Scientists have developed a new TVAM method that uses holograms to improve 3D printing efficiency.The traditional 3D printing technique builds objects layer by layer, while TVAM uses holography and laser light to solidify liquid resin into a shape.The new method reduces energy use and increases resolution by utilizing the phase of light waves in holography.The holographic TVAM technology has the potential for a wide range of uses and paves the way for faster and more efficient 3D printing systems.
