Nice! That’s not bad at all. Any trouble with print consistency or maintenance?

Nice. Larger bed size definitely fits my needs better.

Check out reAM250 powder bed fusion 3d printer

Looks like a step towards true industrial metal printing.

“Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design. The hardware’s source, the design from which it is made, is available in the preferred format for making modifications to it.” - https://oshwa.org/resources/open-source-hardware-definition/

So I make a pile of sticks, that pile of sticks is open source? No.

You are confusing using open source tools with being an open source project. Using open source tools is great as a user, but it does not make what you do with them open source, whether it makes the activity legal or not. Publishing the design of the tool to be replicable by others is what made that tool open source in the first place for you to use.

It is the difference between “I built this house out of bricks woth my open-source backhoe” and “I built this house out of bricks this way, and here is how you can do it the same way”. Neither one is illegal, but one is an open source project and the other is just permissible under the law.

Public Domain =/= Open Source either.

Thanks for sharing your experience. I do hesitate on projects like this for this rreason, it’s always the small stuff that seems to get in the way of a streamlined experience. That said, I feel like building one rather than buying off the shelf would give me a lot more know-how about how to troubleshoot and maintain the system I am using, plus I prefer to support Open Source initiatives when I can over walled gardens.

You know, as an aside, this kind of part kitting is one of those things that I think LLMs might actually make a meaningful change in very shortly. No one wants to individually order all the parts on a BOM right now because it is a bunch of labor, but do it once with an activity log of your purchasing behavior and the sites/vendors used and there is no reason it cant be fully automated and shareable as simply as the BOM itself. Add in a function to check pricing and inventory against other related vendors and it could get quite good.

How can hardware be open without build documentation? Unlike software which is infinitely replicable and open unless obfuscate, hardware is private by default as the method of construction is effectively the “source code” and can not generally be derived without direct access to the hardware in question and disassembly. Dissassembly without reassembly instructions can only derive vocational information, and reverse engineering is required to translate that to assembly instructions which themselves are likely to differ from the prior engineer’s method.

Hardware is only open source if its assembly documentation is made openly available.

“Open source hardware is hardware whose design is made publicly available.” is the first sentence of the link you provided. Viable Hardware Design includes assembly, because as any hardware engineers will tell you a schematic is only valuable if it has been proven possible. Schematics themselves are documentation, design of hardware is documenting hardware otherwise you are crafting not designing.

End rant, lol.

Excellent!

Nice! Great list, do you run any of them?

Nice, there was one other mention but good to see a full vouch for Voron, definitely the kind of projected I had in mind.

If he didnt publish a build guide it’s not open source hardware.
