Abstract:
1. A method for making a three-dimensional structure fabricated by microstereolithography, said method comprising steps of: forming said structure from a photo-curing material selected from a group consisting of acrylate, epoxy, acrylate-epoxy complex, and oxetane; detoxifying said structure sufficiently that it is possible to culture cells on a surface of and in contact with said structure; said detoxifying is achieved by heating said structure to at least its glass transition temperature after UV-curing, wherein one of dimensions x, y, and z of at least one portion of said structure is less than 1 mm; the method further comprising the step of deforming the structure due to its own weight by reducing its size according to size effect when the structure is heated above its glass transition temperature.
