There are several technologies for rapid prototyping, a manufacturing technique in which the prototype of a part is created in hours rather than weeks. Rapid prototyping systems use three dimensional computer-aided design (CAD) files, slicing the image into cross sections and constructing layers of solid material, bonding each to the one before it. 3D Systems Inc $385,000 SLA 190 uses stereolithography and focuses an ultraviolet light onto a liquid polymer. It can produce a 20X20X20 inch part in 3 hours. Stratasys Inc's $178,000 3D Modeler uses fused deposition modeling to produce a 12X12X12 inch part in under five hours. Helisys' $110,000 LOM-2030 uses laminated object modeling to create a 20X30X20 inch part in 15 to 30 hours. Light Sculpting Inc offers the $129,700 LSI-1115MA which produces an 11X11X15 inch part at 40 seconds per layer. Quadrax Laser Technologies Makes the $195,000 Mark 1000 Laser Modeling System which uses laser modeling to produce a 12X12X12 inch part in six to twenty-four hours.

CAD/CAM, New Technique, Design, Optimization, Time to Market, Prototype, and CAD-CAM systems -- Innovations
Product manufacturers can save significant time and expenditure by creating realistic prototypes of products on a computer design system. These 'soft prototypes,' if properly implemented, may be used to effectively evaluate a proposed product's function, fit, producibility and reliability. The creation of soft prototypes is a viable alternative to the traditional method of constructing 'hard' working models of products, which is usually done in a serial manner as improvements are devised. Many firms spend the majority of time on a project between conceptualization and manufacture on prototyping, so anything that speeds up the process is beneficial. Proper use of soft prototypes can lead to higher product quality, lower costs, a shorter time to market and better hard prototypes. A variety of software is required for optimal prototyping, including solid modeling, visualization, analysis, design optimization, process simulation and rapid prototyping tools.

Designers of sporting goods and recreational equipment are using computer-aided design and manufacturing (CAD/CAM) software to markedly reduce product cycle times and production costs. Strategies for product developement usually involve two- and three-dimensional displays, solid modeling, finite-element analysis, prototyping, numerical control programming and production and designers are finding CAD/CAM can help during all stages. A squash and racquetball racket designer uses two- and three-dimensional features to fine-tune designs before having them prototyped and the program's modeling features may replace molds as a means of seeing what racquets will look like before production begins. CAD/CAM modeling and finite-element capabilities are assisting surfboard designers by replacing traditional styrofoam models with more symmetrically correct computer models. Bicycle designers find CAD/CAM-generated prototypes are more likely to be correct the first time they are created and therefore save time and money.

Toshiba Corp is using CADSI's Dynamic Analysis and Design System (DADS) to improve quality, reduce costs and shorten development times. The system's simulation and animation capabilities enable designers to predict the performance of mechanical designs and eliminate the time consuming build-test cycles involved with physical prototyping. DADS also performs many analyses, including assembly, dynamic, static, inverse dynamic and kinematic. Toshiba runs DADS on a Cray Y-MP supercomputer as a general-purpose computer-aided kinematic and dynamic analysis tool. DADS analysis is used to predict the dynamic characteristics of vacuum circuit breakers and gas circuit breakers. DADS will incorporate customized utilities and user-written subroutines. The software is saving Toshiba $100,000 per year and reducing development times for vacuum circuit breakers by three months.
