During 3D printing, the layers separate as the printer nozzle deposits the material layer by layer, following the design specified in the digital model. The printer builds the object from the bottom up, with each layer fusing to the previous one as it cools. This process allows for the creation of complex and intricate shapes, as the layers gradually build upon each other to form the final 3D object. **
