Additive manufacturing starts with a digital 3D model of the object to be produced. The model can be created using computer-aided design (CAD) software or obtained from 3D scanning techniques. The digital model is then sliced into thin cross-sectional layers, which serve as instructions for the 3D printer.

The 3D printer builds the object layer by layer, following the instructions from the sliced model. Each layer is typically a thin cross-section of the final object, ranging from fractions of a millimeter to several millimeters in thickness, depending on the chosen printing technology.

There are various additive manufacturing technologies available, each with its own specific process and materials. Some common 3D printing technologies include:

1. Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF): This technology melts and extrudes thermoplastic filament through a nozzle, which moves in a controlled manner to deposit the material layer by layer.

2. Stereolithography (SLA): SLA uses a liquid photopolymer resin that is hardened by a light source, such as a laser or UV projector. The object is built by selectively curing the resin layer by layer.

3. Selective Laser Sintering (SLS): SLS employs a high-powered laser to selectively fuse powder materials, typically polymers or metals, layer by layer, creating solid objects.

4. Direct Metal Laser Sintering (DMLS) or Selective Laser Melting (SLM): These technologies use a high-powered laser to selectively fuse metal powder particles, layer by layer, to create metal objects with high precision.
