Over the past few decades, 3D printing, sometimes referred to as additive manufacturing, has revolutionized numerous sectors. It is a method of building three-dimensional items out of material one layer at a time using a digital model as a guide. This approach provides unmatched adaptability and has the potential to challenge established production procedures.
Background on 3D printing
Chuck Hull's invention of stereolithography, a method that served as the basis for contemporary 3D printing, in the 1980s is credited with giving rise to the idea of 3D printing. Since then, technology has advanced quickly, and it now includes a number of techniques as digital light processing (DLP), selective laser sintering (SLS), and fused deposition modeling (FDM).
How Do 3D Printers Operate?
Typically, a digital 3D model developed with computer-aided design (CAD) software serves as the basis for the 3D printing process. Then, using software for cutting, this model is separated into tiny horizontal layers. By interpreting these slices, the 3D printer starts to construct the thing layer by layer out of materials like plastic, metal, or even biological ones.
Technologies for 3D Printing
There are several 3D printing technologies on the market, each suited to certain uses and sectors. Thermoplastic filaments are melted and deposited in FDM, powdered materials like nylon are used in SLS, and liquid resin is cured by UV light in SLA.
