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.
