Dear Elaine,
also with the MPL technology (first published in
1998 i think, they are using a projector) lighning of
one layer is possible (information about MPL via Deltamed,
Mr. Moch, deltamed@t-online.de)
and with our RMPD-MASK technology
(discribed serval times) its also possilbe to
make the whole layer within one lightning
(no dot by dot scanning like in classical RMPD).
On Hannover Industrie Fair in Hannover 2001
we will again show some serial micro-products made
with this technology.
With RMPD-NANOFACE surface finish in sub-nanometer
range is possible.
www.microtec-d.com/news.htm shows example.
Best regards
Andrea Reinhardt

Microstereolithography: A new process to build complex 3D objects
Author Beluze, Laurence. Bertsch, Arnaud. Renaud, Philippe.
Source Proceedings of Spie - the International Society for Optical
Engineering. v 3680 n II 1999. p 808-817.
Abstract In this paper, a new microstereolithography apparatus is
described. It is an integral process in which a complete layer can be
made
in one exposure only, in contrast to vector-by-vector
processes which are based on the vectorial tracing of each layer. As
for
most microstereolithography processes, complex objects can be realized
by
superimposing layers, each layer being obtained by a
light-induced polymerization of a liquid resin. The vertical and
transverse
resolution of the process we are developping have been measured.
Complex in
shape objects have been realized: small 3D
polymer components have been built such as turbines, microsprings, or
micropipes. They are composed of a large number of layers with a
resolution
better than 5 mu m in the 3 directions of space. Some
of these objects serve to demonstrate that complex in shape 3D objects
can
be manufactured with this technology. Sample structures which can be
used
in microfluidics, microrobotics or in the biomedical
field are presented.
