Hi-tech investment castings has installed a rapid prototyping machine. This machine works on computer software and makes resin patterns, which can be subsequently coated with ceramics to prepare shell and casting samples. This process is capable of producing resin patterns in few hours and sample castings in 8-10 days without having to invest in costly die/tool making. Casting having maximum size upto 300 * 300 mm can be conveniently made through this process. This process is particularly useful where the design of casting needs to be certified.
