Abstract
The purpose of the invention is to provide a solid model creation apparatus that is small in size and inexpensive. A multiplicity of blue LEDs are prepared, optical fibers are connected thereto, and GRIN lenses are arranged at the ends of the tips of the respective optical fibers to constitute an exposing head,The exposing head,forms images of the end faces of the respective optical fibers in a photocurable resin exposure region,as light spots,The diameter of a light spot,is, for example, 0.5 mm, but the size of a pixel,within the exposure region,is much smaller; for example, 62.5&mgr;. The multiplicity of optical fibers at the exposing head,are arrayed in a matrix such that they are displaced in staggered fashion so that respective light spots,are lined up at the pitch 62.5&mgr; of the pixels,in the primary scan (Y-axis) direction. As the exposing head,scans the exposure region,in the secondary scan (X-axis) direction, all of the light spots capable of directing light onto appropriate pixels, these being the respective pixels,to be cured within the exposure region,are turned on and multiple exposure is carried out.
