Very excited about 3-D printing... Already imagining BitTorrent sites that share designs for kitchen utensils and replacement vacuum parts :-p
+Robert Rothermel the pirate bay is getting into that.
Thanks for this video, it might give me a place to put my ideas.
It's nice to see this tool presented in this way.
hello random person. im another random person (who is oviously very bored)
@Yesmar; I find it utterly pathetic that you need to look for cyber sex you're so desperate, but also that you are looking on fucking Google+'s comment systems. :|
yeah jack them joints up!! lol? yo +Yesmar Barns - +Kat Black thinks ur tryin to cyber.. lol wtf!?
+Jose Orduno nice to meet u too.. kinda but we havn't really met.. u kno cuz this is just the internet...
3D printing is the BOMB! You can get into one for around $1000 now and the best part is it can print all the mechanical parts you need to make another printer! How cool is that?
+ Enoxh Eloe Perpetual motion here we come!!
This is amazing, I particularly liked the Quirky company, they're doing something really original and ahead of its time.
Quirky has an awesome idea! That's pretty brilliant!

Thanx 4 posting this.
i've been setting up my workstation so that i can hopeful output STL files for 3d-prints of some digital models. The 3d-printing//digital-manufacturing industry is changing & growing at an amazing pace in the last 2 years & will continue;-)
Everyone is a manufacturer! This is a nice idea, but might take some time to take off
I suspect at some point many of the products you buy will be downloaded and printed in your home.
rob M.
hello Enoxh, yes, i've heard quite a bit of talk//comments along the same lines: with time & better costs/efficiency, it should happen. There have been MMMaaannyy StarTrek "Replicator" jokes too;-)
+Cameron Becker RepRap's position is that 3D printers and humans have a symbiotic relationship. The printers give humans things they need and the humans help 3D printers reproduce. So I think the most valuable thing you can print with a 3D printer is more 3D printers...?
What about printing very small things, like medicines?
Interestingly the first human organ was printed with a modified HP deskjet printer that used bio materials instead of ink!
This kind of machine are great, but is it only used in New York?
+Sun MINI No you can buy them online or download plans to make your own off the web. The more advanced printers like the ones that print plastic powders, metals or ceramics are HUGE and very expensive.
+Enoxh Eloe Ah ha, this is exactly how I thought it would work; using "cartridges."

I wonder if they're also using a laser to check and correct the accuracy of the reaction; zapping erroneous areas by their color?
^ Um, is that spam, did I track that in here?
Does the software (post scan) allow you to bend or change the projection? Example: Let's say I scan a wrench. I can then print that wrench off in 3D plastic. But let's say I wanted to scan the wrench and then want to add (create) a small flathead screwdriver to the end of the handle. Is that possible on the software?
+Josh Smith You would have to know something about 3d Modeling or using CAD programs. The File formats they use are standard 3D file formats so yes you can open the file in a 3D modeling program make changes then send that to the printer no problem..
Thanks. My friend is using this now. He built his own printer and has a finished product he is submitting a patent on. His home built machine is great but these higher tech, and more expensive, machines look great. I imagine this tech will only get better and hopefully the user experience regarding what I described will become user friendly. I imagine a high tech 3d modeling app is not far off.
Thanks Meg. I tried Google Sketchup quite a while ago but have been meaning to give it another shot when I get some time.
+Josh Smith You can use any 3D or cad program, there are tons of free converters available online to convert your model to STL format when you're ready to print.

gr8 thread here ;-) My background was primarily 3d-modeller w/ bit of general CG (digital paint, some design/some lighting & camera/animation) for a few vidgames in 90s & various corporate/ boring clients b4 & after that time due to severe-health-struggles.
NOTE 1 of my health issues is OCD ((obsessive compulsive disorder) so i apologize if this post gets-too-long-winded...0_o...
So, YES as far as high quality 3d modelling/building apps they do exist even for the artist/designer who's young or has budget constraints. Like Enoxh says, the main format is "filename.STL" because it's an old-tried-and-true format from the
days when engineers & manufacturers utilized CAD/CAM prototyping....BUT.....
as Doc FARNSWORTH {Futurama;-) would say, GOOD news everyone!
It turns out that the industry has so many uses ((like the medical-printing mentioned above)) as well as
millions of
toys & hobbyists-creations, and especially boutique, household designer lamps, clocks, gizmos, well, it's driving the costly machines down to the point at which
the Z-Corp's basic-low-end (yet professional) 3d-printer is
now only US $ 5thousand: even tho these machines co$t millions of dollars back in 80s for aerospace &
auto industries, etc.
BUT that means that a true CAD app (which has all it's
strength in accurate-digital-drafting such as for medical or maching/manufacturing) well, these CAD apps WILL allow your 3d model to
stand a much better chance of working on
any company's 3d printer; rather than
using the
more common 3d modelling animation apps: YES it's a bit of a drag. i.e., most 3d modeling/animation apps are geared to the way artists & designers think/work whereas strong-solid-CAD /drafting apps have always been used by the
science + engineering & big-industry folks. Hence Enoxh hit it right on-target :: most artists will endup using
good 3d-modeling-animation apps & then they must output
an old "STL" file-format for the 3d-printing;
many of those will cause bugs & printing problems due to
the different nature of the drafting-world versus the more artistic-oriented-world-of-3d-animation apps. meh i foundout the hard way when i tried to make a print a
year or so ago; my model was very basic/simple, a good test or learning attempt..yet the 3d-printer's software could not translate my model's data over-into the 3d-printer: it would NOT even TRY to print..HOWEVER,
lots of smart coders are doing just what Enoxh said:
helping to write programs/apps that translate different modeling file-formats into better &
more-accurate STL formats, etc etc.
ALSO: Some 3d modelling apps can output a good "IGES"
or "OBJ" format from the model-file;
& there's a 3d printing service in the UK (i think they're
called PD Models) who's 3d-printers can deal w/ any of those formats fairly well,
--so i looked them up & 1 of their modelers, a guy named Lewis, has posted some of their 3d-prints to
the CG Society's advanced animation-forums (aka CG Talk)
(many of the best CG/digital artists in the world show portfolios & discuss professional 3d + animation issues in the CG Talk social-network: i highly recommend-it; well he posted this 3d-object that
his group had printed: dig the detail they achieved on this TINY "knight/warrior-sculpture" in which it's hands had fingers soooooooo small that they measured less-than-HALF a millimeter wide & the whole 3d-printed-object DID print them in hi-detail yet the whole body of the character/warrior was only 4 inches tall, excellent :
...and CG Talk// CG Society:
+rob Darmok That's a nice summary rob!

Klaus Stadlmann has been doing some great work recently and has developed the world's smallest 3D printer! You can learn more about it here..
Power to the people with ideas. Let them be unleashed!
to everyone saying that it would be awesome to print out more 3D printers, main issue will be an energy shortage. i understand 3D printers use high-potency lasers to work, not something you will be able to just plug in your home's energy outlets
+Max Zyrix I don't follow you. But I agree that media becoming mediator smells of a contradiction, or a confounding argument like yours.
+Meg Gamine lulz my english is not as good as it used to be. lack of practice, i guess. anyways, the point i'm trying to make is that the amount of energy needed to power a 3D printer is a lot more than what you recieve at any given household
+Max Zyrix This is not correct for all printers. Most home printers use slightly more electricity than a coffee machine. The large industrial ones perhaps but home printers consume normal amounts of electricity.
rob M.
+Max Zyrix +Meg Gamine Hey folks, Enoxh is spot-on in w/ energy-issue: there r only a certain-percentage of 3d-printers that use lasers or other expensive-methods. But it's def worth looking @ this video:: ;; it shows the system used by "ObjetGeometries" : a gr8 company. They make cutteng-edge-tech, so they DO use expensive methods that shine UV [ultraviolet] light, on each pass over each new-layer to help "cure" (harden) the elements just b4 the next layer is "sprayed"/printed. Enjoy;-)
+rob Darmok I totally agree with rob. No question if you're talking about 3D printing metals or ceramics or even nano-printing or any other hypercomplex application of this tech then sure there's gonna be some electricity involved but it's nothing compared to a steel mill or oil refinery.. As far as something that sits on your desktop and squirts melted plastics in thin layers or an appliance that does the same with say chocolate or ice? Not and issue.
On the recursive printer subject: If one were to make a 3d printer that used lithium polymer as a medium, the result could be its own battery. I imagine a metallic bacilli, doubling it's length, replicating all the printing mechanisms in that extra length, and then dividing.
rob M.
+Meg Gamine that's a gr8 idea...! I'm trying not to sound corny but in all seriousness, that's 1 of the best concepts i've heard in a long time-- i recall a few articles on battery-tech for printed/thin batteries & printed-solar-panels: 1) Researchers Develop A Path To Liquid Solar Cells That Can Be Printed Onto Surfaces ->this might be the most amazing development as far as game-changers: i saw similar "painted solar cell" technology on a science show but don't recall who / where it was, but the Kurzweil website has this
link to USC scientists who are doing it:
2) ;
+rob Darmok :O Now you've gone and made it photosynthetic.

A machine made of these printer-cells would be versatile; repairing itself, mutating. Perhaps a skin like this, made of this solar variety, could be put over a spacecraft; or if we used a safe -- and thats the cat's bell here -- thermoelectric type we could build heart valves, organs, bones, prosthetic neural networks. Of course, they're doing this with living cells already! But how efficient is aerobic respiration? ~38% If we can transcend to a nanoscopic scale, even for just extremely specialized printer-cells, well... that would mean an awesome exactness of structure and perhaps even enhanced efficiency.
+Meg Gamine +rob Darmok Let's go way down the road you guys have been on. The features and traits you are describing as you explore possibilities all mimic what organisms do and organisms do it much more efficiently. Organisms grow photo reactive skins which help to process light into energy and they process organic matter into nutrients and fuel, they self replicate, create tools and parts, auto repair and all those other awesome things we would love to see these machines doing. So my question is where is the line? Is there one? At what point do we abandon the crude mimicry that we find in machines and start engineering organisms that can do all these things for us?
Is physical mechanics inferior to bio mechanics or is there some sort of Borg like compromise that is ultimately better than either alone?
