Hi List,

This is something of a perrenial conversation. I am more convinced than ever
that the problem isn't rp, it isn't cheap rp, or 3D faxes or fabricators or
color or anything with this technology. The problem is users. They aren't there.
Technically, this is not RP's fault. Its CAD's fault. Its clumsy, highly
specialist, and overly technical. For the technology to become popular it must
have an infrastructure of CAD users. The way to get to those cad users is
through programs that are cheap, effective and cool. There are some out there. I
hope you won't get tired of me pointing out Nendo (www.nichimen.com) a $100
dollar subdivision surface modeler. Its fun. Its simple. You can make models
fast. They can be trucks and gears (NOT FOR ENGINEERING, FOR FUN), and heads and
all kinds of other things. There are a couple of others that I'm not so
impressed with--Amorpheum, www.play.com

The failure of the RP industry not to link with and influence CAD would be a
real failure indeed.

I think this one is worth at least a nickel.

Best,
michael rees
