Volumetric printing is an additive manufacturing technique that solidifies an entire 3D object within a resin vat using tomographic light projections.
Reduces time and complexity in 3D printing by eliminating the need for layer-wise fabrication, enabling faster prototyping and potential improvements in bio-printing applications.
The process involves focusing light beams from multiple angles to trigger polymerization across the volume of the material, creating a complete 3D object instantaneously without layer-by-layer construction.
Manufacturing involves precise optical systems to project light beams from multiple angles into a resin vat. The technology requires high-precision components such as multi-axis mirrors or DLP projectors.
The build process starts with defining the object using CAD software, then projecting light through a lens system that splits and focuses the beam across various angles to solidify the entire volume of material at once.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking required for certain resins. Overall energy consumption is lower compared to layer-by-layer techniques but higher than some other additive methods.
