One notable exception is volumetric 3D printing, where entire structures can be generated in a single process without the reliance on layer-by-layer construction. It should be highlighted, however, that volumetric technology is predominantly in the research stage at present.
In contrast to subtractive manufacturing, which involves carving or hollowing out material from a solid block using tools like milling machines, 3D printing allows for the creation of intricate shapes with reduced material usage compared to conventional manufacturing techniques.
