No formal education is required for a career as a 3D artist, but most prospective 3D artists refine their skills by attending specialized postsecondary art schools. Repetition and constructive feedback can improve their technical skills. Workshops and non-credit classes can help with this development. Prospective 3D artists should develop a portfolio of sample work to show prospective clients and employers. Demand for 3D artists is expected to grow slightly over the next decade, as existing artists transition to other fields.
