Fused Deposition Modeling (FDM) is a 3D printing procedure that utilizes a constant fiber of a thermoplastic material. Filament is encouraged from an expansive curl through a moving, warmed printer extruder head, and is stored on the developing work.

LASER sintering and melting refer to a laser based 3D printing process that works with powdered materials. The laser is traced across a powder bed of tightly compacted powdered material, according to the 3D data fed to the machine, in the X-Y axes. As the laser interacts with the surface of the powdered material it sinters, or fuses, the particles to each other forming a solid.

Stereolithography is an added substance fabricating process that, in its most basic structure, works by centering a bright (UV) laser on to a tank of photopolymer resin.

Direct Metal Laser Sintering (DMLS) is a direct metal laser melting (DMLM) or laser powder bed fusion (LPBF) technology that accurately forms complex geometries not possible with other metal manufacturing methods.

3D scanning is a technique used to capture the shape of an object using a 3D scanner. The result is a 3D file of the object which can be saved, edited, and even 3D printed. Many different 3D scanning technologies exist to 3D scan objects, environments, and people. Each 3D scanning technology comes with its own limitations, advantages, and costs. 3D scanning technologies can be classified in categories:

• Laser triangulation 3D scanning technology

• Structured light 3D scanning technology

• Photogrammetry,

• Contact-based 3D scanning technology

• Laser pulse
