Ask Slashdot: For What Are You Using 3-D Printing?
An anonymous reader writes: I've been thinking about getting a 3-D printer for a while: the quality is rising, the software is better, STL files really do seem a sufficiently good standard ("sufficiently standard," that is — I'm not worried that printers are going to stop supporting it anytime soon), and prices have dropped quite a bit. Importantly to me, it also seems like less of a jumping-off-a-cliff decision, since I can get a completely assembled one from places as wild and crazy as ... the Home Depot (not that I plan to). However, even the stretchiest practical things I can think of to print can't truly actually justify the price, and that's OK — I hope not to require enough replacement knobs and chess pieces to necessarily *need* one, and playing around with it is the main likely upshot, which I'm OK with. But still, I'd like to hear what uses you have been putting your 3-D printer to, including printers that aren't yours but belong to a hackerspace, public library, eccentric neighbor, etc. What actually practical / useful tasks have you been using 3-D printing for, and with what printer technology? What playful purposes? It's OK if you just keep printing out those chess pieces and teapots, but I'm curious about less obvious reasons to have one around. (And I might just use the local Tech Shop's anyhow, but the question still applies.) If you've purchased a 3D printer, are you happy with the experience? If so, or if not, what kind did you get?
They're quite useful if you know what you're doing. For example, you have some kind of toy, gadget, device and whatnot...that's missing the battery cover? Hard to find...even on eBay, so what do you do? Fire up your favourite 3D software and make one. Works like a charm.
If you're working in advertisement/merchandise production... you can make small prototype samples of what you want to have mass produced, this ensures that your oversea production don't get it wrong (and they always do, trust me!) Shipping a sample of what you want mass produced, is a dream come true, and fortunately for (me) most of my competitors have no clue that this can be done, so they still do it the old fashioned way (try to tell the production team with drawings and talk over the phone with a foreign team that hardly understands English).
Pictures say more than a 1000 words they say, well...a prototype object to hold in your hand says more than 1000 pictures.
3D printers are a godsend.
What this world is coming to - is for you and me to decide.
