So we’ve been cooking up some thoughts on Gen AI at @amnesty.org and I’m ecstatic to finally see it out in the world! Our 🗝️ conclusion: standalone gen AI systems, built on unlawful web scraping, constitute mass invasions of privacy by design & should be prohibited www.amnesty.org/en/latest/ne...

For the vintage and open source lovers, I've published the BearExxaV2 Prusa firmware Beta 1. ➡️ github.com/bear-lab-3d/... All changes are detailed in the README, along with the reason for each one and the code difference. Enjoy :) #3dprinting #bear #bearexxa #bearupgrade #prusa #OpenSource

DragonFruit is now officially open-source under AGPL-3.0 🎉 Build 0.1.6 is publicly available starting today while we prepare the 0.2.0 beta release. Bug reports are now handled through GitHub Issues. slicer.openresin.org

Bondtech, E3D, Prusa and the Orbiter Project have now all patented high flow nozzles. This is honestly sad, we are blocked for 15+ years with those now. But they are (all) a pain to cold pull 🫢 Patents list in the next post ⤵️ #3dprinting #nozzle #speed #Bondtech #cht #Prusa #E3D #fuge #Orbiter

A huge thank you to LDO Motors for being a Summit sponsor this year! Thanks for supporting!

I was reflecting on 3D printer motion algorithms and I remembered this image. Klipper uses trapezoidal, RRF & Marlin can do S-Curve and the new Prunt firmware can be even smoother! With input shaping we are prioritizing the wrong dev! ➡️ Read more on my blog: ekunn.com/blog/2026/05... #3dprinting

We are a mere SEVEN days out from #OHS2026 🙀 We're starting to feel antsy to get into the space and spend a weekend celebrating all things open source hardware 🥰 There's still time for you to grab your tickets (including a one day OSHWA-curious ticket for 35 euros) and join us at the Summit!

Screws look beautiful and I like to make them visible in products, but I have to admit that those hidden ones have some style too! It's based on a spring loaded mechanism and were invented by Jeff and Brandon Serle, who are cleanroom engineers. ➡️ flushfasteners.com #torx #fastener #screw #hidden

A new version of Open Cascade Technology (OCCT) 8.0 has been released. This geometric kernel forms the backbone of several projects such as #FreeCAD, #IfcOpenShell, or #KiCAD. The release announcement is here: occt3d.com/occt3d-open-... #OpenCascade #OCCT3D #OCCT #OpenSource

Thanks to @freecad.org and @prusa3d.com, my 10-year-old son designed and built a replacement part for an old, broken toy car. All in under half an hour (I helped by taking the measurements). Many thanks to the entire open-source software and hardware community. You make amazing things possible!

Absolutely AMAZING video, design, great sense of humor, very cost effective. And a CABLE running for 1000 days continuously. www.youtube.com/watch?v=GFLa...

Looking for a future where technology serves the interest of mankind instead of the other way around? OSHWA is creating a future where safe, affordable, and plentiful open source medical hardware gets built for everyone.

grabcad.com/library/logi... Got this published after a final part fit check / material validation. I'll assemble the bits fully and glue later on and get some real photos included, but for now: Its live! Logitech C920 webcam shell inspired by Leica. Multi-part single-material 3d printed assembly.

Prusa’s “Open Community License” is neither open nor for the community... a lawyer explains why blog.adafruit.com/2026/03/19/p... @josefprusa.bsky.social @prusa3d.com

We are so excited to announce the talks and workshop schedule for #OHS2026! Check out the lineup and see who is joining us from all over the world to talk open source hardware and maybe even register for one of the incredible workshops we'll have running on Day 2: 2026.oshwa.org/schedule/

What did I sidetrack myself with completely today? well, you see... My logitech C920 webcamera is UGLY AS FUCK. aka stock. Cute right? printing a test fit jig currently.

I was lucky enough to get a quick glimpse. UI is easy, smooth and speedy.

While FFF goes close source the resin industry goes open source!

I love designing and making these 3D printed organizers. Low effort, huge reward. Am I weird? CAD+3DPrint feels like a super powerñ #3dprinting

preFlight is a new open source slicer based on #PrusaSlicer but with deep rework of its internals. - Truely 64bit - GCode processing in memory - Athena algo improving over Arachne - Interlocking perimeters similar to brick layers - Deeper #RRF integration ➡️ github.com/oozebot/preF... #3dprinting

MyMiniFactory has acquired @thingiverse.bsky.social . Hopefully that makes it independent from a 3D printer brand (it was an UltiMaker product). I hope they will now add CERN-OHL V2 license, the only license that support 3D printed functional hardware. ➡️ www.myminifactory.com/blog/myminif...

And Prusa continues, so disrespectful 🤮. Flagged by so many people for their wrongdoing, yet they persist in trying to redefine open source for marketing purposes. Champions of open-source-washing! ➡️ The OCL isn't an open source license #3dprinting #opensource #prusa #disrespectful

Thank you Dave for all the great and hard work. Thank you for having trusted my work and sold many Bear frame kits. I wish you all the best for the next steps 💫 @printedsolid.bsky.social

Guess who is once again displaying their ability to hyperfocus on being a hater? It's me, I spent all evening writing my own compilation of all the reasons I think AI sucks so I can post it under genAI-made FB posts. Work-in-progress, suggestions welcome! www.skwinnicki.com/single-post/...

Medical Students Turn Recycled Plastic into 3D Printed Lab Tools 3dprintingindustry.com/news/medical...

got some more thoughts about getting more range of movement out of a single servo eye! geneva mechanism on the eyelid, to free up some rotation angles for an additional cam mechanism that rocks the eye side to side inbetween blinks! i dont have a way to add the lower eyelid yet but maybe later

The new @prusa3d.com "Open Community License" isn't just not open (in the sense that it does not meet either the OSI or @oshwassociation.bsky.social open definition), it imagines a world of IP maximalism where copyright extends well beyond its current limits: michaelweinberg.org/blog/2026/01...

We are soooo excited to announce that the tickets for the 2026 Open Hardware Summit are officially available! Snag your tickets today and maybe even get yourself an extra cool Summit tee? 👀 ticket.nodeforum.org/OHS26/

Testing a 3D printed & laser cut 35mm film onto 120 backing paper roller. Kentmere 400 shot in a Fuji GW690II. Wanted to create a pano effect using various 120 cameras. I originally DIY’d a roller using styrene sheets & PVC pipe (last photo). It worked but I wanted it improved. I worked with

It's nice to see an @adrianbowyer.bsky.social RepRap printer being used for 3D clay printing.

After many years I finally hung up the 3D Printed guitars in the table area. Looks pretty good!

All the Bambu's patents and close source hardware/software didn't stop Creality to clone the A1 ... a second time ! Instead of losing money on patents, go open source. You will build a strong community, embrace the right to repair and speed up the technology for everyone. #3dprinting #opensource

Buildlist.org is a directory of on-demand manufacturers from around the world. All of the selected manufacturers have an online quotation system that does not require you to create an account. It’s handy for finding local manufacturers! ➡️ buildlist.org www.youtube.com/watch?v=HpQ_...
