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.
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.

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.
RAPID prototyping, PROTOTYPES, MANUFACTURING processes, ENGINEERING design, and DIGITAL technology
The article discusses the advantages of using manual methods of rapid prototyping. It states that manual methods can generate metal parts faster and cheaper than using modern prototyping technology. It indicates that digital prototyping technology provides new ways of doing things efficiently but it can be expensive.
RAPID prototyping, HIGH technology industries, THREE-dimensional printing, CARBON nanofibers, 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.
Focuses on issues that need to be addressed in outsourcing for rapid-prototyping (RP) service. Use of a prototype work before considering purchase of the machine; Selection of a rapid-prototyping vendor with multiple RP technologies; Significance of equipment maintenance.
The article offers helpful insights on how to deal with shops that provide rapid prototyping (RP) services. The best RP firms choose the right process in the customer's best interest, turn parts around fast, and have a solid business history. Choosing a trustworthy bureau entails asking the firm on how long it has been in the business, what services it offers, and the age of its equipment. It is also helpful to be cautious of online quoting pitfalls. INSETS: What about start-ups?;Common DDM lingo.
