Challenges:Highest Level of Precision

Highest level of precision, a challenge in fabbing resolution
To make the Fab@Home fabber more useful, we need to archieve much higher resolutions! Therefore, we need a challenge. Who can make the most precise model? The end goal is 10 micrometers or less!
Resolution as in finish quality - IE The Watch band is too rough to be used for anything but to demo the concept. Right now perhaps the only useful application is for edible cake decorations maybe?

The stated resolution of the Fabber is 25 microns and the repeatability is 100 microns, that's .025mm and .1mm respectively. That to me sounds like very good accuracy. This would lead me to believe that for better "finish" a focus should be on the build material itself and it's behavior. Does it bead up and get knobby? Does it flatten out? It seems to me that the best material behavior would be that which flattens out very slightly to meld into a previous layer or underlying surface.

--- To work toward higher resolution, we need some objective standard for measuring resolution. Some ideas are 3D scanning, such as with the David Laser Scanner Freeware, or perhaps by simply photographing the object with a reference scale. Any other ideas? Evan 10:52, 25 February 2007 (EST)

Hi, I'm a French guy, so sorry for my english. I practice by writing essay. I think that's find a better build material is the crucial point. Is it possible to see what kind of result a 2D application with fine sand or powder looks like ? Some build material for self-made candle could be used too, maybe ?
