Hi Charly,

Of course you can just "zap out" the boring color talk, but I'll offer a quick
and partial explanation of its fascination.

The people who have been writing about "color" seem to have a wide range of
interests -
from a few with an immediate need to distinguish between the different
components of an
assembly being studied - to a few people with a long-range vision of a new
medium of
communication - true "3D printing" for use by anyone and everyone with a
special 3D

Since none of us has a functional "crystal ball" to predict the future, we can
only look at
such things as history, human tendencies, technological trends - then make a
personal prediction.
Personally, I've noted the following:

1. The market for completely new products is extremely difficult to predict.
Of course,
this does not mean that 3D printing will be wildly successful. It does,
however, make it easier to ignore dire warnings reminiscent of those which
greeted electricity, telephones, transatlantic air travel, photocopiers,
computers, laser printers, etc. [I've heard it said that the greatness of an
invention is closely related to the percentage of people who think it's
"absolutely crazy."]

2. Communication and comprehension are high priorities in today's world.
People have a particularly difficult time comprehending complex 3D issues and
have a natural
appreciation for things which can be touched, held, cut, walked around. etc.
reality" is great - but no substitute for "real reality."

3. Technology can make tremendous progress with difficult problems. When
one compares the amount of research money which has been spend on "RP" with
amount of research money which has been spent in other industries, one must
conclude that this industry is still in its "infancy." There's a lot of
progress to be made in all aspects of the 3D challenge - from data gathering
to data processing to data printing.

No problem that your budget can't handle a color machine just now. Someday,
you'll be able to stroll down the street for a colored 3D print - at your
local copy shop. You'll be surprised at the ordinary "users" you meet there.
You'll be amazed at how much this "infant industry" has grown.
