This is the internal design of the future E3D high speed nozzles, called the FUGE! Unlike the CHT ones, there is no more channelling. Instead, the filament core is warmed up by altering its path while maintaining the same surface area throughout. This is an application of the E3D patent from 2020.

You will obviously notice the close resemblance to Bambu printers. It seems that the enormous quantity of recent BambuLab patents doesn't affect the competition that much. It's not surprising as the patent system in China seems to have different goals; let's see how it evolves in the coming months.
AnyCubic has achieved an impressive level of integration with its Kobra X 3D printer. It doesn't require an AMS-like system; it can handle everything in the toolhead! It also features an automatic filament gears tensioning system. I want to see a teardown!

The resin 3D printing industry now benefits from a new and advanced open source UI called Orion. Developed by @openresin.org, it's currently running as a beta testing on the Athena II printer from Concept3D Systems Inc.

PERA would drag us back to the era of the worst junk software patents. www.eff.org/deeplinks/2...
PERA Remains a Serious Threat to Efforts Against Bad Patents
PERA would overturn long-standing court decisions that have helped keep some of the most problematic patents in check. This includes the Supreme Court’s Alice v. CLS Bank decision, which bars patents

I'm helping rep @oshwassociation.bsky.social at the Entomological Society meeting to tell scientists about how to #opensource their tools!

Any tools, big or small, as sophisticated as some kind of genetic engineering rig, or as simple as a board for bugs to crawl under can be opened! #entsoc25

We eat, sleep, and breathe #3DPrinting over here at E3D, so of course the soundtrack to our lives also has to be FDM related 🎵

We’ve made a start on a 3D Printing playlist ... comment your song suggestions down below and we’ll get them added in!

Happy listening! 🎧 https://bit.ly/49dCREE

After Prusa moving out of open source hardware, they are now taking two extra steps forward:

1. The Core One L will not be provided as a kit anymore
2. It is very probable that they will adopt patents with the INDX

Great to see that the CERN OHL V2 #opensource hardware license is the most used one in 2024 and 2025 so far.

If you're working on open source functional/mechanical #3dprinting projects, it is the license you should use. Others may not protect your work as they are not made for functional hardware.
