Method and apparatus for printing raster lines in a selective deposition modelling system

摘要

Techniques for printing raster lines in a selective deposition modeling (SDM) system. Raster lines may be printed using different numbers of jets in each group in different passes. Moreover, full and partial head randomization is available. Selected raster lines are printed in one direction, although the print head prints in two directions. Furthermore, raster lines printing may be interlaced, and deposition order may be changed between layers.
