What is 3D printing?
3D printing refers to any manufacturing process which additively builds or forms 3D parts in layers from CAD data. The technology is significant because it offers direct manufacturing, meaning a design goes directly from you to physical product through a computer and a printer- stratasys
3-D printing is a manufacturing process that builds layers to create a three-dimensional solid object from a digital model. To print a 3-D object, the manufacturer uses a computer-aided design (CAD) program to create a digital model that gets sliced into very thin cross-sections called layers- TechTarget
3D printing is a manufacturing process through which three-dimensional (3D) solid objects are created. It enables the creation of physical 3D models of objects using a series of additive or layered development framework, where layers are laid down in succession to create a complete 3D object. 3D printing is also known as additive manufacturing- Techopedia
