We propose a method for the construction of particle models with realistic structure group SU(3) ⊗ SU(2) ⊗ U(1) and particle content on a noncommutative space based on generalized Seiberg-Witten maps. The construction solves previous problems with charge quantization and choice of gauge group. Many new interactions that are absent in the Standard Model on commutative space time are predicted.
