3D printing, also known as Additive Manufacturing (AM), is a process of building 3-dimensional solid objects using different types of technologies and materials. In the automotive industry, 3D printing is commonly used to develop functional prototypes, manufacture small & complex parts of vehicles, and develop specific tools and R&D activities. Selective Laser Sintering (SLS), Fused Deposition Modeling (FDM), Electron Beam Melting (EBM), Stereolithography (SLA), and polyJet, among others, are the most popular 3D printing technologies present in the automotive industry. Polymers are the most used materials in automotive 3D printing over metals, resins, wax, and ceramics. Stratasys, Protolab, 3D Systems, Materialise, Exone, SLM Solutions, and PRODWAYS GROUP are some of the major players present in the market.
