WebStereolithography is one of the most widely used 3D printing technologies. Its impeccable surface quality, ability to produce fine details, and wide selection of materials make it ideal for high-quality visual models and prototypes, complex aesthetic parts, and masters for techniques like vacuum casting and lost wax casting. Web2.1Lithography Approximation Model The Hopkins di raction model [5] is well accepted in literature to represent lithography behavior. However, computing the model is extremely time consum-ing. To reduce the compute overhead, a singular value decomposition (SVD) approximation is typically adopted for lithography modeling. The basic idea is fishguard street map
