Best STEAM education tool I know! πŸŽ„ 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’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.

China already treats 3D printers as strategic and we should too!

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 β€” 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. πŸ‘€ Stay tuned.

... by itself (inventory systems for example), it makes sense to announce right away instead of silent switch and big "we've been shipping these for months, surprise!" later. Classic chicken and egg problem 😬 ...

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! πŸ’‘

#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.

Prusa Core One L boxes in the factory.

Prusa Core One L boxes in the factory.

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 πŸ›¬ Happy printing!

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