Definition - What does 3D Printer mean?
A 3D printer is a type of material design printer that designs and builds 3D models and products of devices and components using an additive manufacturing process.
3D printers design three-dimensional prototypes and create the end product by directly building them using computer aided design (CAD) or software-created 3D design diagrams, figures and patterns.
3D printers may also be called additive manufacturing printers or fabrication printers.
Techopedia explains 3D Printer
3D printers are primarily used to build and enable rapid prototyping of three-dimensional objects and structures using direct source files from a 3-D designing application such as AutoCAD. 3D printers employ additive manufacturing, where the printer designs the object by applying sequential layers of raw material to actually print a three-dimensional object.
3D printers eliminate the need for further machining or subtracting processes such as cutting and grinding; the final product is built in three dimensions without waste.
