3D printing

3D Printing (Additive Manufacturing) is the digital process of constructing three-dimensional objects by adding material layer-by-layer: it's manufacturing on demand.

This technology is a paradigm shift from subtractive methods, building complex geometries directly from a CAD file. Key processes include Fused Deposition Modeling (FDM) for plastics like PLA and ABS, and Selective Laser Sintering (SLS) for high-performance polymers or metal powders. Applications are diverse and high-value: rapid prototyping reduces iteration cycles from weeks to days, while end-use parts (e.g., custom medical implants, specialized aerospace components) are now common. The industry is projected to reach an $84 billion valuation by 2029, driven by material advancements and industrial-scale adoption (Source 4).
