Abstract Multiple LED Photographic Curing (MPC) has proven capable of drawing cross-sections of three-dimensional objects like printing a sheet of paper. Using raster scanning, however, simultaneously exposing a photopolymer with 1024 beams of light involves various unknown issues. The aim of this research work was to examine the formation of individual strings and the connecting mechanisms between strings and layers. At light power ranging from 19.0 to 30.3 mW and at various scanning speeds, string formation perpendicular to scanning direction differs greatly from that in scanning direction. Planar curing of layers happens by curing strings side-by-side with a constant spacing of 62.5 microns. (Auth abstract) [References: 7]
