The effect of injection parameters on dimensional accuracy of wax patterns for investment casting
Thermal expansion and hot deformation are two phenomena causing dimensional errors in investment casting. This error occurs in dimensions between the die and wax pattern. Therefore, the wax's thermo-physical and thermo-mechanical properties, the metal die features, and the process parameters affect the dimensions of the wax pattern. Some important effective process parameters are the injection ...
متن کاملOptimization of Dimensional Deviations in Wax Patterns for Investment Casting
Investment casting is a versatile manufacturing process to produce high quality parts with high dimensional accuracy. The process begins with the manufacture of wax patterns. The dimensional accuracy of the model affects the quality of the finished part. The present study investigated the control and optimization of dimensional deviations in wax patterns. A mold for an H-shaped wax pattern was ...

متن کاملCustomized Cranioplasty Implants Using Three-Dimensional Printers and Polymethyl-Methacrylate Casting
OBJECTIVE The prefabrication of customized cranioplastic implants has been introduced to overcome the difficulties of intra-operative implant molding. The authors present a new technique, which consists of the prefabrication of implant molds using three-dimensional (3D) printers and polymethyl-methacrylate (PMMA) casting. METHODS A total of 16 patients with large skull defects (>100 cm(2)) un...
متن کاملUniversal API for 3D printers
With this research we propose the implementation of a overlay restful API for 3D printers to expose these machines to the Internet for utilization within cloud services. This is to abstract the underlying communication structure and means for accessing and controlling a 3D printer resource which is performed in one of three ways. The ®rst method of accessing and controlling a 3D printer is via ...
