example is my recent speaker project.

Bambu Lab pushes a "control system" for 3D printers, and boy, did it not go well (arstechnica.com)
Bambu Lab, a major maker of 3D printers for home users and commercial "farms," is pushing an update to its devices that it claims will improve security while still offering third-party tools "authorized" access. Some in the user community—and 3D printing advocates broadly—are pushing back, suggesting the firm has other, more controlling motives.
