Microstereolithography is a technique or method for fabrication of microstructures
like micromechanisms, microdevices, microchannels or microcatheters . It
comprises on axis or off axis scanning of a liquid photopolymer resin with
a focused laser beam spot and allowing the scanned portion of the resin to
cure or solidify and form the microstructures. This invention relates particularly
to a method and a scanner for three dimensional focused laser beam spot scanning
in microstereolithography for fabrication of microstructures like micromechanisms,
microdevices, microchannels or microcatheters. The method and scanner of
the invention can be also advantageously used for other applications like
laser cutting or etching, near-field scanning optical microscopy (NSOM) or
con-focal microscopy. The use areas of the method and scanner of the invention
are not, however, limited to the above applications.
