An investigation of improving the dimention accuracy of parts produced by 3D-Prining with size from 10 to 100 mm

Abstract

   With the global competition for saving cost and time, Rapid Prototyping (RP) has emerged as a key enabling technology, with its ability to shorten product design and development time. Although RP has many advantages, it has also some disadvantages such as the accuracy of models or parts. Especially, the 3DPrinting method based on powder and binder has not very high accuracy in both dimension and surface finish. This work carries out an investigation of improving the accuracy of hollow parts in 3D printing for products with sizes from 10 to 100mm
