Developed film has a bar code type of encoding for DX info. The talk about the whole roll is the ability to scan the entire thing in one go vs having to load in multiple strips.
This is a very surface level analysis like saying that the automobile was just an iterative improvement over a horse. Or a computer is just a better abacus. Fundamental research is all about diving into the weeds and finding new problems to solve. It's true that some of the "low hanging fruit" no longer exists (you won't see someone like Euler or Newton who's names pop up all over the place), but I can promise you that real gains are being made on a lower level. These small gains in fundamental research snowball into bigger advancements. As an example, the transformer architecture used by LLMs was first published in 2017.
Automobile was improvement over the horse because things needed to get places. To improve on current automobile will require either massive government investment and regulation in the sense of flying cars, or full electrification with paradigm shifts in transportation, like induction charging roads or battery hot swaps or whatever else. The modern Corolla Hybrid is pretry much the peak optimal point of transportation.
What do humans need right now to improve their lives substantially?
high temperature superconducting would cause a big leap. cheap energy would also help. cheap compute-in-the-walls. machines doing all the dangerous jobs.
Cheap energy is possible now with solar. There is a reason why it hasn't been done yet. Nobody has a need for it. Remember, you may think it would be nice to have an electric car you can charge for microcents a mile, but most people dgaf about putting gas in their car.
Machines doing dangerous jobs also is a thing these days.
High temperature superconducting can potentially be useful in a few applications that involve high current, which mostly deal with transportation. The only real advantage of this is drone delivery service becoming cheaper, but that has big hurdles to cross.
There is a reason why being a streamer is the top choice of "what I wanna be" when you ask kids. Everything is about the internet now in terms of motivation. And unfortunately there, we already hit a hard limit of the speed of light.
If you found one for that price with the controller and pendent, please send me a link. I’ve looked a lot and have not seen any UR for remotely that cheap.
Looks like spot melt laser powder bed fusion (L-PBF). Electron beam doesn’t make sense for something on a smaller scale like this; it wouldn't have the resolution. Spot melt is interesting. Renishaw is the only manufacturer I’m aware of that uses a pulsed laser vs continuous wave (and I’m not even sure if they’re still doing that for their newer machines). I would’ve guessed it would’ve been printed on a Farsoon since it’s in China. I just wish the images had scale bars to give a little more info.
I have both a resin and FDM printer. The FDM is hands down easier to work with than dealing with resin. FDM ABS is also a far better material than ABS-like resin. (Disclosure: I've never tried a proper industrial resin from LOCTITE or something.)
I've been very happy with my Qidi Q1 Pro. I paid about $350 pre-tax off Amazon almost a year ago (Black Friday). For me, it was the most machine for the lowest cost I could find. It almost fits your desired print volume (245 x 245 x 240), but it is fully enclosed and has a dedicated chamber heater. I have almost exclusively printed ABS at a 60 deg. C chamber temp. It runs open source Klipper firmware, but I'd imagine repairability wouldn't be the best. Best of all, I have not needed any calibration. It seems pretty spot on out of the box.
My Voron is hands down a better printer but also required significantly more investments in components and especially time.
Today’s first year undergraduate is roughly as literate as a sixth grader was a century ago. College was never meant to be a mass remedial education program and by attempting to be one it’s failing at its core mission.
All this nannyware of various sorts is just more evidence, proof even, of how few of those students should even be there.
Not really in my experience. That's how final PhD examinations are typically done. Outside of that, it's pretty rare. That said, PhD students are also regularly interacting with faculty members and discussing their work so it would be difficult to get by without actually knowing things.
Interesting. I haven’t heard of them. Joining would still be a problem for a bike frame. Any idea on how well they work with other severe plastic deformation processes?
