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.

Researchers at Sandia National Laboratory in Albuquerque, NM, are ecstatic over the endless possibilities of rapid prototyping for speeding up computer-aided design and manufacturing. Their report at the Rapid Prototyping and Manufacturing Conference in May 1993 on the modeling of a bicycle crank arm highlighted the advantages of rapid prototyping over traditional techniques. The experiment, which used the stereolithography technique and the selective laser sintering approach, yielded production-like prototypes in just five days. Conventional methods usually take several months. In a related development, the process' speed improvement was instrumental in winning over a customer of Sundstrand Aerospace's Electric Power Div. The customer had asked for a current-transformer/electromagnetic interference module to be repaired in four months' time. Rapid prototyping enabled Sundstrand to make a model one month after the project's start.

Valencia, CA-based 3D Systems is offering its Stereolithography Contour (SLC) file format for free to rapid prototyping designers. The file format is a 'two-and-a-half-dimension contour representation' of components which is generated from computer-aided-design data. Unlike the standard STL file format, the SLC eliminates tesselation and data errors. This, in turn, results in smoother parts and faster fabrication times.
