The holograms are generated using a technique ... This self-healing property is essential for 3D printing with bio-resins and hydrogels that are loaded with cells, making the method ideally ...

Additionally, by controlling the individual beam powers as the print progressed, up to eleven grey-scale values could be generated, allowing variable material properties to be realized. Holograms ...

(Nanowerk News) While traditional 3D printers work by depositing layers of material, tomographic volumetric additive manufacturing (TVAM) involves shining laser light at a rotating vial of resin until ...
