So what kind of printer and for what price would I need to buy so I could print the gun?

Can I print tits?

imagine your printer with a stack of carbon, some water, oxygen, Sulfur and all the most basic elements.

Imagine a printer capable of combining them into your favorite dildo. Or into your favorite meal.

>>5795546
You'd need a very high-end one.

This gun was designed as a political statement, not as an economically viable weapon.

If you want or need a gun and can't get them legally, make a four-winds shotgun (pic related).
I also have some guides for some SMGs if you want them, but you need some specialised tools if you want to make them.

Once 3d printers become viable you will see a radical change globally.
Chinas manufacturing will disappear as printers can self replicate.
Shops and retail except fresh food will disappear.
Warehousing will disappear.
Shipping will drastically plummet.
Owning commercial real estate will be considered retarded.

Clothing, tools, possibly food- houses are already being printed and have a marble like finish.
All these things will so radically effect countries economies that governments may well hold them back with taxes.

alright..... i need to lookk into these 3D Printers...

Any researchers care to speculate on what kind of advancements we might expect in the long term? What about a chemical vapor deposition printer? Anyone think a CVD 3d printer for macroscale objects is plausible?

How about some more exotic ideas like, laser induced electroplating?

The hype surrounding 3D printed guns is pretty silly.
It was possible to make guns at home [much higher quality than 3D printed ones] long before 3D printing came into existence.
And people always ignore the fact that the barrel on that gun is short, loose and for practical purposes smooth bore, and likely to explode.

Again, it's a political statement.
The gun grabbers are shitting their pants with the idea that "some average middle-class white kid" can just print off a fully-working gun and go on some kind of shooting spree or something.

It's turning their entire worldview on it's head, because they're finally actually getting the idea that people can, and will make their own guns even if they're illegal.

I want 3d printers so fucking bad!

Ok, then, retard. I bet you believe in the technological singularity too.

>>5796662
Don't think you're going to be printing a billion transistor wafers in your room this century. But you never know.

30 years is a long time, it's going to be pretty hard to speculate what we'll have in 30 years, so I'm changing this to 10 years.

Currently, one cutting edge process that's been demonstrated in the lab today is high speed printing. 3d printing usually takes a long time usually hours, this new process takes it down to minutes at the expense of accuracy. But with ten years of development we should be able to keep the accuracy fairly high.

Printing big stuff is another trend. Especially for anything made of titanium, as one wastes less titanium this way than machining it. Pic related is a large titanium component for a Chinese stealth fighter.

We have the technology today to print something the size of a 747 if we wanted to the same way today, the only reason why we aren't is speed of printing, fatigue concerns, and carbon fiber is probably better.

Printing precision investment casting ceramic molds is a technology that is less than 5 years away from commercialization and is going to disrupt quite a bit of industry.

I never said you would be able to do all of this with a small personal printer. There would be industrial printers and you could select say a item of clothing you like online have it printed up to fit your body exactly with the colors/patterns you want and it would be delivered to your house.

Similarly with electronics and most everything else.

What are economies of scale? Custom-made items will ALWAYS be more expensive than mass-produced ones, even with this magical 3D printing shit.

>>5796698
What?
Seriously what?

I suspect future 3d printers, even 20 years from now, will not be capable of printing everything, especially not microchips or precision ball bearings. But there is a solution to this, we can embed components into the print as something is being printed. This has been done before, only it hasn't been automated.

Currently, most 3d printers are good at printing a single material at a time or similar materials because of the processes.

You can print photocurable polymers that are both rubbery and stiff(pic related) or you can print several different metals, but not both at the same time.

And being able to print such things together is likely to be difficult for some time to come. Sure, ultrasonic consolidation offers some interesting possibilities, but it's a very wasteful process at the time, though it can probably be improved.

Already exists, look up laser induced CVD freeform fabrication. As it's a thermal process it's hard to control. You could probably make a macroscale object, it'd just take a long time

>>5796611

Because it's cheaper than the name-brand fashion designers, and I can't see any noticeable difference in quality.

>>5796778
Because not everyone shops at Kmart.
I wonder who does more business? Amazon or Etsy of the US or Australian arm of KMart?

>>5796760
>printing one item costs the same per unit as making 1000

Yes, but the issue is that making 1000 items by traditional assembly-line methods will still be cheaper. Mass production isn't going away, because it scales- when people want a lot of stuff, it's cheaper per unit to make a whole lot of it. Meanwhile, with a 3D printer, if you make one thing, it costs X dollars, and if you make a thousand things, it costs 1000X dollars. 3D printing will revolutionize small-scale, niche, and garage manufacturing, but factories aren't going to go away.

That said, I expect small-scale custom printed stuff to get increasingly ubiquitous and cheap, and I expect it to get a significant slice of the economic pie. But the factory isn't going away.

>>5796778
because some people prefer to have fitted clothes without shitty prints on their shirts or solid colors.

excuse me autist, /fa/ would like to have a word with you.

>>5796786
Amazon. Which is the same thing; I go on amazon to order mass-produced designs.

Etsy does orders of magnitude less business, because designing or ordering something custom takes time, and the convenience of picking something that's just Pretty Good, but predesigned and premade, far outweighs the additional appeal of making something Perfect, but more expensive and less convenient to order.

For stuff like cups, plates, shirts, and shit? I expect traditional manufacturing to reign supreme. It's stuff like toys and cool custom shit that I expect 3D printing and other advanced manufacturing methods to win out.

>>5796790

>>5796788
I read last week that Ford motors is pulling out of Australia entirely and moving all Pacific manufacturing to Asia.
Legacy business is very sensitive to economics where small scale highly mobile manufacturing isn't.
Also you're forgetting asset value. The land factories are on is worth a value. And if alot of surrounding factories close, confectionary factories, signage factories, warehouses, tool shops, homewares then the areas value on a whole goes down and the successful factory still takes a hit if it owns the land asset from high vacancy rate and land devaluation.

Answer me this, /sci/:
If home printers are so ubiquitous, then why do book publishers still exist?

>>5796802
They barely do.
Harry potter saved murdochs ass in that industry.
Printing houses like music shops aren't anywhere near the power houses they used to be thanks to tech.

>>5796802
Because printing a book takes time and money, and binding a book is hard, and it's cheaper to just buy a pre-made book which will look way less crappy. Plus, books are very copyright-locked and closed-source; they're hard to get at.

With 3D printers, though, the quality is rising rapidly, and the printing medium is typically several orders of magnitude cheaper per volume than printer ink. I would never substitute a home-printed and bound book for a real volume, but there are already cases where I could substitute 3D-printed stuff for stuff I could buy otherwise, and many cases where I could easily print something that it would be more difficult and expensive to buy (usually custom parts or shells for hobby projects).

Also, it's MUCH easier to make your own useful or good-looking object than it is to write your own good book.

Your point is valid, but the dichotomy is MUCH less strong for 3D printing. Home printing won't suddenly eliminate conventional manufacturing, and there will always be things that larger machines can do that a home machine can't (like bookbinding). However, I still expect the dynamics of manufacturing to change significantly, especially for small businesses whose small order volumes make 3D printing of their stuff practical.

http://utwired.engr.utexas.edu/lff/symposium/proceedingsArchive/pubs/Manuscripts/2007/2007-06-Havener.pdf

A more practical approach is do something like the digital dice and wireless charger in pic related. You print an object and embed chips and other components into it while it's being printed and trace on circuitry.

Pic related was done manually, the chips and conductive ink were put on by hand.

Unfortunately, we don't have very good conductive inks. Pic related uses special $ilver paste, it is pretty expensive.

>>5796733
if you mean printing bioabsorbable implants for replacing broken bones or tissue, it's happening now at the research scale. Has been used successfully in humans if I recall correctly.


>>5796757
notice I said precision ball bearings, the surface roughness of laser sintered parts is pretty high, much higher than any mass produced ball bearing.

>>ever played around with laser-sintering 3D Printers?
I've worked with them.

>>5796826
I think that there's a real synergy here with the sudden rise of interest in gestural shit and VR shit. A 3D display and ability to give commands in 3D by using your arms and hands has the possibility to make 3D modeling MUCH easier- perhaps to the point where a little kid could learn it. Making 3D design easy and intuitive is an important factor in making 3D printers anywhere near as accessible and useful as the utopian visions would suggest.

My work space has a few printers. One my peers printed the gun in OPs pic in fact.

I dont get it. You can make a gun of comparable quality with like metal pipes and stuff. You can even go to home depot and buy a tube of the same plastic used by a 3D to print into a gun barrel.

If anyone wanted to make a gun, 3D printing is now the way to go.

>>5796823
>With 3D printers, though, the quality is rising rapidly, and the printing medium is typically several orders of magnitude cheaper per volume than printer ink.

The plastic used in 3D prints is pretty expensive. You dont actually use an entire cartridge volume of printer ink in a 2D print, but on a 3D print you do.

>>5796830
Been lurking in this thread.
Honestly how long do you expect if ever 3D printers to take over current mass production assembly?
Both industrial and domestic.

>>5796842
>mass production

3D printers just aren't meant for mass production. That's not what they're good at, and that's not what they're for.

Mass production EXISTS because of economies of scale- when you make a lot of shit, it costs less per unit, so it's more profitable to make an assload of the same thing.

3D printers don't scale. It costs exactly ten thousand times as much to make ten thousand widgets on a printer as it does to make one widget- there's no economy of scale, and so for large volumes where the profits from scale vastly outweigh the costs of mass production, 3D printers just don't work.

For small, niche business and products that currently can't exist because of the small production volume they'd produce, however, 3D printing and similar technologies will be a godsend.

Likewise, a hybrid of the two technologies likely will dominate. For instance, one common method of mass production is casting- you make a mold, and then use it ten thousand times. If you 3D printed the mold, then you'd have real benefits- you'd get all the economies of scale, but it's easy to swap out molds for new ones at very little expense.

3D printers will (probably- the new markets they'll open up in niche products will likely create a large long tail of stuff, and nobody really knows how big that market is) never dominate manufacturing, but they'll probably be a significant part of it and will likely be combined with many current mass-production methods.

>>5796795
>toys
if we can get thermoplastic inkjetting to work well, as of yet we're pretty far from it, then the costs of mass producing a plastic plastic action figure would probably be comparable to injection molding it.

Possibly even less than injection molding, because you have no painting and no assembly.

I suspect such a machine will probably be out of reach of the average consumer, but dammit, I really want one.

>>5796856
Even if it can't be home-used and needs to be a Shapeways-like service, the look on a kid's face when he gets the exact toy that he wanted (even though it didn't exist until a week ago) or for getting an assload of Lego-to-K'nex custom-printed adapters or custom LEGO bricks made will likely be enough to drive a market.

3d is for rapid prototyping and small run custom components. It won't ever become economical for anything else.

>>5796830
I'll concede that the surface finish control is terrible, but it is getting better. way better.

why do nerds have such boners over 3d printing? table top metalworking lathes and mills have been around for decades. you can actually make shit that won't disintegrate or literally explode in your hands.

> 30 years from now, what will we be able to make these things do?

It's not what 3D printers themselves will be able to do. It's that they'll be able to make any other form of more specialized equipment.

Once you can do that, you can make any form of industry you want.

As >>5796479 said, totally decentralized manufacture with all that entails.

Imagine third world children with drug labs and weapons programs. That's where we're going, and why governments and corporations, and the capitalist economy we live in, is on it's way out.

>4. Whatever the fuck else you want to speculate about related to 3D printers

You've heard about bio-printing, right? Well, imagine having an auto-doc in your home that can preform any form of surgery you wanted, combined with an auto-pharmacy that makes drugs solely for your benefit.

Combine this with genetic engineering, and we might just see the hospital move into the home. Moreover, not just the hospital, but also the 'bodyshop' of cyberpunk myth. Imagine turning yourself into a superman, without going though anyone else.

This should show just how much of a threat this technology is to the current economic, social, and political status quo. There will be no way to stop it, regulate it, tax it, or subvert it.

>>5796886
Why I do is I'm blind in my right eye.
I literally can't use power tools due to safety.
It suits me to make 3D models on my computer that I can dream of printing out.

>>5796721
if a printer can print everything, can it print itself?

In 30 years will a 3D printer be able to print a smaller 3D printer?

>>5796842
I don't think 3d printers will be used to get rid of mass production.

It is likely that we'll see 3d printers used along with other industrial processes to mass produce stuff.

3d printers are already being used to produce components for airplanes at a pretty large scale

>>5796855
There are very much economies of scale with 3d printers. Any unused area in a print bed is essentially wasted material, so the more stuff you can fit in a print bed makes you more money. Big operations make sense in 3d printing.

That being said, it has been demonstrated that we can vastly increase the speed of 3d printing. In the future, it is likely we could increase it even further and get the same material rate as injection molding. But, you can use less material, make more complicated components, switch over to another product line instantly, and avoid/decrease assembly costs(more than 50% of product cost).

If this was a thermoplastic inkjet process, it's likely the energy costs would be similar to that as injection molding

>>5796904
They can do that now...

Could it be possible that a time-traveling 3D printer went back in time and printed its inventor?

>>5796886

I don't think anybody here is hating on machining technologies. I, for one, am a huge fan of machining.

but you have to admit that 3d printing allows for the creation of geometries which would be impossible for conventional stock removal techniques

In addition, there are some materials which simply are not machinable, at least not on an industrial scale. Material deposition method are the option of choice.

>>5796473
Probably won't happen. It still costs time and effort to print something using a 3d printer. And the more complicated the object is you want to build, the more time it costs. Thus one may get some objects faster by simply buying them.

>>5797958
>Probably won't happen. It still costs bandwidth and time to download something using the internet. And the larger the file is you want to download, the more time it takes. Thus one may get some movies and games faster by simply buying them.

>>5797958
Actually, more complex objects are currently more expensive (all other things being equal) due to the necessity for skilled workers. Once we have 3D printers, you can just download the blueprint and press a button, and it doesn't matter if you want a computer chip or a plastic circle.

sex toys everywhere. that's about it.

For anybody who was wondering, this is an obvious troll post.

Not only is the thesis and argument trash, but Gutenberg made the printing press. Martin Luther's contribution to society was altering Christianity so it no longer hated capitalism.

yes, yes you can

You're going quite far on faith. 3D printers are a very long way from computer chips.

how in the actual fuck will owning commercial real estate be retarded

I think one of my favorite movie quotes is from Superman Returns when Lex says, "You can print money, manufacture diamonds, and people are a dime a dozen, but they'll always need land. It's the one thing they're not making any more of."

you motherfucker you saved that pic on funnyjunk i can tell by the filename

isn't the plan for asteroid mining for robots to collect materials and use a 3d printer to print more of themselves?

1. Honestly the major problem with 3D printing is the shitty materials we can print. Will we ever be able to print with something other than shitty plastics? I doubt it, there are other production methods for things that aren't shitty.

2. That gun is a piece of shit which you would be lucky not to explode in your hand, much less actually hit a target with, and its not like it was somehow impossible to make a homemade gun before a 3D printer, in fact its still cheaper to make a homemade gun without a 3D printer, or just buy a gun.

3. We already have pizza vending machines, Its basically the same thing.

4. 3D printers are largely stupid. I mean okay if you need to prototype something, sure great. But the last thing I need in my life is more cheap low-quality plastic doohickys.

there is no "THE plan" there's just ideas people throw around.

>>5800171
There are already 3d printers for metals and hard plastics. They're not all "glue gun" types.

I think 3d food printers will be much more relevant to sweets than anything else, particularly cake decoration.

Imagine printing down to the atomic level.

As I understand it 3D printing with metal is an involved process that is not particularly more home-user friendly than most of your other methods of making a thing out of metal. What's the point then? I mean its not like we didn't have ways of making complicated things out of metal otherwise?

Yeah. I know. But its not "THE plan". Its just something NASA wrote a study on.

Ok seriously what is with all the luddites itt? I though this was /sci/ not /lud/. I've seen amazing 3D printer threads on /g/ and even fucking /pol/ but you guys have no vision.

>>5800235
You don't understand what luddite means. Not being excited about it is different from being a luddite. No one is protesting the damn things or trying to smash things. Seriously, bro, learn what words mean.

in fairness, microwaves are terrible.

where can I get detailed info on printing materials properties? plastic in particular.

>>5796904
>>5796903
They can do that already.

I suggest everyone in this thread google "micro gravity foundry"

>>5800339
Wow cool!

>>5800151
no no that's the plot for every man vs. machine sci-fi ever

oh wait...
