3D printing, also known as additive manufacturing, has emerged as one of the most transformative technologies of the 21st century. It allows for the creation of complex three-dimensional objects directly from digital models, layer by layer, without the need for molds, tooling, or extensive assembly lines. From rapid prototyping to custom medical implants, aerospace parts, and even buildings, 3D printing is redefining what’s possible in design and production.

What is 3D Printing?

3D printing Market Size is a process of creating physical objects from digital designs by depositing materials layer upon layer until the object is fully formed. It contrasts with traditional subtractive manufacturing, where material is removed from a solid block through cutting or machining.

Key Process Steps:

1. Design Creation – Using CAD (Computer-Aided Design) software

2. File Preparation – Converting to STL/OBJ format and slicing into layers

3. Printing – The printer builds the object layer-by-layer

4. Post-processing – Includes cleaning, curing, or finishing the printed part
