Not to sound negative, but what a crappy link.
1: QR codes doesn't do anything that a standard barcode does (sure, more data pixels => more data), which has been around since 1974 (so almost 40 years). Nothing here that 'seemed impossible'.



QR Codes can hold 100 times as much data as a barcode in the same space. Though... I am still not impressed because the QR code isn't amazing, the device you use to scan it is.

1-3 on this list is effectively "Smart Phone".

Yeah. pooty list.

I don't own one (though I'm considering adding an extrusion head to my CNC router, which would give me a pretty hefty printer capable of around 30"x22"x6"), so don't quote me on this, but, as far as I'm aware, typical hobby CNC printers run off generic gcode. The unique bit of software that's specific to 3D printers is a slicer application that converts .stl files into gcode for the interpreter to run.

As for the really nice machines that are priced similarly to comparable CNC machining centers (read: a pooton), I can only assume they run off proprietary software/firmware for the most part, though, obviously, they're very similar at a basic level.

Odd thing is- My ex was working on digital photography in 1987 ish. So for me- no surprise at all.

Cool, man. The film is interesting too.

@FoolsPrussia - Not yet, it's on my list now though. I just saw that film a few weeks ago so I've been meaning to get the book.

That's not the only thing they're being used for. I know of this local company that takes the MRI scans of organs, and prints out scale models, so surgeons have a physical model to practice on for things like heart surgery.

@whodat: Have you read Ray Kurzweil's book "The Singularity is Near"? Very fascinating stuff.

3D printers are, at present, niche tools for ease of use in prototyping and low-scale part production for hobbyists. CNC tooling is for more industrial applications and richer hobbyists.

And for the record, odds are the average CNC guy is going to be more interested in a 3D printer than the pleb who doesn't even know the term "CNC" exists
As a night shift CNC guy I have to agree, like to see how this 3d printer operates, and what is needed to make stuff, is it run by Fanuc code or otherwise?

10 years ago my flatmate was making resin rapid prototyping models in college.

As a wannabe machinist, I can say with a bit of confidence that CNC tools aren't really directly comparable to 3D printers (go away, pedant who's about to point out that a 3D printer is a CNC tool, I know you're there).

You can't just send a part into a set of interpreters and hit go. There's more setup involved (though capable CAM software can help with that). Not to mention there are certain operations that even a 5-axis mill simply cannot perform (such as enclosed or nearly-enclosed spaces).

3D printers are, at present, niche tools for ease of use in prototyping and low-scale part production for hobbyists. CNC tooling is for more industrial applications and richer hobbyists.


And for the record, odds are the average CNC guy is going to be more interested in a 3D printer than the pleb who doesn't even know the term "CNC" exists.

I don't understand why people are so impressed with a 3D printer. Have they never seen a CNC machine? It makes sh*t out of metal! Who the hell wants a wrench made of plastic?

What's next? Well, according to Ray Kurzweil in his film "Transcendent Man" we'll reach singularity, possible as soon as 2030. That's the point where it will supposedly be impossible for humans to keep up with the rapid advances in technology unless we have some of that technology implanted in us, like a real life cyborg from a scifi movie. Then, of course, that opens the door to the potential for immortality...

1: QR codes doesn't do anything that a standard barcode does (sure, more data pixels => more data), which has been around since 1974 (so almost 40 years). Nothing here that 'seemed impossible'.
2: Augmented reality hasn't really hit the mainstream market, so to say that it's something you use today is a far stretch. But yeah, the 'idea' of using it is there today... and functional 'augmented reality systems that hasn't hit mainstream' has been around at least since 1990.
3: What FoolsPrussia said
4: Digital cameras? Seriously? Digital photography certainly didn't seem impossible 10 years ago, on the contrary I would say that around 2002-2003 digital cameras were by far the most sold cameras.

Soooo, in conclusion: 1 of these 5 points have some merit. I don't think anyone 10 years ago would have imagined that mobile-phones would be as advanced today as they are. The rest is just crap.

3D printing has been in the works for much more than 10 years. I know I heard about it back in the 90s, and I believe it goes back to the 70s. It's just now becoming affordable.

Link: 5 Common Technologies You Use Today... [Rate Link] - ...that seemed impossible a mere 10 years ago--maybe less. Technology--it's moving at breakneck speeds. What's next?
