3D printing is a process of developing a three-dimensional solid object from a digital model by successively adding material in layers. The process is also known as additive manufacturing. In 3D printing, the material is usually laid down in a controlled manner to build up the final object, unlike traditional manufacturing methods such as machining or molding where the material is removed to create the desired shape.
There are various technologies and materials used in 3D printing, including fused deposition modeling (FDM), stereolithography (SLA), and selective laser sintering (SLS). 3D printing has many potential applications in product design, rapid prototyping, custom manufacturing, architecture, healthcare, and more. It has great potential to transform the way products are made and bring about new levels of customization and accessibility.
