Scientists develop DISH volumetric 3D printing method using rotating periscope and holographic light fields; prints millimeter-scale objects at 19-micron resolution in 0.6 seconds without sample rotation, enabling mass production.

Sub-second volumetric 3D printing by synthesis of holographic light fields

MainPrecise and efficient manufacturing of complex 3D structures is increasingly vital across diverse fields such as structural mechanics3,4,5, photonics6, pharmaceutics7, tissue engineering8,9 and drug screening10. Traditional methods such as moulding11 and phase separation12 are efficient for mass production but prove costly and time-consuming when modifying structures. 3D printing methods such as stereolithography13, digital light processing14,15,16 and two-photon polymerization17,18,19 offer...
