Very interesting and a great job gathering and posting the page. Despite
all of the examples the you have found I believe that my comments are valid.
As much as I love the RP industry I could never with a clear conches sell
the processes as "Rapid Manufacturing" or "Direct Manufacturing". There are
still way too many stumbling blocks to overcome: accuracy, consistency,
speed, repeatability, limits on feature size....Just to name a few!

Subject: Review of direct manufacturing threads
One of the hottest topics of discussion on the RP-ML in 1999 was
of fabbers ("rapid prototyping") for direct manufacturing, not just
prototypes. The two major threads on this subject have been
together and posted on Ennex.com at
In August 1999, an engineering student by the name of Sean
his first posting to the RP-ML, not knowing what a debate his
about to launch. Sean described a project in which he was planning
compare the cost of making a machine part directly in a fabber
it by "traditional" means. He asked the list if anyone else had ever
into this before. A number of people responded who had indeed spent
deal of time either thinking about or actually doing direct
Then, in November, veteran RP-ML correspondent Elaine Hunt
inquiry asking who on the list had produced "a model that was the
product" and what kind of results they got. Again, there were a good
of informative responses.
Please take a look at this new page. It makes for some
reading. If people want to make any additional comments on those
I'll add them to the page.
