It's always better/cheaper next year, especially 3d printers which are rapidly advancing

So the question is more, does it do what you want to make now?

good point... hence the conflict... so much stuff is made from plastics anymore. its hard to believe some farming operations are completely stopped by some broken piece. itd be great if a feller could just go back to the house and print one off. and i suspect most would do that well enough. i keep looking for one that promises to be upgrade-able to some of the composites that are coming down the pike (blends with wood for example), but dont see too much of that. fact is ill probably just settle for some mid grade one and wish next year id have waited all the while being glad i didnt... :D i hate buying things.

RepRap project

the time is in the blueprints, unless what you want to print has been publicly posted

Thingiverse Gadgets

Right now I see it as a way to make parts for the retro market

Atari 2600 paddle replacement

custom ATX case IO back plate
 
im actually familar with the software. i was a cnc operator for a number of years. blueprints are the least of my worries. my real issue is that it wont do next years "revealed and promised stuff" today...:D

one of the first videos i watched was a news item about a guy printing off the bulk of an ar 15 lower receiver (the part with the serial number on it) at home. since it was for personal use he violated no laws. lol... this is the real reason gun control won't work...

MakerBot pulls blueprints for 3D-printed gun parts in wake of school shooting

Oh No! All the 3d blueprints for gun parts are gone from MakerBot! guess that means the 3d printed gun project is dead!

Home of the Wiki Weapon. A nonprofit, collaborative project to create freely available plans for 3D printable guns.

with a 3d cnc you can do metal parts, a better investment than the 3d printer at current stage of the technology development

although the best investment might be a high end color printer, print some foreign currency ...

But pick one that they're not exactly sure what the correct image should be on their currency anyway

but beware the yellow dots

the wiki link led to another click and i was here... laughing my arse off

You know those gun buybacks they have where they give you $25 to $100 for each gun you turn in? I've been to a few and most people turn in the most worthless, broken pieces of junk you've ever seen. I figured it would be fun to make a gun that cost a few bucks to make and turn it in. The one in the video got turned in for a $40 gift certificate, which I traded to another guy in line for a decent shotgun. Anyway, this gun was made from a laser cut steel frame and two pieces of 1.00" x 1.00" steel bar stock machined/drilled to act as a barrel and slide. Including the spring and the roll pin (which acts as a firing pin), this gun has only 5 parts. It fires from an open bolt, as you can see. This video was made years ago which is why it's so small and crappy. I've got a few more laser cut frames lying around, so I'll probably make another one and get a nice HD video of it.

Realistically what's the rate of fire for a 3d plastic printed gun? I somehow doubt it could get more than a dozen bullets at the same rate of speed as a AR15 before it melts internally and is unusable
 
there's a 3D community on G+ here

I'm sure there's people there who can answer many questions

i'd love me a 3D printer

realistically no one is making the entire gun from plastic, just the traceable part. the rest of it can be bought without a background check as its just a component part. in fact you can construct whole guns buy just buying replacement parts, but the receiver will be a recorded sale. its a loophole you could say, and with these new printers it just got "holier"... good guns will always be made of metal and every joe bob i know can use machinery well enuff to make ones that work...
 
No, that's just one more reason why the ammunition needs to be illegal too.

Hoping you're being sarcastic... Because there's absolutely no way someone can take a casing, put a new firing cap on it, pour a little black powder in and cap it with a chunk of lead.

Anyhow, bringing this back around to topic... With the great advances being made each year with 3d printing, personally, I'd be hesitant to get a very high-end one, right now, myself. But, like you, I am getting to the point I'd like to start experimenting with producing some small items, as well.

So, at this crossroads, I've been considering going the cheap route to tide me over a few years while the high-end sorts itself out. With that in mind, I keep finding the Portabee interesting. http://portabee3dprinter.com/

It's based off a lot of stuff learned with RepRap, (in fact, it looks like it's really just a collection of parts to build a recent version of the reprap with a few modifications) and it does small-to-mid sized objects in PLA or ABS. But it's small and cheap (cheaper than most sets of reprap components, and they sell cheap ABS and PLA - $30 and $32/kg) so I wouldn't feel like I was wasting money when, in a couple years, I sell it on, and get something new... I'll know exactly what I want to upgrade to, by then.

im kind of leaning towards this one on the low end line... its $599 base price, abs upgrade is another 100... sticking point for me is build size and this one has a generous
Build Volume: 10x10x8 inches (254x203x203 mm) of course the downside is i'll be waiting until august for it...
