Latest Patents

Mahito Arai holds a patent for an "Optical formation device and method." The purpose of this invention is to provide a solid model creation apparatus that is small in size and inexpensive. The device utilizes a multiplicity of blue LEDs connected to optical fibers, with GRIN lenses arranged at the ends of the optical fibers to form an exposing head. This exposing head creates images of the end faces of the optical fibers in a photocurable resin exposure region as light spots. The diameter of a light spot is approximately 0.5 mm, while the size of a pixel within the exposure region is much smaller, around 62.5 micrometers. The optical fibers at the exposing head are arranged in a staggered matrix, allowing for precise alignment of light spots at a pitch of 62.5 micrometers in the primary scan direction. As the exposing head scans the exposure region in the secondary scan direction, all light spots can direct light onto the appropriate pixels, enabling multiple exposures to be carried out effectively.
