You came close to contradicting yourself here. I suspect that even cheap generic project boxes are likely to cost more at retail than the $0.75 you apparently spent to make it yourself. As you noted, the quality probably wasn't as good; but we can always hope that "The Innovator's Dilemma" scenario will take care of that for us. And it should be noted that being able to have a precise custom made object may have its own value. If for no other reason than convenience, I believe that 3D printing will start to take off once it can provide reasonably equivalent quality for about the same price as the object could be obtained in a regular retail environment. All the stupid plastic parts that go into appliances, toys, cars, etc. which either are impossible to find or are outrageously priced are ripe for this. It will be interesting to see how manufacturers adapt. Will they try to try to introduce the equivalent of torx bits to make it impossible to fix anything without authorization? Or will they instead embrace the change by perhaps making the needed 3D design files available and stop making/selling spare parts entirely? Life might be easier for them, if they could tweak their design whenever they liked and not have to worry about making/stocking spare parts for all of the variants.

This is true for things for which mass production demand exists. Bespoke and niche products will never have that demand and will never benefit from scaling up production. For these, the rapid prototyping and small scale production turnaround benefits are huge. Some examples: Mr. Speakers, who some of you may know as a cottage market modder of Fostex headphones, now makes his own headphones using 3D printed cups. McLaren are using 3D printed components on their F-1 cars this season. The turnaround times for parts manufactured this way are measured in days compared to weeks for traditional methods. In medicine, one-off printed models of patients' organs have been of help in diagnosis of illnesses and training new doctors, and the idea of bespoke implants holds amazing potential. -- Rich P. ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
Re: [Discuss] 3D Printers
I've had the 3D printer working for about a week now, I have to say its interesting. Some of my friends at work and I have been thinking about this.. Are they a fad or a technology with a big future? I'm still not sure. Yes, they can make a lot of things, but the pieces will never be cheaper than mass production. They will probably never have the "quality" of a molded plastic. Then there is "plastic," metal would be nice. So assuming plastic only.That has a wide range of application, so maybe that's enough? One thing I did print was a Raspberry PI project box. it only took 4% of a 1kg roll of filament. The filament was on sale at Microcenter for $14.99. The box cost about $0.60 in materials, and maybe 5~10 cents of electricity. It 10 hours to print. About 5 hours for the top and the bottom. I also printed a camera holder for the Raspberry PI camera, probably $0.05 worth of filament. So, it may make sense for people like me who like to build things. > I recently bought an ANet A8 3D printer for 163.99 (a week ago counting > shipping) > > www.gearbest.com/3d-printers-3d-printer-kits/pp_343643.html?currency=USD&viphttp://www.gearbest.com/3d-printers-3d-printer-kits/pp_343643.html?currency=USD&vip=760163&gclid=CJLTpfywoNMCFduEswoddZsDaw=760163&gclid=CJLTpfywoNMCFduEswoddZsDaw > > I am currently printing stuff right now.

Re: [Discuss] 3D Printers
One of my former coworkers bought a Lulzbot 3D printer, and Lulzbot donated a 3D printer that we could set up in a lab at work. Lots of rotating gears and robots.
