The idea is to take a 3D CAD model inside your PC and to have some kind
of robotic contraption build it for you in the real world.

Some examples of these machines work like this:

Anyhow - I've been wondering whether it would be possible to build some kind
of contraption that would do this using Lego (and - presumably - a significant
amount of non-Lego parts)...but all of those approaches seem to need powerful
lasers or weird chemicals or some-such.

So - does anyone have any idea what might be possible for an enthusiastic
amateur?

Wow, Steve, been a while since I've seen anything with your name on it! :)

And if you're referring to yourself there in that last sentence, I think you can
easily afford to call yourself something a lot better than an 'amateur.' ;)

As for the printer...I like that plaster idea. It's fairly simple, it requires
nothing super-unusual like high-Class lasers, and perhaps the water part could
even be done with pneumatics or some such thing. Fine motor control with very
small backlash is possible, so I don't see why not.

It would require writing some custom software, but you could probably do that,
right?

The problem is...all that plaster could get expensive.

Really neat idea though!

Marcel @ Sweden you need a glue pistol and so modified that the material it puts out can be turned of and on under extream heat. There is a coffie machine look alike that uses abs plastic.. At the moment i do not remember the machines name.. But its (...) (20 years ago, 12-Mar-04, to lugnet.robotics)
