Volumetric Tomography is an advanced additive manufacturing technique that enables the rapid creation of three-dimensional objects by selectively curing photopolymer resin within a volume using precise light projections.
Traditional additive manufacturing methods are slow due to their layer-by-layer approach, which limits speed and complexity of the objects that can be produced. Volumetric Tomography addresses these limitations by offering faster production rates and greater design flexibility.
The process involves projecting intersecting light beams into a container filled with liquid photopolymer resin. The intersections of these light beams act as focal points where the resin rapidly solidifies, forming the desired object in a single step without the need for layer-by-layer printing. This method significantly reduces print times and can produce highly complex geometries.
The technology requires specialized equipment for light projection and resin handling. The process is highly automated but still benefits from precise control systems to ensure accurate curing patterns.
A container filled with photopolymer resin is placed in a machine that projects intersecting laser beams or other light sources into the volume of resin. The light causes the resin to solidify at specific points, forming the object layer by layer until completion.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and resin curing processes.
