Today, we are releasing the full CAD files for the CORE One and CORE One L frames.

There seems to be a custom licence.

The Restriction: You cannot commercially exploit the design files (selling the product or remixes) without a separate agreement.

The Protection: It includes an explicit patent license grant, protection against AI data mining, and a codified Right-to-Repair.

Most of the linked article is about the licence.

There's been a lot of talk about Prusa turning evil. Maybe it's a good step back.

I think that it's a reasonable license for them to protect their business while continuing to provide full access to the community. The single user would still be able to modify or even build their own clone, but a private company would not be able to just sell a copy.

In an ideal world where money did not exist this would be detrimental to innovation, but in the real world Prusa needs to make money to stay in business. And considering their competitors, I would much prefer them to stay in the business and as much ahead of the competition as possible.

They are already behind the competition and have been for some time

Yet a lot of those businesses lean on the work of prusa.
Friend of mine always used creality their shitty slicer clone for his ender 3 v2, then got a bambu and was amazed by all the settings and options, different supports etc etc.
Told him he should have switched to prusaslicer ages ago, which bambu's slicer is based on and the sole reason its open source.
(Also, orca slicer > bambu studio)

Prusa has been fighting the enshitification of 3d printing so badly, they are going under while other companies are standing on their shoulders and pushing them under ><

Yes, a lot of the groundwork was done by prusa, and yes a lot of companies are standing on their shoulders. Prusa 100% deserves a lot of credit for enabling what 3D printing has become today, no doubt about that...but they haven't really been innovative or at the front of 3D printing for a while, they stagnated and have been overtaken as a consequence.

Edit: most of the cheap Chinese manufacturers are ahead because they lean massively in to klipper and rely on the community there.

Prusa has innovated. Not on their printers, agreed there, but in the slicer they have. And imo, those brands that are standing on prusa's shoulders should pay them for that work but afaik, and do correct me if im wrong, they dont. Bambu does nothing back for prusa, the opposite even. They are killing the shoulders they are standing on and barely do something for communities. Creality was also that bad until they were forced to by a chinese maker that is now at large.
Then other companies came and took creality's crown by using the opened designs.

I joined the 3d printing scene at the wrong time as i saw giants like prusa slowly fall and be replaced with shit heads like bambu

[-] ExcessShiv@lemmy.dbzer0.com 0 points 3 months ago

My point is that any innovation by prusa, slicer or printer, is pretty much past tense.

[-] mechanismatic@lemmy.world 1 points 3 months ago

Granted it's from a partnership, but the INDX extruder seems to be on the cusp, so the idea that Prusa is behind seems odd. And the fact that they're more open and consumer friendly than Bambu is great. There are a lot of affordable printers that have benefited from Prusa's development while Prusa is still dropping new developments, seemingly at a greater rate now than previously.

[-] ExcessShiv@lemmy.dbzer0.com 0 points 3 months ago

INDX is done by a completely different company, you cannot credit their work to prusa at all.

[-] mechanismatic@lemmy.world 1 points 3 months ago

It's a partnership and the INDX isn't a separate printer, just a new extruder, so it's not like Prusa has no involvement. I would say "completely" is inaccurate here. If it were solely the effort of INDX, they wouldn't need to partner with Prusa. There are other third parties that release mods for printers that aren't collaborations with the original manufacturer.

If Prusa hired the INDX engineers from BondTech instead of partnering, would you still consider it completely separate? A company is just composed of current employees. At what point is it Theseus' ship of development?

And that's not even considering the CORE One, the recent CORE One+ update, the CORE One L announcement, the OpenPrintTag, et al. They've been announcing more new stuff in the last year at a faster rate than previous years.

How is Prusa turning „evil“? And please keep in mind other 3D printing companies exist that are potentially extremely harmful for end consumers already because of their ecosystem.

[-] papalonian@lemmy.world -1 points 3 months ago

I'm far from the most knowledgeable on the subject, but I remember hearing something about one of their prospective printers not being listed as open source, and that they partnered with some Israeli company.

[-] prenatal_confusion@feddit.org 1 points 3 months ago

Please please please don't make the mistake of assuming that the current government of Israel is the same as the people living in Israel or are running companies there.

It's like accusing everybody that speaks Russian of genocide or thinking that all us Americans endorse ICE. All Asians started COVID and so in.

Differentiate

[-] papalonian@lemmy.world 1 points 3 months ago

Like I said, I'm not the most knowledgeable person on the subject, so I don't know if there was more to the outrage than just "it's an Israeli company". I'm not currently in the market for a prusa printer, so I'm not particularly invested in their politics, just speaking on things that I have seen in this community

[-] Bluewing@lemmy.world 1 points 3 months ago

Just how many angels can dance on the head of a pin? Or more importantly, how many demons can skate on a snowflake? How much purity is needed?

The best licences protect everyone. This one seems to do a pretty good job of protecting both Prusa and the consumer. Is it perfect? No. But it's far better then Prusa getting raped and pillaged into nothing. And it goes a very, very, very long to protect consumers access to parts and design specifications.

The commercial restrictions mean this license does not meet the open source hardware definition, one that was signed by a RepRap developer called Josef Pruša. https://freedomdefined.org/OSHW

[-] prenatal_confusion@feddit.org 1 points 3 months ago

Like Open source software licenses changed over time to include some mechanisms to protect the software against exploitation. E.g. large scale use and no kickback in support for paying additional developers. I feel that this is happening here and the no compromise idealistic manifest from the beginning needs amending.

[-] RobotToaster@mander.xyz 0 points 3 months ago* (last edited 3 months ago)

Those aren't open source licenses, they violate point six of the open source definition https://opensource.org/osd

[-] prenatal_confusion@feddit.org 1 points 3 months ago

Then call them something else. They are here for a reason and so is the ocl.

[-] RobotToaster@mander.xyz 0 points 3 months ago

They're called "source available", the issue is Prusa calling something open source that isn't open source.

[-] protogen420@lemmy.blahaj.zone 1 points 3 months ago

I feel like a term for open source with the exception of no commerical allowance is needed

[-] 1100101000110@lemmy.world 1 points 3 months ago

Could this be a response to Bambu Lab?
