Raster‐based exposure through multiple parallel beams in stereolithography

Kai Loose, Toshiki Niino, Takeo Nakagawa

A method to control raster‐based exposure in multiple‐LED photographic curing (MPC) is introduced. During the build process, beams of multiple sources, each exposing a separate…

Mechanical characteristics of fiber‐filled photo‐polymer used in stereolithography

C.M. Cheah, J.Y.H. Fuh, A.Y.C. Nee, L. Lu

The effects of the addition of short glass fibers into an acrylic‐based photo‐polymer (De Solite SCR310) used in the laser solidification process have been studied. Comparisons of…

Reaction heat effects on initial linear shrinkage and deformation in stereolithography

Hiroyuki Narahara, Fumiki Tanaka, Takeshi Kishinami, Satoru Igarashi, Katsumasa Saito

In the industrial use of stereolithography, precision is always a problem. The basic phenomenon of solidification shrinkage has not been sufficiently investigated. This study aims…

Calibration of shrinkage and beam offset in SLS process

Xiangwei Wang

Selective laser sintering (SLS) is one of the most successful rapid tooling processes. Shrinkage and beam offset are the two most important control parameters in this process…

Rapid tooling for sand casting using laminated object manufacturing process

Wanlong Wang, James G. Conley, Henry W. Stoll

It is now possible to generate tooling for near net shape manufacturing processes directly from a CAD database by using computer numerical control (CNC) machining or a variety of…
