About Rapid Prototyping Services

Rapid prototyping services automate the fabrication of prototype parts from three-dimensional (3D) computer-aided design (CAD) drawings. These physical models convey more complete information about a product, and earlier in the development cycle. Although conventional prototyping may take weeks or even months, rapid prototyping services can offer turnaround times of just several days. By guiding a product from concept to market quickly and inexpensively, rapid prototyping services can help customers remain competitive while controlling costs. Selection criteria for rapid prototyping services include capabilities, additional services, geographic location, and quality standards or approvals. Other terms used for these companies include desktop manufacturing, automated fabrication, tool-less manufacturing, and free-form fabrication. 

Rapid prototyping services use technologies such as digital light processing (DLP), stereolithography, fused deposition modeling (FDM), and laminated object manufacturing (LOM). Digital light processing (DLP) services use a digital mirror to polymerize photosensitive resins. Unlike stereolithography, a process which uses an ultraviolet (UV) laser for curing, DLP uses visible light and special visible light-sensitive resins. Fused deposition modeling (FDM) services heat filaments of thermoplastic polymers and squeezes them from a tube to form layers. Machines range from fast concept modelers to slower, high-precision equipment. FDM materials include polyester, ABS, elastomers, and investment-casting wax.  Rapid prototyping services that perform  laminated object manufacturing (LOM) build 3D objects based on 3D geometric data.
