ABSTRACT:
A method for rapid tool manufacturing comprising the steps of first building an SFF pattern made of plastic to be used to make a first die half. Then there is the step of spraying metal onto the pattern to form a first metal substrate. Next, there is the step of separating the substrate from the SFF pattern to form the first die half. Then there is the step of building a second SFF pattern to be used to make a second die half. Next, there is the step of spraying metal onto the second SFF pattern to form a second metal substrate. Then there is the step of separating the second metal substrate from the second SFF pattern to form the second die half. In a preferred embodiment, the method for rapid tool manufacturing the second die half is formed by first the step of building an SFF model of a part to be molded. Then, there is the step of inserting the model into the first die half. Next, there is the step of spraying metal onto the model in the first die half to form a second metal substrate. Then there is the step of separating the second metal substrate from the model and the first die half to form the second die half.
