1. A new manufacturing process for four dimensional (4D) printed parts 

This is a new process or method of embedding NiTinol sheet within a 3D printed part which will actuate when heat is provided to it. The process will give rise to the effect of novel 4D printing technology. The process detail process plan is shown in the flow chart attached with this document. This process can be used to manufacture products that can change its shape and structure upon contact with external stimulus which is heat in this case. This novel process will solve two major problems with 3D printed parts that is they are static and the built platform is limited. 4D Printed part made by sandwich of plastic and SMA sheet will provide dynamic parts/structures as well as using design considerations active origami can be made which will can transform after being printed. In comparison with other smart materials that can be used for 4D printing application, it has high strain recovery, high melting point, low cost, excellent corrosion resistant, easy shape programming procedure and easy control of recovery temperature. These are also biocompatible and biodegradable and hence gained extensive research interests recently in various areas such as medical, civil, military etc. The complete process includes the 3D printing from a CAD file that is being sliced using slicing software which specifies the details of the material configuration and its properties. This process is highly flexible in terms of design considerations and convenience of operation during the creation of a functional component. The SMA we used to be a nitinol sheet, whose shape recovery is thermally triggered.
