This technique was invented by Charles Hull in 1984 and consists of using an ultraviolet laser beam to cure a photo polymer, that is, stiff a polymer light-sensitive. A platform submerged in a reservoir is capable of moving vertically and the UV ray is drawn on a thin layer, the build section. The tour hardens into solid materials. Below the lower platform, leaving another layer to the next section.
Tissue engineering is one of the areas of further research into applications of stereolithography, as the latter allows a good control of the resolution and geometry of the systems required for reproductive tissue and cell culture, commonly known as schaffolds (a word that refers to scaffolds where cells can be grown).
