Subsequently, another surgical procedure called cranioplasty is carried out to fix an implant or bone flap in patients who have undergone DC. In this paper, an automatic design methodology for additive manufacturing of a PSCI (patient-specific cranial implant) has been proposed. The input is the DICOM digital data from a CT scan and the output is the STL file geometry of the cranial implant. The proposed method has been tested and validated using real de-identified DICOM data, and the resultant implant was 3D printed and fit to the skull of a cadaver. The key contribution made in this paper is the complete automation of the design of a PSCI based on the skull’s unique geometry using a combination of image-processing and computational geometry techniques...

This technology is increasing the rate of innovation with new lightweight and sustainable designs and dramatically reducing the time from product ideation (design) to realization (manufacturing). Makerspaces are being built all over the world, especially in academic settings and students have 3D printers readily available to design and produce innovative ideas on the spot. The University of Cincinnati (UC) is partnering with Siemens PLM Software to create students who are ready for the digital workforce of the future considering the entire product lifecycle. UC is developing curriculum to teach the fundamentals of Additive Manufacturing using Siemens PLM software as a foundation using a cradle to cradle approach. Students will realize the idea of a ‘digital thread’ that connects a product design to its production environment using fast product/process simulations using a cradle to cradle approach. They will also become aware of simulation tools required for assessing and iterating the performance attributes of the process and the product between the ideation and realization phases to create a ‘digital twin’ of that product. This will help prepare students for Industry 4.0.
