Based on the two-photon polymerization technique, an analysis of product shapes is performed so that their digital manufacturing models can be efficiently processed for micromanufacture. To describe microstructures, this analysis shows that nonmanifold models are of interest. These models can be intuitively understood as combinations of wires, surfaces, and volumes. Minimum acceptable wall thickness, wire di,nension, and laser density of energy are among the elements justying this category of models. Taking into account this requirement, a model preparation and processing scheme is proposed that widens the laser beam trajectories with a concept of extended layer manufacturing technique. A tessellation process suited for non-man Void models has been developed for computer-aided design models imported from standard for the exchange of product files. After tessellation, several polyhedral subdomains form a nonman Void polyhedron. To plan the trajectories of the laser beam, adaptive slicing and global 3D hatching processes as well as a "welding" process (for joining subdomains of different dimensionality) have been combined. Finally, two non,nan Void microstructures are fabricated according to the proposed model preparation and processing scheme.
