RAPID PROTOTYPING - CONCEPTS, TECHNIQUES, APPLICATIONS AND FUTURE TRENDS
|
| |
|
Summary :
|
|
DURING LAST YEARS A NEW FAMILY OF MACHINES HIGHLY INNOVATIVE HAVE ENABLED, WITH TECHNOLOGIES AND DIFFERENT MATERIALS, TO PRODUCE A PROTOTYPE OF A MODEL IN AN ACCURATE AND FAST WAY STARTING FROM THE SOLID MODEL GENERATED IN THE CAD SYSTEM. SUCH MACHINES, KNOWN AS RAPID PROTOTYPING MACHINES, ALLOW TO OBTAIN FINISHED PARTS WITH COMPLEXITY AND DETAILS THAT WOULD BE DIFFICULT BY CONVENTIONAL MACHINING PROCESS OR WOULD REQUIRE COMPLEX OPERATIONS IN NUMERICALLY CONTROLLED MACHINES. ALSO, IN SOME CASES THESE TECHNIQUES ALLOW TO OBTAIN A TOOLING THAT CAN BE DIRECTLY USED IN THE PRODUCTION PROCESS. THIS TECHNOLOGY ALLOWS THE COMPANIES TO DEVELOP NEW PRODUCTS FASTER (SMALLER TIME-TO-MARKET) AND WITH LOWER COSTS, AND MAINLY, WITH AN INCREMENT IN THE QUALITY BY MEANS OF A BETTER EVALUATION OF THE PROJECT. IT ALSO DECREASES THE UNCERTAINTIES AND RISKS.
THIS WORK PRESENTS A LITERATURE REVIEW OF THE MAIN ASPECTS OF THE RAPID PROTOTYPING TECHNOLOGY SUCH AS CONCEPTS, TECHNIQUES AVAILABLE, APPLICATIONS WORLDWIDE AND IN BRAZIL, AS WELL AS FUTURE TRENDS. THE MAIN OBJECTIVE IS TO MAKE THE MECHANICAL DESIGNERS AWARE OF THE TECHNOLOGY AND OF ITS POTENTIAL TO REDUCE COSTS AND TIME-TO-MARKET.
KEYWORDS: RAPID PROTOTYPING, PRODUCT DEVELOPMENT, CAD APPLICATIONS
