3d printing

[justin ball]

Can you scan and print a disk or cylinder with a 3d printer? Can you print a new one designed by 3d software?

Someone did print a record, however it has no high frequency response at all and is mono, and you can hear the sound of the printer as it printed the record. Maybe in a few years! I get much wider response than this with my Edison studio recorder. As usual, I hear no cymbal or sibilants, on the 3d printed records !

Nope. The commonly available consumer "3D printing"
technology which is currently being endlessly hyped
up nowadays is only sufficient for making rough copies
in plastic of things which do not require any sort of super-fine detail.

This "technology" in my humble opinion is following
a very similar path to other things promised in the
past such as:

1) Flying cars.
2) Picture phones.
3) Personal robots to clean your house.

Not quite ready for prime time.....
Hype it up though.
(can you say "dual airbags" ?)

I went to a "makers lab" in North Vancouver a few years ago and their machine could do detail, but not DETAIL, like what might be in the grooves. But then again, theirs was $100,000, not $500. And it was the powder, not the grass strimmer string.

I reckon a few years from now it should be possible, maybe, could be, I think...

I went and looked at a few more videos, and the biggest problem I s is that they are using a 33rpm record needle with a groove BIGGER than a 78. What happens if you use a needle that fits? Or play it quickly so lots of information is spewed out?

3D printers don't have the resolution needed to print the vibrations in the grooves. They can print a record, but you will not here much, if anything but noise. The higher resolution printers are good to .002 - .001 inches. To print the vibrations in the groove you would need a resolution to .0001 or better. Even then the materials that would be printed, typical ABS, and and layer pattern from the printing would not have the durability and still not allow for a clean record.

Even if you could print to that resolution the cost would be prohibitive. his would be a 6 to 10 hour print at a cost of $300/hr (estimated because a printer like this doesn't exist.)

Sorry.... Nice in theory, but.....

Hope this helps with the explanation....

I really hope you're wrong, Chuck. Although the average-street-driver crossing the skies overhead is mostly a nightmare than a technological dream, a way to easily produce spare parts in very low batches (perhaps single pieces) is very deeply felt in all hobbies in which repairing no longer supported items is part of the deal. And although we will possibly never see a robot cleaning our house, 3D printing is already pretty well set-up and diffused. Even in Italy there are shops that will print your prototype at affordable prices, if you provide a CAD file or a 3D scan of what you need.

One funny application that I recently saw was made by a group of folks, who play with slot cars, who CAD designed track parts that offical makes never produced or refuse to produce (like brand-to-brand adapters or special curve radiuses). Funny and very promising.

(Picture phones are in almost everybody's hands in Europe since at least half decade).

Ferrari currently use 3D printing to produce prototype and scaled parts for wind tunnel analysis for their Formula One program. Almost all the teams are using 3d printers to some degree for prototypes.

I also read somewhere that some of the trophies are made using the technology, but I don't think they're for F1.

A friend and I were going to build a printer several years ago. It's currently sitting at number 279 on my list of things to do.

The technology will eventually develop to that point and beyond. It's still in its infancy with a great deal of refinement yet to be done.
