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.
