Popis: Rapid Prototyping (RP) enables the quick production of physical models using three-dimensional Computer-Aided Design (CAD) data. Used in a wide range of industries, it allows companies to turn innovative ideas into successful end products rapidly and efficiently. RP systems, based on an additive manufacturing principle, emerged in 1987 with the introduction of the revolutionary stereolithography technology, a process that uses layer by layer photopolymerization of a light-sensitive liquid polymer, using laser technology. Lately, other RP technologies were introduced, such as Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS) and Laminated Object Manufacturing (LOM). The industry’s very first 3D RP system based on inkjet technology was introduced in 2000. The process begins with taking a virtual design from modeling or CAD software. The 3D printing machine reads the data from the CAD drawing and lays down successive layers of liquid, powder, or sheet material—building up the physical model from a series of cross sections. These layers, which correspond to the virtual cross section from the CAD model, are automatically joined together to create the final shape. RP uses a standard data interface, implemented as the STL file format, to connect between the CAD software and the 3D prototyping machine. The STL file approximates the shape of a part or assembly using triangular facets. RP systems produce 3D models within a few hours, depending on the type of machine being used and the size and number of models being produced.
