billybob Posted May 7, 2013 Share Posted May 7, 2013 More than likely as one of a kind items can be made. Parts can be duplicated beyond imagination. Given auto-cadcan be the launching pad. Quote Link to comment Share on other sites More sharing options...

Chris A Posted May 7, 2013 Share Posted May 7, 2013 Only size and materials seem to be the limitations now; to the uneducated. I could easily see this being used to print recorders (or "blockflutes"--wind instruments). If you've never seen a fiberglass Sousaphone bell, you'll recognize immediately the advantages of the lighter weight material. I once walked into the band hall to see the assistant band director hammering out a Sousaphone bell that was folded in half. The reason? A mistake during a close quarter drill (at TAMU) when the Sousaphone players do a 90 degree left and another 90 degree left on the next beat. One of the Sousaphone players missed the beat. It would be nice to be be able to print a new bell instead and to paint it with lacquer. The cost of buying a new bell made out of brass is very high. It could also print very good acoustic horns for loudspeaker use. For prototyping, this is like a dream world. The only real limitations now are on the cost of the printers and the hand-held 3D scanners (about $20K each or more) but you can hire these services now, reasonably.

Mallette Posted May 7, 2013 Share Posted May 7, 2013 Make no mistake about it. These aren't simple continuations of other technologies like the inkjet printer or the cell phone. These are gen 1 replicators and their descendents will be part of a whole new world. The industrial revolution took the means of production from the cottage and into vast factories. We're coming full circle, friends. Medical scientists recently used one to print a rat heart. It worked. Consider the implcations...

Daddy Dee Posted May 7, 2013 Share Posted May 7, 2013 printing horns would be nice. haven't been able to grasp what the price would be. part of the 3D printing energy is about producing, or reproducing something that otherwise would be unavailable. That's pretty cool. and quite a few of these projects are conceivably worth alot more than they cost. for example, what would a ballpark cost be of printing say, a K-403 horn? if anyone could help me with the process, i'd appreciate that. i can understand drawing an object in CAD and sending that to the 3D Printer. can also imagine designing a tractrix horn in the software and sending that to the printer to be fabricated. I've seen a pic of Klipsch's 3D printer. Having it would have to be an asset to all manner of design projects. to replicate something like an HF horn, the "document" would have to include a scan of the object, right? How would this be done? Laser something or other, i imagine. but what? Quote Link to comment Share on other sites More sharing options...
Mallette Posted May 7, 2013 Share Posted May 7, 2013 Dee, this technology is in its infancy. While the successful firing of a gun printed is a major "Shot heard around the world," we've a ways to go before we're making large objects in the garage. One stage will be cheap ones where the money is made on the materials...just like inkjet printers. However, this will not last as the print heads and such can't be rigged like the inkjet printers are to require a certain kind of ink. As competition increases, more materials will be available for special needs and the capabilities will increase. I do see, in the next few years, job shops with larger devices where you can take your pattern files to be produced. However, many things will remain cheaper from the production line and these shops will serve mainly "one offs" for a while. As to the laser scanning in 3D, that's a technology that's been around quite a while. Since relatively few needed it, it's remained expensive. With increased demand, it will come down as well. While no expert, I think the Lytra technology...already cheap...may be a candidate for this job. Dave Quote Link to comment Share on other sites More sharing options...

Just tie your hair up in a bunch like a pigtail but pull it up directly on top of your head like Pebbles. Pull it tighter for how many years younger you want to appear.My GF is jealous cause she thinks I am looking to replace her with a 3D image. I told her it was not possible...yet. Little white lie.

oscarsear Posted May 7, 2013 Share Posted May 7, 2013 Medical 3-d scanners can download to these units. They've been used in forensic skeletal reproductions. There's a company in Japan selling a service offering a 3-d model of your baby - as an as yet unborn fetus. They might find medical applications in radio tagging tumor cells and 3-d modeling the full extent of a malignancy to ascertain treatment approaches or efficacy. And on the quantum scales these devices can produce some really small parts for really small machines. Quote Link to comment Share on other sites More sharing options...
billybob Posted May 7, 2013 Share Posted May 7, 2013 We may see 3D printing in a viable enterprise as a veritable panacea. First heard on the BBC radio, The applications are yet to be exploited. The neighborhood photo copy shop side by side with the 3D store. The miniature dupliction sounds exciting and full of possibilities in the health/medical field, as you have pointed out. IMHO From what you say, this can be an economic device to help fix the economies, if done with forethought in mind. For instance, if one were to eliminate or even, incapacitate a man job, then what is the point. Rhetorical) Medical 3-d scanners can download to these units.

mustang guy Posted May 8, 2013 Share Posted May 8, 2013 That is so cool, Boxx! I just looked, and you can buy home 3D printers for $1,300. http://cubify.com/cube/compare.aspx?tb_cube_compare Cartriges are $49 for one, and according to the website the cartridges are filled with "our custom ABS plastic, or PLA Plastic, with 16 color options, and are designed to work with the Cube, each one containing enough material to make about 35 models per cartridge. Switching them out is a breeze - they snap right in. The Cube can also tell you how much material you have left, and won't let you start to print a creation if you don't have enough material to finish it, to avoid waste. You can print about 13 to 15 cell phone cases (or creations of similar size) from a single cartridge." That is not too bad! Quote Link to comment Share on other sites More sharing options...
mustang guy Posted May 8, 2013 Share Posted May 8, 2013 This is gonna be revolutionary: 3D Printing Graphene... 3D products made from graphene and textiles made from carbon nano-tubes are gonna be big! I wonder how the 3D printer will create the molecular bond... In labs, they can create 2D graphene with a simple DVD burner. Quote Link to comment Share on other sites More sharing options...
mark1101 Posted May 8, 2013 Share Posted May 8, 2013 We have been using similar technology for years to create prototype models of small products and enclosures (so have many other companies). They always came out brittle and I never considered these to have any real function. It's a 3D version but it's like a stone.........you can look at it, but it won't function like the real thing. This technology may be different and slightly better, but I doubt it's anything revolutionary.............I can't watch the video from here due to our security.

Chris A Posted May 8, 2013 Share Posted May 8, 2013 This is exactly what I would do if I were in Tom D's shoes--this 3D printing technology is tailor made for prototyping and test (if you can get a 3-D printer that can handle the size). After the design is proved out through testing, then the rate manufacturing molds can be created, since these are typically expensive but last for many thousands of produced parts before they wear out. Tom Danley is a very good engineer. He does one more thing that is very rare: he freely shares his designs which is pretty spectacular, IMHO. I wish that I could hear one of these multiple tap horns, since there seems to be a lot of positive reviews on it. I haven't seen any of the audiophile mags test one, however (e.g., the SH-60 or one of his newer designs). There seems to be a lot of anti-commercial-eqt. bias and anti-horn bias among those magazine "experts". It's a shame since I believe Danley is doing essentially the same thing that PWK did in the 40s, 50s, and 60s: improving the state of the art and designing new loudspeakers that are qualitatively different. The newest DSP techniques to produce inverse digital filters that can filter out undesirable horn and driver transient performance is also very interesting, but in that particular area, the engineer(s) involved are clamping down on releasing their work such that no one can see what they are doing. C'est la guerre! Chris Quote Link to comment Share on other sites More sharing options...
Marvel Posted May 8, 2013 Share Posted May 8, 2013 Siemens is working on a 3D printer that uses metal, to manufacture/prototype more durable items. For sure, they have the money to invest. Bruce Quote Link to comment Share on other sites More sharing options...
mark1101 Posted May 8, 2013 Share Posted May 8, 2013 The technology I was referring to is stereo lithography. You put a block of material into the machine and a laser cuts a 3D version of the target sometimes overnight. I suppose you could take a K402 horn and recreate another using this technology. There is only one problem. The injection molded K402 that Klipsch produces probably costs Klipsch about $12-15 each. The stereo lithography version would cost about $4-5K each, since it is a prototyping tool and not a production tool. You'd be better off inviting Tom Danley to the superbowl in exchange for one of his horns. Quote Link to comment Share on other sites More sharing options...

You can go down to a 3D printing shop and have them run it out for you using a thumb drive for your data files, or alternatively, you can put one 3D printer in your existing reproduction graphics department area. The materials used are less "nasty" than SLA, IMHE. Chris Quote Link to comment Share on other sites More sharing options...
