What is 3D Printing and How Does It Work?
At its core, 3D printing is the process of creating three-dimensional objects from a digital design. This is accomplished by layering materials—plastics, metals, or even living cells—based on a Computer-Aided Design (CAD) model. The essence of 3D printing lies in its ability to produce items quickly and efficiently, reducing waste and expediting the prototyping process. The typical workflow begins with the creation of a digital model, followed by translating this model into a format suitable for 3D printing, often utilizing slicing software to make the design printer-ready.
