RAPID prototyping, ENGINEERING equipment, MACHINE design, PRINTING, and SINTERING
The article presents survey findings on the capability of rapid-prototyping (RP) technique for micromolded components in a machine design in the U.S. The gathered data primarily focuses on the dimensions, features and performance of various RP technologies, considering the technology requirement in the medical, optical and microelectronics industries. Among the assessed RP tools include stereolitography, 3D printing or inkjet printing, and selective laser sintering.
RAPID prototyping, LITHOGRAPHY, MODELING (Sculpture), SINTERING, and MOLDING (Founding)
The article presents several rapid-prototyping techniques for micromolded parts which include stereolithography (STL), fusion-deposition modeling (FDM) and selective laser sintering (SLS). It says that the first technique utilizes liquid ultraviolet (UV) curable photopolymer resin touched on a UV laser beam. The second technique extrudes a modeling material through a nozzle while the last one uses a high-temperature laser to melt metal into a three-dimensional (3D) part.
THREE-dimensional printing, RAPID prototyping, CARBON nanofibers, HIGH technology industries, and SINTERING
The article discusses the increasingly use of additive manufacturing (AM) to make production parts. The forecast on the possibility of AM leveraged to build stronger objects from materials filled with carbon nanofiber is cited. According to Carol Tolbert, manager of the Manufacturing Innovation Project, they are using direct laser sintering to develop a subscale multielement injector for a rocket engine and to minimize testing cost. The standardization efforts of AM is stated.
RAPID prototyping, SINTERING, INDUSTRIAL lasers, MANUFACTURING processes, and ENGINEERING design
The article focuses on electromechanical component supplier Festo AG's Festo Fast Factory (FFF) service. It states FFF includes four rapid-prototyping technologies, including selective laser sintering of plastics, fused-deposition manufacturing, and laser melting for metals, along with a staff of engineers and technicians that can create prototypes with properties of mass-produced products. It comments on the use of additive manufacturing to increase flexibility for design engineering.
