holy fuck the open printer lives. i repeat. THE OPEN PRINTER LIVES!!!

Wow after years of asking for it, Prusa has finally added the CERN OHL v2 license to printables ... but only the stricter variant 🙄 CERN OHL v2 is the only modern open source license protecting your functional 3D prints. It has 3 variants: strong, weak and permissive. #3dprinting #prusa

Technology evolves faster than public understanding, and policy is often written in the gap between the two.

Here's the event page for the live stream Hearing on 3D Printing in California on Tuesday June 23rd: luma.com/b8sr2gj9 PLEASE share the crap out of this!

3.6.3 stable is now released: github.com/Duet3D/RepRa...

RC1 is available for RepRapFirmware 3.6.3: github.com/Duet3D/RepRa... Highlights: * Faster processing of urgent commands over USB (improves estop on DuetScreen). * DWC: Added "Run Macro" context menu option to System Files list * Various bug fixes in RRF, DSF and DWC

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.

First multicolour string print on my new @snapmaker U1 and its done a fantastic job. This is my sunburst string art printed in 3 colours. 😊 I love the mottling effect you get from certain angles.

Live in ~15! Stoked to hear more about this 3D printing pen – it's apparently 4x faster than standard, has heatsink + stand for a full roll of filament, & is repairable 🛠️✨ Got to see it at @makerfaire.bsky.social Bay Area last year – lots of cool demos! What features would you like in a 3DP pen?

New #HacksterCafe this Tuesday, ft. Tim Keller! #Hardware entrepreneurship, #3DPrinting pens, #biotech, and more... 👀 Catch it live or recorded on @hacksterio.bsky.social Tue. March 10, 10:30am Pacific / 5:30pm UTC: ▶️ www.youtube.com/watch?v=oA3W... ▶️ www.linkedin.com/events/74368... #HacksterIO

📣 RepRapFirmware 3.6.2 is released🎉: This is mainly a bug fix release but contains some minor feature enhancements. Users running Duets in standalone mode can use the files at github.com/Duet3D/RepRa.... Users running in SBC mode can update using the stable feed from the package server

For one of my clay printers, moving from 24v to 36v and upgrading the control board from the Duet2 to the Duet 3, which will then connect to the RaspberryPi. Will allow more power to reach the clay pushing motor and will make it easier to connect, add features like camera, remote monitoring, etc.

I made a tool that turns PCB designs into 3D-printable molds. you sandwich copper tape between the parts, sand the ridges, and you have a real working PCB. no etching, no chemicals. I am losing my mind castpixel.itch.io/pcb-forge

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

KiCad 10 RC1 is now available! www.kicad.org/blog/2026/02...

This dogs string art has been on my wish list for a long time and I'm so glad to have finished it. 😊 The frame prints separately so it can be printed in a single colour (Blue) or with a single colour swap (Black). Stls and 3mfs: than.gs/m/1513382

Beginning the Voron 2, serial 0 build that was donated by RCF to the Sanjay Mortimer Foundation and will be raffled off at SMRRF. Starting in about 1 hour! youtube.com/live/6ppoBoK...

Not long until the Lunar New Year festivities begin. 2026 is The Year of the Horse and this year I thought I'd combine a quilling style with my signature strings. The design prints without supports and can be printed on a single colour printer.😊 stls and 3mf: makerworld.com/en/models/22...

wikipedia turns 25 today! the last unenshittified major website! backbone of online info! triumph of humanity! powered by urge of unpaid randos to correct each other! somehow mostly reliable! "good thing wikipedia works in practice, because it sure doesn't work in theory" - old wiki adage

Looking to run a CAN-FD bus over 40m long on your Duet3D controlled system? We have updated our bootloaders to make that even easier. Who has the largest Duet3D controlled machine? docs: docs.duet3d.com/en/User_manu... bootloaders: github.com/Duet3D/Duet3...

Congratulations to @adrianbowyer.bsky.social for being the keynote speaker of #SMRRF2026 in the UK! Hope to catch the talk IRL! #3DPrinting #3DP #RepRap #RRF #maker

Vik Olliver's #RepRap Micron has done a #3Dprint with layers! The cylinder with the big blob* at the top is 500μm in diameter and 10 layers high. Details: blog.reprap.org/2025/11/fina... reprap.org/wiki/RepRapM... --- * First print... Cut Vik some slack...

If you’re a 3D printing designer you should be upset about this. Companies can slip through a bogus design patent on your model and block you from distributing or monetizing it. This would take away one of the only options for fighting that that’s even remotely affordable

SOS!! Share far and wide! The US Patent Office is working to make bad patents untouchable and that’s a problem for open source hardware! Read through EFF statement and get your comments in ASAP to help prevent this www.eff.org/deeplinks/20...

I might not be smiling but trust me im very happy

DasFilament announced a recycled PETG filament made from waste of Film production. This rPETG has the same properties of their standard PETG and is specifically designed to have unique colour changes. Available in spools and refill. ➡️ www.dasfilament.de/filament-ref... #3dprinting #dasfilament

On the way to Formnext, it's going to be an interesting show: some big announcements and launches are expected! See you there?

Kiri:Moto Release 4.4.0 is here, it's huge, it's just does one (thousand) thing(s). Mission Accomplished. End of line. Enjoy.

I'm pleased to share the schematic AND Kicad project for Pebble 2 Duo - useful if you are have fun hacking! github.com/coredevices/...

A bit more work on a new string technique. This time using it to create a glowing effect on my heart strings model. #Ilove3dprinting

Okay, for the folks who asked: here's the majority AI view, writing up the reasonable, thoughtful view on AI that the vast majority of people in tech hold, that gets overshadowed by the bluster and hype of the tycoons trying to shill their nonsense. anildash.com/2025/10/17/t... Please share!

I've always thought that the need for a fancy paper transport in printers was unnecessarily complicated and fault prone. Why not just have a roll and a guillotine? Now, here comes: www.crowdsupply.com/open-tools/o...

🎉 Mark your calendars! The 4th Annual Rocky Mountain RepRap Festival is April 18–19, 2026 at The Ranch in Loveland, CO. Two full days of 3D printers, projects, giant builds, live demos, and awesome community vibes. Admission is FREE — tickets available now 👉 rmrrf.com 🎟️

This is very cool. awesome job @properprinting.pro check out his video here: www.youtube.com/watch?v=z6So... also nice to see TeamGloomy's documentation featured

coming soon to @github.com

🎉RepRapFirmware 3.6.1 is released, announcement here: forum.duet3d.com/topic/38558/... Please read the release notes on github: github.com/Duet3D/RepRa... This contains bug fixes from 3.6.0, we recommend updating!

We're thrilled to announce the next release of KiCad: 9.0.4! www.kicad.org/blog/2025/08... Lots of bugs fixed and performance improved. We're moving on toward 10!

My friend @ivanmiranda.com took our kayak adventure a step further and printed a kayak in less than 24 hours, on a treadmill! You should definitely watch the video! youtu.be/9DpMkYDCq9Y?...

I've been looking at how infill percentage can create contrast. This vase is created in two parts the clear part is printed with 0% infill and the green with 100% infill. The clear filament completely encases the green. I really like the slightly blurry effect it creates. files link in comments

This is my Dolphin Infill Bowl, I used 30% tri-hexagon infill on the body (no walls or top and bottom layers) to create the circles for the dolphins to jump in front of, and I set the dolphin infill to 100% to make them stand out. 🐬🐬🐬 stls and 3mfs: than.gs/m/1364239

My friend @properprinting.pro made a video about printing a Kayak in one go and is even more epic than you can imagine so go watch! youtu.be/QuZW259aIn0?...
