3D printing, also known as additive manufacturing, is a process of creating three-dimensional solid objects from a digital file. It uses an additive process, where successive layers of material are added until the entire object is created. Each of these layers is a thinly sliced horizontal cross-section of the final object.
3D printing technology has come a long way and it is now possible to print a wide range of materials, including plastics, metals, ceramics and even biological materials such as human tissue. The process can be divided into several categories such as Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), and others.
FDM is the most widely used 3D printing method, it uses a thermoplastic filament that is extruded through a heated nozzle to build the object layer by layer. SLA uses a laser to cure a photopolymer resin, creating the object layer by layer. SLS uses a laser to fuse powdered materials together to create the object.
3D printing has many advantages, including the ability to create complex geometries and shapes, the ability to produce low-volume, high-value parts, the ability to produce customized products, and the ability to make parts on demand. It has a wide range of applications in industries such as aerospace, automotive, medical, and many more.
However, 3D printing also has some limitations, such as the cost of the technology, the size of the object that can
