Yeah, I'm curious how Prusa will go about enforcing this license and how it will play out for them overall, especially more that they're pursuing patents.
Voron isn't quite the only open printer. There are some others that are loosely based on/related to Voron, like Micron and Salad Fork, plus Ratrig which has a very different lineage.
Huh, it very well might. 90Sr is a beta emitter, which should excite phosphorescent materials nicely. Even better, it decays into Yttrium 90, and Yttrium Aluminate is also phosphorescent (it's also the YA in YAG lasers). Anyone have some spare 90Sr we can test this with?
Well, with a 28.8 years half life it should glow a while. BUT, the largest license exempt quantity one can get iirc is 0.1 uCi. Plus it’s a fission product so good luck making it yourself. :) I don’t recommend the radioactive Boy Scout approach.
My custom built 3D printers are somehow less annoying to use than my HP inkjet and laser printer, and I was already planning on getting a different brand when they died. This seems like HP is suddenly trying to play hard to get when they're already hard to want.
I wonder why, with the ubiquity of DIY open source 3d printers, I can't seem to find a single open source design for a document printer that takes standard toner cartridges. Youd think something this simple would find the interest of some hobbyist out there.
I hadn't even thought of that, but, my X1 carbon (which I've had for only a month or so) is definitely far less fiddly than my HP printer for printing anything besides basic stuff.
Much of the time the size of your army was determined by the number of able bodied men that lived on your lands, and they were armed with whatever weapons and gear they brought with them. Feeding and housing them wasn't that much of an expense, either, since armies would often confiscate whatever food they needed from farms and towns along the way (leading to the 3rd amendment of the US Bill of Rights.)
It wasn't until standing armies with standardized weapons and gear became more of the norm that a smaller, better equipped army was really even an option, and by that point firearms technology (and artillery) had progressed enough that armor wasn't very useful. Even then, soldiers wearing a cuirass into battle were still a thing up until WWI, so it's not like the practice died overnight.
It also depends on storage method. Cryogenic and compressed hydrogen have extreme risks completely unrelated to the flammability of the gas itself, while various metal hydride options are mostly a danger if you drop the tank on your foot.
If you're not killing anything, then probably not. It's not a bad thing to be conscientious of, but if static just isn't a problem for you and you aren't handling super sensitive components, stressing about it isn't terribly productive.
Most of what I've been able to find have been people getting busted for manufacturing or possession without an associated violent crime. It also appears a number of departments can't (or won't) recognize printed firearms and just call everything without a serial number a "ghost gun" and call it a day.
It hasn't affected my usage so far. I even sometimes use yt-dlp when YouTube proper won't serve a video without pausing to buffer every ten seconds, so in some ways it works better than the web interface.
