Based on controlling the minimum energy state of the interface between a curable optical liquid and an immersion liquid and dictating a geometrical boundary constraint a team of researchers in Israel has developed a method to shape liquid volumes and solidify them into desired freeform components. They provided an analytical solution for the resulting topography given a predefined boundary and demonstrated the fabrication of freeform components with sub-nanometer surface roughness within minutes. The process allows for rapid prototyping of high-quality components, has the potential to answer an unmet need in the optical design industry and allowing researchers and engineers to rapidly test freeform design concepts… read more.
