How 3D Printing Works
At its core, 3D printing is a process that builds objects layer by layer, guided by digital files. This additive manufacturing process is what sets 3D printing apart from traditional subtractive manufacturing methods.
The Basic Process of Additive Manufacturing
The fundamental process of additive manufacturing involves the 3D printer adding material layer by layer to build an object. This process is regulated by a computer-aided design (CAD) software or 3D modeling software that ensures precision and exactness.
The 3D printing starts with a digital file that contains the design specifications of the object to be printed.
From Digital File to Physical Object
The journey from a digital file to a physical object involves several critical steps. First, the digital model is prepared using 3D modeling software. This model is then sliced into layers by slicing software, which generates a G-code file that the 3D printer can understand.
The 3D printer interprets this G-code and begins the process of depositing or solidifying material according to the specifications.
Layer-by-Layer Creation
The layer-by-layer creation is the hallmark of 3D printing. The 3D printer deposits material, such as filament or resin, layer by layer, following the instructions from the G-code file. The height of each layer can significantly affect the print quality and the overall printing time.
Support structures are often necessary to prevent the object from collapsing or deforming during the printing process.
