A method to reproduce an original object includes receiving a 3D model of the original object; forming a reformable master shape from the 3D model by using a computer controlled shape actuator; impressing the reformable master shape into a reformable material to form a custom mold, the reformable material having a material state that is reversible between a solid condition stable force-resisting state and a flowable state by addition of a transition liquid; pouring a material into the custom mold while the reformable material is in the stable force-resisting state and fabricating a copy; adding the transition liquid to the reformable material to change the state of the reformable material from the stable force-resisting state to the flowable state; and reusing the reformable material to form another custom sole once the reformable material is in the flowable state.
