...>cases HeroBuilders.com >Abstract Emil Vicale, president of BBC (BBC) Design Group, used rapid prototyping technology (RPT) to build wax or plastic three-dimensional prototypes of his clients’ designs. But this same technology can be used to custom manufacture dolls. Shortly after September 11, 2001, Vicale Corporation, BBC’s parent company, purchased an e-commerce toy company. Vicale’s first action figure was made to honor the heroes who emerged from that event. Using RPT, he crafted a doll with the head of George W. Bush and the body of Arnold Schwarzenegger. Other figures followed. This case is about a design firm that used exploratory research to define a niche in the action-figure business. www.herobuilders.com >The Scenario Emil Vicale, president of HeroBuilders.com Corporation, thinks entrepreneurial. His industrial design company, BBC Design Group, has been operating for more than 20 years. One cornerstone of his design business is an innovative technology called rapid prototyping (RPT). RPT allows a designer to go from 3-D computer model to 3-D plastic or wax prototype in a matter of hours rather than the days, weeks, or months that prototypes using subtraction technology (carving) from wood, metal, or clay might take. As part of a growth strategy implemented shortly after September 11, 2001, Vicale finalized the purchase of an e-commerce toy company, ToyBuilders.com. This was his first venture into the manufacture of toys, although his design firm had done developmental...

...15, 2010 Riordan Manufacturing HRIS Analysis The ability to analyze and study the needs of an organization is an essential skill for a systems analyst. A systems analyst uses the concept of analysis and design to maintain and improve their information systems. The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently (citation). The first steps that need to be taken in systems improvement are research and analyzing the scope and feasibility of a new project. Systems Analysis Approach The information-gathering technique and design method proposed for this project is the Rapid Application Development method, acronym RAD. The RAD methodology is a process in which research of user requirements is compiled before producing any detailed system design documents. Using this approach decreases the time needed to design and implement new systems. Factors of Successful Analysis The Rapid Application Development method incorporates using three different approaches of systems analysis. These sub-approaches are Prototyping, Computer-Assisted Software Engineering Tools, and Joint Application Design. By using the three different perspectives, RAD streamlines the entire systems analysis and design process. Prototyping Prototyping is the building of a raw and small-scaled working model. This model is an easily modified...

...information systems are conceived, designed, and implemented using some form of systematic development process. In this process, end users and information specialists design information systems based on an analysis of the information requirements of an organization. Thus, a major part of this process is known as systems analysis and design. When the systems approach is applied to the development of information system solutions, a multistep process or cycle emerges. This is frequently called the information systems development cycle, also known as the systems development life cycle (SDLC). Steps involved and products produced in the traditional information systems development cycle: 1. Systems investigation - Product: Feasibility Study 2. Systems analysis - Product: Functional Requirements 3. Systems design - Product: Systems Specifications 4. Systems implementation - Product: Operational System 5. Systems maintenance - Product: Improved System 1. All the activities involved are highly related and interdependent. 2. Several developmental activities can occur at the same time. 3. Different parts of a development project can be at different stages of the development cycle. 4. Analysts may recycle back at any time to repeat previous activities in order to modify and improve a system being developed. 5. Developments such as computer-aided systems and end user development are automating and changing some of the activities of information systems development....

...June 2012 • www.Mojo3Dprinting.com • 10 CASE STUDIES A New Mindset in Product Design 3D printing can help bring better products to market faster By Stratasys Inc. What is 3D printing? The terms “3D printing” and “additive manufacturing” refer to processes that automatically build objects layer by layer from computer data. The technology is already well-used in many sectors including transportation, health care, military and education. Uses include building concept models, functional prototypes, factory tooling (such as molds and robot-arm ends), and even finished goods (such as aircraft internal components). The aerospace and medical industries in particular have developed advanced applications for 3D printing. 3D printing is sometimes referred to as “rapid prototyping,” but this term does not encompass all current uses for the technology. Materials used in 3D printing include resins, plastics and, in some cases, metal. 3D PRINTER Since 3D printing’s inception, system reliability and model quality have increased, resulting in diverse applications. At the same time, prices have gone down to the point where some systems are affordable even for small businesses. In a 2011 report, Wohlers Associates predicted that worldwide annual sales of additive manufacturing systems will reach 15,000 units by 2015 — more than double the 2010 rate. Lower-priced professional systems will drive most of this growth.1 In FDM Technology™, printer software on the user’s Windows network...

The only consensus, it seems, is that it needs to change fundamentally or it could all but disappear. At The New York Times, tough times have elevated IT-enabled innovation to the top of the agenda. A research and development group, created in 2006, operates as a shared service across nearly two dozen newspapers, a radio station, and more than 50 Web sites. “Our role is to accelerate our entry onto new platforms by identifying opportunities, conceptualizing, and prototyping ideas,” explains Michael Zimbalist, the company’s vice president of R&D. Zimbalist’s staff of 12 includes experts in rapid prototyping, specialists in areas like mobile or cloud computing and data miners who probe Web site data for insight into what visitors do. They work within a common framework based on idea generation, development, and diffusion throughout the business. Recent projects included prototypes for new display ad concepts, as well as BlackBerry applications for Boston.com and the expert site About.com. The team’s work is intended to supplement and support innovation taking place within the business units.

...MICRO-STEREOLITHOGRAPHY Authors : Ruchita Kulkarni, Kedar Malusare _____________________________________________________________________________ 1. INTRODUCTION 1.1 Rapid prototyping Rapid Prototyping (RP) can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data. What is commonly considered to be the first RP technique, Stereolithography, was developed by 3D Systems of Valencia, CA, USA. The company was founded in 1986, and since then, a number of different RP techniques have become available. Rapid Prototyping has also been referred to as solid free-form manufacturing; computer automated manufacturing, and layered manufacturing. RP has obvious use as a vehicle for visualization. In addition, RP models can be used for testing, such as when an airfoil shape is put into a wind tunnel. RP models can be used to create male models for tooling, such as silicone rubber molds and investment casts. In some cases, the RP part can be the final part, but typically the RP material is not strong or accurate enough. When the RP material is suitable, highly convoluted shapes (including parts nested within parts) can be produced because of the nature of RP. Fig 1. Rapid prototyping worldwide There is a multitude of experimental RP methodologies either in development or used by small groups of individuals. They are listed as given below.

...As the part of the curriculum, I had the opportunity to take in real data from an industry for the Optimization of transportation cost. The case study was to reduce the cost of transportation of a local industry to transport their products from various warehouses to their various supply points. It gave me my first experience as an engineer in which I reduced the cost of transportation of the particular industry by five per cent. I am also working on my project on “Multi objective optimization of Selective Laser Sintered (SLS) components using genetic algorithm”. The project aims at optimizing the process parameters of the SLS manufactured components using an algorithm by which a product can be made of superior mechanical properties rather than optimizing just one property and to bring Rapid Prototyping into main scale manufacturing of components. I was also able to co-author three international journal publications, one being on “the early cost estimate of a washing machine using Design for Manufacturing and Assembly (DFMA) Principles” and two others on Rapid Prototyping techniques, thereby reducing the machining time and the wastage of materials during manufacturing and the improving reliability of the products...
