There's no absolute 1 inch because there's always a decimal, all be it microscopic (if you measure twice) or how about you is there one or are we infinitely definable?

We're getting way off topic here so this will be my last post in this thread about absolutes. We can move it elsewhere if you want, but

In one regard you've "poisoned the well" by adding "inch" which, being a unit of measurement, is an approximation depending entirely on physical limitations - your ruler, micrometer, whatever device: your eyes; and whatever it is that you're measuring on which is subject to change, for example thermal expansion and contraction - and is simply a matter of "close enough" for whatever precision is required for specific applications. I assure you that measuring devices and relatively stable materials exist that everyone on planet Earth will agree is One Inch on any scale in which "inch" has any real meaning, but that by no means has anything limiting or inexact to do with the pristine concept of Oneness. That is not an approximation but an exact state or condition of quantity. That is an Absolute. Similarly Infinity is exact as a concept but in that case utterly impossible to even approach as a real world application or measurement.

Love 3D printers thanks for the reminder, for "once" I get time!

As for "1" http://www.linuxquestions.org/questi...43#post5704343

I'm not sure what I'd do with one but I'd still like one. A book I'm reading at the moment has 3D printed keys as plot point which could be fun.

I think that the technology is years away from maturity. The problem is going to be the plastics. Right now, we manufacture materials, be they metal, glass, or plastic, and then cut-away or grind-away "everything that doesn't look like an elephant." 3D printing, on the other hand, assembles the plastic object on-the-spot: a very different method with very different requirements. The assembled object is subject to the requirements of "a material that can be used in a 3D printer," not to its intended final use.

For instance, one of the things that was heavily promoted as being built with this technology was "a handgun." I dearly hope that no one actually fired it, or was holding it in their hand when they did, because I have no confidence yet that the construction (at the present state of the art) could handle explosive pressure-curves without exploding.

It's an interesting and promising method ... someday.

3D printing can be done with metal, too (as long as you have an industrial machine costing more than the college tuition at a private university). https://www.youtube.com/watch?v=u7ZYKMBDm4M
Everything in that gun except the springs was 3D printed using direct metal laser sintering. None of the parts in that gun were machined, though there was some hand finishing done. A Google search for 3d+metal+handgun will yield a bunch of links to the rest of the story. That particular gun passed the "1000 rounds fired" mark some time ago.

Oh, and before the legal vultures jump in, Solid Concepts does have a Federal Firearms License.

How about a printed house?
Or perhaps a new ear?

Printing guns is so yesterday.

Even NASA is investigating sending robots to Mars to print habitats before the astronauts arrive.

Very interesting stuff. I'll stick to printing with PLA for the moment.

Play Bonny!

Thank you! I thought the same as I'm sure others noticed those... was it the :eek: (as in printed buildings or cars?!)

You can also print circuit boards which cuts down on nasty chemicals like my etching compounds or even solder... eg: http://www.cadalyst.com/testing-anal...ted-pcbs-32090
tho I have seen machines that plot solder as well.

Interesting 3D printing project for the Ghost in the Shell movie.

In the movie, Major, (Scarlet Johansson) has her damaged android body repaired by 3D printing the flesh and muscles back. Now, if anybody just happens to have the .stl file to print a Scarlet Johansson...

Play Bonny!

After an episode of Futurama I have always wanted a Lucy Liu Bot...
