The dimensional accuracy of shells and binders of investment casting which incorporation with selective laser sintering is investigated. The results show that the dimensional accuracy of colloidal silica is higher than that of ethyl silicate, and the dimensional variation rate of investment casting shells produced with colloidal silica is much lower than ethyl silicate shells. Moreover, colloidal silica possesses better performance on environmental protection and production cost control. These indicate that the comprehensive properties of colloidal silica are better than that of ethyl silicate. Meanwhile, the average dimensional variation rate of the single colloidal silica shell and the ethyl silicate-colloidal silica alteration shell was almost identical and it was much lower than that of the other shells which were produced in this study. This means two kinds of shells are optimized in all five types of shells studied in the aspect of dimensional accuracy. The unique properties of two shells show clearly direction to choose the type of shell.

The Cost

Rapid Investment Casting can overcome the cost involved in designing and fabrication of metal tooling for wax injection process. The present investigation is aimed to determine the effects of CAD model placement degree and size on the dimension error of prototype base on Selective Laser Sintering. The experimental results show that the dimension change law of length, width and height is different from each other, it mainly due to the intersection angle between important edge and forming plane. When the angle is 0° and 90°, staircase effect is smaller and dimension accuracy is higher, when the angle is 45°, the staircase effect is biggest and dimension accuracy is lowest. The CAD model size has significantly influence on dimension accuracy because of secondary sintering, when the model size is 86mm, the secondary sintering reduces to minimum, the dimension error is 0, the secondary sintering is more obvious with the decrease of CAD model dimension.
