ASTM, an International standards organization, is gathering the sharpest minds in hard hats and hoodies for a March 4–5 summit in Pennsylvania, where the standards body will decide whether to formalize a new committee devoted to taming AI on the factory floor. With algorithms already running machines, crunching data, and occasionally acting like opinionated supervisors, ASTM says it’s time to bring some order, common language, and guardrails to the mix. All3DP will have its eyes on developments. Register here to participate.

In a dazzling blend of fantasy fandom and cutting-edge fabrication, Olaf Diegel, who runs the additive manufacturing program at the Univ. of Auckland and has a side gig making custom guitars, just debuted this Iceman-style electric guitar called “Faerlind" (Elvish for music of the soul, of course). It's nylon 12 printed on a Voxeljet VX1000 selective laser sintering system and painted matte silver.

MakerWorld user Lorenz's parametric Any Box is one example. It lets you create and print just about any box you could wish for, making it a triumph of code and customization. There are plenty of sliders, scalers and hinge styles, giving seemingly infinite flexibility – and it features Gridfinity compatibility, too.

in a refreshingly tactile twist in an age of algorithmic everything. The BBC has opted for 3D printers and painstaking craftsmanship in its Milano Cortina 2026 Winter Olympics coverage promo. The trailer, "Trails Will Blaze", is a lovingly stop-motion world built from hundreds of individually 3D printed athletes skating, skiing, and tumbling across miniature Italian mountains. Watch the making of the promo here.

It's a simple question, but one inspired by what we're witnessing in the incredible rise of companies like ZB Designs, building multi-million dollar enterprises printing collectible toys using the same "consumer" 3D printers many of us have sitting on our desks.

It has us wondering: how many of you are monetizing your hardware and expertise? Are you leaning into the entrepreneurial side of the hobby, or do you prefer to keep your printing strictly personal?

a team of Cornell Univ. researchers plunged into the next frontier of additive manufacturing with an underwater 3D printer that could redefine maritime construction and infrastructure repair. The process includes specialized concrete "ink" and seafloor sediment as a primary ingredient that's capable of resisting washout while remaining pumpable. A final test slated for March is 3D printing complex underwater arches.

This print (the incredible Borderlands 4 "Ripper" mask – Printables) still looks great, even with the errors from so much loose debris thrown around the print volume.

Incidentally, the Snapmaker U1's five-second toolhead swap claim isn't marketing guff – for the most part it is five seconds, depending on when exactly you start the clock. It is quick.
