lol that would be nice XD
That would probably take a long while to create large and complex objects, though o.o
-
That's cool, I just think it would take a while for some objects. :)
-
it can't make ANY shape though: take for instance an object where there is an appendage hanging down with no support underneath. As the printer builds up, the appendage will have nothing to rest on and fall down. i suppose that, as long as the object does not completely enclose the appendage, you could print some sort of soluble or meltable material as support and get rid of it later.
-
Build it upside-down.
-
What if you had a hollow object?
-
Build it upside-down.
what if there are 'stalactites' and stalagmites', ie, appendages on top and bottom? you'd have the same problem no matter which way you turned it
-
Turn it on its side.
Also, what the hell would look like that?
-
if the appendages are hanging out into the middle, they can only be supported from one direction: their base. if some are facing in different directions, you obviously can't accommodate them all at the same time, so turning it on it's side doesn't work. see attachment for an example: imagine it as a cross section of a semi-hollow sphere
-
That. is. Awesome. Amazing find, Sir. :)

Fab@home? Yeah, I like 3d printers. Check out makerbot.com (http://makerbot.com)
The zcorp printers are my fav, though. (search YouTube)

The next step toward making replicators and machines that produce food from cards
-
Someone made the machine make cookies.

Fab@home?
You know people, while browsing the forums, I really gotta avoid checking OmnomIRC (or #omnimaga) when loli/anime talk occurs. It makes me see weird things. In the case of this quote, I misread the word before the @ as something else. X.X
Anyway back on topic, I wonder how it handles really thin objects like a sheet of paper
-
This is an interesting idea... I remember a while back i read about a theoretical device that would allow you to build any object, with an input of all the basic elements. This looks like a step in that direction! And a very awesome one at that :P
-
Yes. The zcorp printers are powder based, which is why I like them more, but thingsblike te reprap, makerbot, and others are plastic extruders. I believe 3d printers will become more popular among people that are not hobbyists if there is simple a print button, and n problems with the print.
-
I wonder if the day where it will be possible to duplicate objects at 100% (even a calc, for example) will ever come :P
-
That would be really, really cool. Perhaps atom generation? Have a cache of hydrogen and use fusion to create new elements from them?
-
ah! to solve the issue with impossibly-shaped objects, you would have to build a printer that basically 'holds on' to the most recent layer, thus suspending it if necessary, until it pushes the next layer through. So, instead of seeing it build up from a base, you would see it lowered down as it was built
-
The way I saw the theoretical one work was that it built from the bottom and pushed the object up as it needed. Basicaly the same thing but upside down :P

That would be a very interesting idea, someone should try this.
-
I wonder how hard it would be, though x.x
-
It would be pointless. The same thing can be done with support material. So far, atomic printers have proved more elusive. A few major problems is see:
1. energy requirement
2. Elements reacting with air, or leftover chemicals inside chamber for deposition or reaction.
3. Chemical form. Eg, printing crystals.
4. Build time. Most likely days to weeks.
-
the atomic stuff kinda creeps me out, especially when you know about stuff such as Tcherbobyl x.x
Accidents and hardware/material issues can happen.
