3D MFG / manufacturing, also known as additive manufacturing, is the process of creating three-dimensional objects through successive layers of material being deposited or fused together. This process contrasts with traditional manufacturing, which typically involves cutting away material (subtractive manufacturing) or molding it into shape.

Key aspects of 3D manufacturing include:
1 - Additive Process: Objects are built layer by layer, with each layer fusing to the one below it., the workpiece rotate 2 - Materials: Various materials can be used, including plastics, metals, ceramics, and even food or biological substances. Some common materials include:
A. Plastics: PLA, ABS, Nylon
B. Metals: Titanium, Stainless Steel
C. Composites: Carbon fiber-infused materials

Techniques:
A. Fused Deposition Modeling (FDM): Material is heated and extruded layer by layer.
B. Stereolithography (SLA): Uses ultraviolet lasers to cure liquid resin into solid layers.
C. Selective Laser Sintering (SLS): Uses lasers to fuse powdered material (like metal or plastic) into solid objects.
