RP&M show

Hi folks,

    I promised to share my thoughts on the RP&M show with Karl, Roger, Glenn
and the other folks who could not make it.

    I think this was a very exciting show for several reasons:

        -- Objet was there with their new machine, a very slick looking baby
that was shown making some pretty intricate geometries, including mechanisms
with moving parts. It works by ink-jetting photopolymer, ironically a sort
of cross between an SLA and a ThermoJet. The items were a little gummy
straight out of the machine. Some people said they noticed an acrylate odor
around the booth, but I didn't.

        -- Z was making color objects by putting different colors in their
binder jets, a sort of obvious improvement, nicely implemented. In all the
models they were showing off, each color was used individually, but they
also showed me a sample of an early attempt to print a still-life painting
using 4-color process mixing of colors. It was interesting how little
interest the use of color seemed to attract from show-goers, but I predict
this capability will grow on the market and a few years from now you will
not be able to sell a monochrome fabber at all.

        -- Two companies were presenting Web-based RfQ (request for quote)
systems for fabbing services, www.Bits2Parts.com and www.ProtoMarket.com.
Bits2Parts is part of a suite of Web tools being developed under the
PlanetCAD umbrella by Spatial Technologies, developers of the popular ACIS
CAD kernel. ProtoMarket is from an entrepreneurial start-up. These Web-based
fabbing portals are a very exciting development for the industry, beginning
the creation of the important connection between fabbing and the Internet.

        -- POM was exhibiting objects made by the direct metal process
developed by Jhodi Mazumder at the U of Michigan. Its an interesting process
that seems to achieve high metallic density without generating high
temperatures in the workpiece, a neat trick.

    There was other cool stuff too, but these were some of what I found the
most exciting. The digital manufacturing revolution is heating up, even
though most of the world still has no idea that we are here!
