Best STEAM education tool I know! 🎄 MK4S kit - the build itself is the first lesson. Mechanics, electronics, problem-solving. Then it prints basically anything for years. Free worldwide shipping, tariffs prepaid at checkout ⤵️

China already treats 3D printers as strategic and we should too! Read my op-ed: www.lbc.co.uk/article/chin...

China’s grip on 3D printing is becoming a military security threat for the British | LBC
When we talk about national security, most people think of hackers, data leaks, or hostile cyberattacks. Few would imagine that something as ordinary as a 3D printer could pose a similar danger.

I was asked to share my views on 3D printing as strategic industry for @LBC. Today, 3D printers are no longer just hobby tools - they build prototypes, medical devices, drones... The key question is: can we afford to use unsecure tech? ⤵️

We’re here at #formnext whole week — stop by to check out the products we launched last month, get hands-on with our latest tech, and meet the people who built it. And yes… we’re also preparing something new. 👀 Stay tuned. #3Dprinting #AdditiveManufacturing #PrusaResearch

#PrusaDay25 FAQ: 2 - Why are you shipping OpenPrintTags without readers on the printers 🤦‍♂️? A: We've been tagging Prusament spools since the very beginning for internal use with UHF tags💡With the new spools we switched to OpenPrintTags. Because these tags are useful outside of printers ...

I am sorry about that, but it got extra input shaping making it super fast instead. Hope this makes it up for you. Both were not feasible.

Hey, thanks for taking the time to share your concerns! I really appreciate direct feedback like this. I'd genuinely love to dig into the specifics with you so we can have a productive conversation. Do you have some specific reasons we are falling behind? And the unfulfied promisses with Mini+?

Prusa Day 2025 was huge 🤯 There was a ton of new things so let me start a little FAQ for all your 3D questions! 💡 #PrusaDay25 FAQ: 1 - Why is there no upgrade kit from Core One to Core One L? A: Simple, because the Core One L is extending our lineup with a new size. C1 will have it's own upgrades.

Josef Prusa @josefprusa.bsky.social · 10/11/2025
CORE One L shipping now! 🧡 Unpack, pick your language, and you're printing. Factory pre-calibrated (Phase Stepping + Input Shaper). Even LCD mounting is a breeze now. Our best packaging ever - I'm genuinely proud of this box. And the graphics 😍 First will start arriving today 🛬 Happy printing!

🤔 Should we make Core One frame parts set without the paint aimed for easy modding? I think some colorways could be very pretty

Prusa EasyPrint: Slice on Your Phone, Tablet, or Laptop! (Early Access) - Original Prusa 3D Printers
Ever since I built my very first 3D printer, I’ve been driven by the idea of making 3D printing more accessible. Part of that was dreaming about a slicer that runs on any device and is so seamless that anyone can...

Once we are out of the early access, you will see other printers being added - such as Voron 🧡 8/9

We wanted to provide the ease of printing for everyone, not just our machines. Slicing is the only way! Sharing G-codes is just creating another walled garden, we tried it in the early days of @printablescom and knew that we can do better. 7/9

This will be a godsend for people who have only work laptops in the domain and cannot install applications without the admin approval. 6/9

Josef Prusa @josefprusa.bsky.social · 25/02/2025
Much easier slicing on Chromebook. No need to install specialized software or wrestle with system restrictions. This is especially nice for students and teachers who can simply open a tab and prepare their 3D models. 5/9

Josef Prusa @josefprusa.bsky.social · 25/02/2025
Completely new workflow for advanced tablet users who sculpt or 3D model on the tablet. You can now slice it directly on your tablet and send it to the printer without convoluted file transfer, etc... 4/9

Josef Prusa @josefprusa.bsky.social · 25/02/2025
Easier 3D printing for beginners. Slicing can feel overwhelming if you are new to 3D printing, but Prusa EasyPrint removes that barrier 👍 No complicated installation, settings, no profile set-up. Just click, slice and print 🚀 3/9

Over the next few months after Elon realizes he did bet on wrong horse it will be scorched earth is my bet. Not that it was great before but some communities were really nice.
