Lets just hope they remember that Apple own the rights to the shape rectangle
Tremble, thing-makers, because The Pirate Bay has started to share the source files for physical objects. The controversial file-sharing site, known for aiding the distribution of music tracks, films and books, has decided to start a new category for files of 3D objects. Only those with 3D printers will be able to make use of …

Pythagoras presumably is enough prior art for the triangle and it was long enough ago that it's now in public domain.
Triangles are the way to go chaps, and 2 identical triangles can be used to make a nice apple replica rectangle :¬)
people said the same thing about videodisc vs. VHS. Believe it or not, sometimes a new technology fails to achieve world-beating status, and the only way to tell which ones will and which won't is to wait and see whether it happens.
I don't have a lot of faith in the home 3D printing revolution, myself; while there are undoubtedly uses for a widget that can spit out ABS in whatever shape you like, a widget that can *only* spit out ABS is only good for so much, and no one seems too inclined to explain precisely how we're going to go from that now to printing out cars and TVs in 20 years' time. Sounds like it's made out of badgers to me.
With respect (and indeed, sincere respect. Sincerely), 'ABS only' may be simply early phase.
Yes, this is about home 3D printers. Yes, the link here isn't for a home service. However, that may just be a step waiting for home printers to climb.

"Please note that the 3D printing materials we use for manufacturing the designs make the products suitable only for decorative purposes and they are not suited for any other purpose. The products are not suited to be used as toys, to be given to children. The products should not come in contact with electricity or food & drink and should be kept away from any heat sources."
Sorry, but I need a bit more out of my footwear than "suitable only for decorative purposes".
... these? The Airbus 380 link is, I think, interesting:
http://www.newscientist.com/article/dn20737-3d-printing-the-worlds-first-printed-plane.html
"So Keane's team set out to see how quickly they could design a 1.5-metre-wingspan, super-low-drag UAV, print it and get it airborne. A UK-based 3D-printing firm, 3T RPD of Greenham Common, Berkshire, joined the venture, agreeing to print the UAV out of hard nylon."

"What's old is new (and better) again thanks to 3D printing techniques under the employ of Airbus. Seen above are two parts. The simpler one was created using conventional manufacturing techniques. And by conventional I mean, of course, soon-to-be obsolete.
OBsolete, and replaced by 3D printing, which Airbus has apparently perfected to the point that it is using 3D-printed parts to help fly the massive A380."

Bet they'll taste just scrumptious, too -- and for the sarcasm-impaired, by 'scrumptious' here I mean 'lousy' -- or else, between materials for the 3D printer and the ingredients that go into chocolates expensive enough to taste good, cost twice what you'd pay for a sampler box. Might be both; won't be neither.
to prefer wearing shoes to clattering around in shiny new ABS-printed clogs. Sure, the clogs don't insulate, don't fit comfortably, don't flex without cracking, and don't have traction worth talking about -- but who cares? This is the wave of the future we're talking about here!
My hobby in Model Railways, yes I know I've said it, as acceptible as Golf in Luton.
However the point is that there are a number of small start-up companies that are producing single or short runs of niche models, at a cost anywhere between £30 - £3000 a go. A lot of that cost is producing the drawings, and the cost of the professional 3D printer. If releasing them means they will arrive on Pirate Bay , then they won't, because they would loose their IPR.
Quite a lot of models are now produced by 3D scanning the real thing, so mass market 3D scanners will be the real challenge to commercial producers, as anyone can then 3D scan a model, Airfix or Otherwise, and make their own.
Yes a complex model can take 24 hours to produce, but it is a fire and forget process.
It may be unfashionable buit we are pushing the boundaries in 3D print. Our needs are for incredibly fine resolution which helps create a demand for something everyone needs.
At the moment, the quality isn't there but it's only a matter of time.
I've had a few bits printed. Photos on my blog: http://philsworkbench.blogspot.com/search/label/3D%20print
Hornby are using it to prototype, I know they make some parts for pre production such as dummy chassis using it.
Modelling is one area I think it would work, maybe I will get my SPV steel plate wagons 30 years on, only got my STV tubes and HTV coal hoppers recently after hassling Parkside for years.
They've just lifted the plot of the latest Charles Stross novel to yank your journalistic chains. (Quite a good read though, Rule 34: "If it exists there is porn of it.")
Never mind that you don't actually need to inhabit a world of home fabrication devices and downloadable desings to have your IP pirated and traded by a criminal underworld.
Just head down to your local market or car boot sale to see that it is already here, powered by nothing more sophisticated than far-eastern sweat-shop labour.
The quality of affordable 3D printers is atrocious. Look at pics of objects produced by Makerbot for example. It doesn't have the precision to make anything remotely resembling lego and works in monochrome too.
You'd have to spend a lot more to get a decent 3d printer, and chances are you'd have to use a service like Shapeways instead who would point blank refuse to print out anything which is recognisably copyrighted.
The quality of MakerBot printers is atrocious... But the quality of the Ultimaker is stunning. I don't have any pictures of stuff I've printed on my Ultimaker, but it easily rivals shapeways. Take a look at these:

I've printed a whole army of multi-coloured yodas now at 0.02mm layer height.

I'll wait for the nanobots. Feed in all that left over Carbon from the sequestration systems and let the nanobots build diamond bodied cars by re-assembling the atoms in the correct order.
Shove some in the bin and they can do all your recycling separation for you too by separating everything into it's component atoms leaving nice neat cubes of each element ready for your next project.
Mines the one with the hole in the pocket.
There are places that do 3D model making for you and you can upload your (STL ?) file and they post the item back to you. There are already a number of online repositories of 3D files for all sorts of things that you might want to do; the piratebay just seem to be catching up with the times.
However, 3D scanning has become very easy, so maybe TPB will have people's scans of things that the other repositories wouldn't touch?
Any eventual nanobot type system would come with a kill switch (or more likely an activation switch) to prevent that kind of 'grey goo' apocalypse. E.g. powered by some specifically tuned form of radiation, without which they are inert, maybe similar to your microwave oven.
More likely some kind of very specific chemical fuel that doesn't occur in nature, patented of course so that you have to buy it in large quantities from the sole manufacturer. Oh and taxed by the government on top since we'd all be brewing up our own synthetic fuels sans tax from the contents of the kitchen bin in Back to the Future hovering time-travel DeLorean style.
Cause that worked so well in Jurassic Park. On a more important note, why is it always grey goo? Why can't it be purple or something. If these things are going to take over the world, at least they can do it with a little style. Imperial Purple or something. I might even go quietly if the nanobots are pink, just to be able to hear Santorum scream about the evil gay ants.
"Any eventual nanobot type system would come with a kill switch (or more likely an activation switch) to prevent that kind of 'grey goo' apocalypse. "
Oh, is that so? Let me just run that through my reality machine.
Getting the results now.....
"I assume that any eventual nanobot type system would come with a kill switch (or more likely an activation switch) to prevent that kind of 'grey goo' apocalypse. At least that is, until someone makes some that doesn't"
I was thinking of that too
ABS is common on cars - eg bumpers, my car (actually most of that model) are missing some small grills in the bumper, and the earlier cars shed headlamp washers like they are going out of fashion.
There you go, 4 parts for 1 car model, but not the same car, and not long out of production.
Is going to make an enormous difference to the world of manufacturing. There's a long way to go before it can be used for anything with serious structural properties, or needing multipl materials, but it will come. Maybe not in my lifetime, but who knows.
But it will change this world of ours, that's for sure. The irony of chinese plastics factories being undercut by people making their own plastic tat appeals to me I must admit, but unfortunately there's a very serious side. The long term consequences, who knows. Lets imagine much manufacture is done by everyone at home, and design is mainly done by amateurs because no-one can make a living at design because they are ripped off.
There are all sorts of dystopian visions opening up... increasingly we seem to be getting a society where there are fewer and fewer unskilled jobs, and yet arguably there are more and more unskilled people... Here come the Marching Morons...
There's already been a reg article on 3D printable clothes and a video circling the net showing how objects with moving parts can be made using a 3D printer. So I'd say that it's not just small plastic desk toys that'll be uploaded to TPB, what about hand tools(adjustable wrenches have already been made), gadget accessories(cases) and random objects like hair brushes and dildos :)
I wouldn't say it's going to be an apocalypse or revolution, but I do think it will be as awesome as, say, the invention of the PC or cell phones and possibly automobiles.
Either way, the dead record industry is going to cry when they realise that I can copy the actuall record itself as well as the song :P
"Either way, the dead record industry is going to cry when they realise that I can copy the actuall record itself as well as the song :P"
None of the 3D printers I've looked at can come close to doing that. To print a record you're talking about micrometer level detail. Really high end home 3D printers I've seen can handle .8 millimeter sized details, but nothing smaller than that.
Quick, everyone, pirate some expensive modeling software so you can make free 3D printable models!
Also, how long until (or how long since - I'm not checking) this format does the "Internet" thing and becomes 90% porn?
I think when I get a minute (never) I'll make a model of goatse, then upload it under titles like "Big Tits" or similar, just to stir things up a bit.
There are (I've heard, haven't tried) decent programs for 3D modeling for things like animation. But when it comes to mechanical design, you want (need, in my opinion) a parametric modeling system, like Solidworks or Inventor. Believe me, I've looked (and re-look every few months,) and nothing free comes anywhere near the capabilities of Solidworks.
For reference, parametric design mostly boils down to relative dimensioning, so you can define the center of a hole some distance from an edge, and if you move that edge the hole follows it. This allows you to make adjustable models, which in turn allows you to iterate your designs quickly (until you hit some limitation, and your hole is now in free space, at which point everything goes to hell and you just have a beer.) Anything with static dimensions ("this hole is at x,y,z - then adjust it manually after you move the edge it's supposed to be aligned with,") or, gods forbid, primitive-based modeling (BRL CAD - "I have a rectangular prism with these corners, I subtract from it a cylinder of this side at these coordinates... now imagine making a laser printer paper tray") is just asking for trouble.
Then again, I'm a mechanical engineer (and I've had models 3D printed!) Maybe people art abilities (not me, in the slightest) would do better with Blender. I've heard it works, but I can't imagine tolerancing moving / meshing / interlocking parts with it.
I also doubt that it has a button that'll tell you the second area moment of inertia of a surface (IE cross-section,) which saves about 2 pages of calculus (assuming an oddly-shaped beam) when you're trying to print beam springs. Couldn't live without that!
While decent quality 3D printers may become affordable are they really going to be worthwhile or cost effective to own?
Decent quality photo printers are affordable, but it works out a lot cheaper for me to use one of the many online services to print and deliver my photos than it does to buy and run my own photo printer and when I do want a photo printed there's very rarely any sort of rush so I'm happy to wait a few days.
Even if you can nip into PC World and pick up a 3D printer in a few years time I doubt most people will bother as it'll probably end up cheaper to do your 3D printing through an online service who wont touch anything that's obviously copyright (like the way most photo sites will avoid duplicating copyright photos).
This story does make me think of something you might see on thinkgeek, google or slashdot on April the 1st though.
Once a metal 3d printer (with sintering kiln) is available it will be possible to download a saturday night special, and eventually an automatic rifle receiver. (I know, the material strength will need to be increased significantly for the gun to not blow up or fail after a single use.)
>>"(I know, the material strength will need to be increased significantly for the gun to not blow up or fail after a single use.)"
So what?
Wouldn't we maybe be better off if the people dim enough to try setting off explosions in home-printed firearms actually *did* try setting off explosions in home-printed firearms?
The Rep-Rap type plastic extrusion machines are just one example of CNC. They all share a way to position the working head in 3 dimensions relative to the work piece. What is different is what kind of working head: drill bit for cutting metal, plastic extruder, laser for sintering, etc.
Computerized Numerical Control (CNC) machines have been around for decades, working with materials like metal mostly. Like the old mainframe computers, though, they were expensive enough that only businesses used them. There are hobbyists building home CNC machines the way early experimenters built their own PCs. The revolution will be when enough of the machines are cheap enough to make parts for each other at a community or home level. This already happens at the industrial level. The factories that produce CNC machines use more CNC machines to make their parts. It's just been too expensive for ordinary people to do that so far.
You missed the fact that these machines are additive rather than subtractive, the primary benefit is you only use the material you need.
This is also beneficial in industries where components are typically made from a solid lump of material and where casting is not practical due to risk and/or cost due to volume.
I know the article was written in a pretty tongue in cheek tone, but the phone accessories market for example, is growing rapidly, and if printers can be made bigger then why pay BMW 3k for a replacement front wing or bumper... if there's a market for it then there's someone to exploit that market. I think (technology advanced required) it will be a new era or of 'illegal downloads'.
>>"and if printers can be made bigger then why pay BMW 3k for a replacement front wing or bumper.."
Well, I guess unless you could prove they were just as good as the original as far as crashworthiness, etc is concerned, your insurance company might have something to say about it.
You do need to look at the bigger picture - if you 'save' £3k but end up getting insurance refused or made more expensive, and also lower the resale value...
And I somehow doubt that BMW would be likely to sit by and say - "Fair enough, they're probably as good as our parts" even if they thought they were.
Ultimately, if there's a crash and doubts exist over a part's safety, if BMW have made the part, it's between them (and their engineers and lawyers) and your insurance company.
If you made it, it might be between your insurance company and you.
Even if you're technically right, you might have a good chance of losing.
I did some work on one a while back.
Seems that most of the quality problems are due to non repeatability on the axes due to the cheap motors used.
A simple way to fix this is to use one of two things:- an accelerometer on each axis which actually measures "time of flight" or an optical sensor similar to the ones used on HP printers.
Both of these methods would increase accuracy, an infrared thermometer pointed at the extruder tip would also allow real time feedback of the precise extrusion temperature which would help a lot with warping of the build.
Wonder why someone hasn't attempted to build one which extrudes a plastic containing iron, and then uses induction to keep the build at a set temperature?
