Volumetric Additive Manufacturing (VAM) is a new additive manufacturing (AM) technology. As a layer less manufacturing technique, VAM offers faster printing speeds, no support requirements, and greater design freedom compared to traditional AM. In recent years, VAM has made significant progress in printing equipment improvements and material diversity. This article reviews the technological development of VAM from three perspectives: equipment, manufacturing processes, and materials. It evaluates and analyzes the status of each dimension and compares the technologies and research results in each. VAM's printing equipment and manufacturing processes have been improved in terms of exposure mechanisms and light projection efficiency, resulting in the development of automated exposure AM and full-scale tomography volumetric AM. Regarding printing materials, more biomedical materials are now being used in VAM, and VAM technology can process living cells and cell-laden materials. These advancements not only demonstrate the immense potential of VAM in revolutionizing manufacturing paradigms but also open up new possibilities for applications in regenerative medicine and personalized healthcare.
