I have access to printers via our hackerspaces (shameless plug: Heatsync labs, Mesa AZ), but have only printed 1 thing that I can think of that was useful.
It was a bushing to mate two pieces of steel together. The other things I've printed have either been novelty (hey, I can print a pendant!) or have fallen apart.
I can't wait to buy one, even if it's just to print gifts for friends and nameplates for the office. Every time I hear more about this domain (typically from folks like iamwil at CubeHero) I become more excited by the possibilities. It's a enabling technology, so looking for a "killer application" is probably the wrong way to think about it: the impact is likely to be more fundamental and spread across a variety of s…
As for crowd labor market, there might be an application. 3D printers are slow compared to other types of manufacturing, and thus, to get any volume to sell, one needs to operate a printer farm, or try to do distributed 3D printing.
When people do operate printer farms, where they have racks of printers to print out parts that they sell. However, the current crop of 3D printers still requires manual labor in the beginning and the end of the print. There's no mechanism yet to automatically remove the piece and start a new job. This may be where labor can come in.
As for distributed printing, I do know of a guy that's trying this out as an experiment, since he doesn't have the capacity to print every piece he's selling, he pays others to help him print, and then it's shipped to him. So that is a possibility as well.
Whenever I think of 3d printers, I think of this essay: http://www.paulgraham.com/stuff.html I'm not sure whether 3-d printing will result in my having more stuff or less. In the long run, I could see it working out either way, but with the technology in its current state, it would definitely result in a net increase in the amount of stuff I have.
I was at a local hackerspace and paid about $180 into a building class, but then it didn't work out and other things came up in my personal life and that of the person giving the classes. I think the $200-$300 range is where it's going to have to get to before 3d printers become wildly popular. Most people can overlook the low quality of the prints and the acetone wash if the cost of the printer is less than that of…
I'm excited by the potential of 3D printers but they aren't quite at the price/convenience/quality intersection I'm waiting for. I'd pay current prices for machines (the relatively consumer-level ones that are like $500-2000) that are faster and produce better output without having to do acetone-based "post-processing". I'd pay less than current prices for the current tech just to dick around with, but I don't want t…
What would you do with a 3d printer in your house? For manufacturing and business use, it kind of makes sense to me. But personal use? After you print off a few cups and toy soldier molds, what would you want to do with a 3d printer?
I think 3D printers are firmly in the "Linux desktop" stage for now. You will hear it's revolutional arrival announced every year, but it will never materialize.
I'd put them firmly in the same stage that computers were back when you had people in their garages soldering together homebrew computers.
3D printing on the other hand fundamentally has difficulty delivering many things people want it to do, and the things it actually can do are fairly niche. Mainly prototyping, to my knowledge.
If 3D printers could already print forged steel or 14nm transistors (but at great cost) I'd say the future is very bright, because cost and size naturally come down, but they can't do that yet.
Moved back home with my parents, christmas / birthday was coming up. I was looking into some printers (I was going to get the Solidoodle 2) to get. I was talking to my friend about it one night, said to myself "Whatever, I'll just make it!" (not sure why that thought popped in my head). 6 weeks after that, I have this thing: http://imgur.com/a/FZfp9 in my room. Wish I would have documented the build process better.
I wanted one because I'm making a cool product and needed to make some cases for it.
I use LinuxCNC to run it with a HobbyCNC stepper driver board, and it actually works pretty well! If I could make one 'enhancement' for it, I would make native gcode arcs work in slic3r, as I can hit 60-80 mm/s on a straight away, but around corners it gets to ~25 mm/s.
I've found two 'killer' uses. My nieces and nephew come over, they want to make something (my nephew asked for keys one day). We pulled up thingiverse, he picked one out that he liked, 45 minutes later he has keys.
The second one is being able to design something and see it almost instantaneously. Is this going to fit? How does this look? Would it work better this way? You don't need to sit and twiddle your thumbs for so long, as you can test out a ton of ideas.
One of the pains is the calibration for this thing - I made this script (which definitely needs some work) https://github.com/MercuryRising/dic3r to aid in calibration. You can calibrate your build plate (it makes a skirt of your platform size, so you can even it out while it's running) and I think it does extrusion multiplier calibration. The one thing that I think is really cool for it is variable density (specify a Z height to merge two different slices of stl). You can make stuff like this: http://imgur.com/a/B26e5 with different infill patterns.
