The Definition Of 3D Printing

3D printing is the process of creating objects layer by layer using computer-aided design (CAD).3D printing is commonly used in the manufacturing and automotive industries, where 3D printers are used to make tools and parts.

3D printing uses computer-aided design to create three-dimensional objects through a layered approach. 3D printing, sometimes called additive manufacturing, involves layering materials such as plastics, composites or biomaterials to create objects that vary in shape, size, hardness and color.

Definition and Types of 3D Printers

Definition:

In other words, 3D printers use CAD to create 3D objects from various materials such as molten plastic or powder. 3D printers come in many shapes and sizes, from devices that sit on a table to large architectural models used to build 3D printed homes. There are three main types of 3D printers, each of which uses slightly different methods.

Types:

•Stereolithography or SLA printers are equipped with lasers that shape liquid resin into plastic.

•Selective laser sintering, or SLS printers, use a laser to sinter polymer powder particles into an already strong structure.

•Fused deposition modeling or FDM printers are the most common. These printers release thermoplastic filaments that melt through hot nozzles, forming objects layer by layer.
