Quick error comparisons of fabricated parts and an original CAD design is often a difficult yet important issue in product quality control. In this paper we present an integrated technique of 3D scanning with reverse engineering and rapid prototyping technologies. This will be applied to the entire quality control phase of quick response products during the manufacturing process. By using 3D scanning and reverse engineering technology in conjunction with rapid prototyping technology, the geometric data of components can be easily and rapidly measured and analyzed. The detailed report can be printed out directly to fulfill the requirement of total quality control for quick response products. The proposed technique is especially suitable for fragile or soft material made products, like thin shell or rubber parts. With its accuracy and ease of operation, this integrated method is able to help manufacturers improve their global competitiveness in the 21st century.
Rapid Prototyping (RP) technology is being widely used in diverse areas including mold manufacturing. However, the quality of RP parts is significantly affected by the property of adopted material and process parameters of the rapid prototyper. The aim of this paper is to investigate the powder material and to optimize the process parameters for Zcorp 402 3DP rapid fabricator. Taguchi's method was employed to investigate the possible process parameters including binder setting saturation value (shell & core), layer thickness, and location of made‐up parts. The experimental result shows that these optimal parameters can shorten parts building time and reduce the use of powder and glue about 20 per cent for ZP100 and 10 per cent for ZP11. Additionally, the quality of RP parts is also improved dramatically. The observation of experiments also shows that the parts made by ZP11 powder is difficult to clean up because of its starch‐based property.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
