The article reports on the development of additive manufacturing, more commonly known as three-dimensional (3D) printing. It is said that additive manufacturing is increasingly used to produce parts with greater speed, improved economics and performance. Earlier, additive manufacturing was primarily used to make prototypes of new products.
A childhood love of turbines led to the design and eventual 3D printing of unusual aircraft engine that blends three distinct technologies. Nino Caldarola, an application specialist at Autodesk reseller [...]

Rapid prototyping, Printing, Engineering equipment, Machine design, 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.

Gordon, Leslie New approaches to rapid manufacturing let almost anyone inexpensively produce parts, products, and prototypes. So says Ted Hall, founder of ShopBotTools in Durham, N.C. Perhaps you recall the [...]
The article focuses on the booming industry of additive manufacturing. According to NIST’s Brandon Lane, the technology is still relatively new, and maintaining quality control can be time-consuming and challenging. The build up of residual stresses which create cracks between layers and warping the piece is cited.
Rapid prototyping, Computer software, Prototypes, and Engineering design
Looks at materials and build techniques that change the way companies use rapid prototyping (RP) equipment. Information on some RP build improvements which include software revisions; Benefits of rapid prototypes; Description of the Z-Cast RP pattern process from Griffin Industries. INSETS: Accurate RP parts tell more in wind tunnel tests;Thin layers produce smooth surfaces.
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.

In recent years, the automotive and off-road industries have increasingly used modeling to simulate the operation of vehicles and subsystems prior to prototyping them. This saves time and money. But [...]
The article presents information on several new approaches for rapid prototyping. Neil Gershenfeld of the Massachusetts Institute of Technology established a few fabrication laboratories (Fab Labs) a few years ago in universities, colleges and housing projects. ShopBot CNC router is a digital fabrication machine developed by ShopBot Tools Inc. based in Durham, North Carolina, which provides a format for making several industrial machines and devices.
Rapid prototyping, Manufacturing processes, Three-dimensional printing, Fabrication (Manufacturing), and Nanofabrication
The article focuses on the move of additive manufacturing to replace conventional fabrication processes in critical areas ranging from aerospace components to medical implants. The possibility of the technology to become a target for malicious attacks is mentioned. The validation technique developed by researchers at Georgia Institute of Technology and Rutgers University is emphasized.

Light Sculpting Inc. -- Innovations and Electronic components industry -- Innovations
Light Sculpting Inc's LSI1212 is based on the quick-layering (QL) technology. It hardens entire layers of polymer at once to support the manufacture of high-resolution components at speed that are unattainable by other rapid prototyping systems. QL constructs components on an open platform that lets designers access parts as the machine constructs them. It supports on-line cleaning and can be retrofitted with a slicing software to examine part geometries.
