A 3D-printing device developed by a Lawrence Livermore National Laboratory (LLNL) optical engineer has garnered a 2015 Federal Laboratory Consortium (link is external) (FLC) Far West Region Award for outstanding technology development.
The award, given for the Large Area Projection Micro Stereolithography (LAPµSL) technology, was presented to Bryan Moran at the recent FLC Far West/Mid-Continent Region meeting in San Diego.
LLNL researchers and business development executives in the Lab’s Industrial Partnerships Office have netted 26 Far West Region awards since 2007.
Started in 1974, the FLC assists the U.S. public and private sectors in utilizing technologies developed by federal government research laboratories. It is comprised of more than 250 federal government labs and research centers.
The LAPµSL is an image projection micro-stereolithography system that rapidly produces very small features over large areas, by using optical techniques to write images in parallel, as opposed to conventional techniques, which either require mechanical stages moves or the rastering of beams to expose pixels in series.

LAPµSL combines the advantages of laser-based stereolithography (that is, large area and speed, but poor resolution) and digital light processing stereolithography (that is, fine details and speed but only over a small area), enabling the rapid printing of fine details over large areas.
“The LAPµSL system is conceptually similar to building a mosaic of tiles that then combine to make a much larger picture,” Moran explained. “Each one of the tiles has a lot of detail and they go together to form the picture that, in turn, has significantly more detail.
