3D printing: why we started and where we’re going
Christopher Moir, MD
♢ Consultant - Division of Pediatric Surgery, Department of Surgery, Mayo Clinic, Rochester, Minnesota
♢ Professor of Surgery - Mayo Clinic College of Medicine
♢ Consultant (Joint Appointment) - Department of Pediatric and Adolescent Medicine, Mayo Clinic, Rochester, Minnesota
Following a 99-day hospital stay and a surgery that lasted more than six hours, a pair of formerly conjoined twins is recovering from the operation that separated them. Before the surgery, 5-month-old conjoined twins Abygail and Madysen Fitterer, of Bismarck, N.D., were joined at the chest and shared their front chest wall. The insides of their bodies were so intertwined that their livers had nearly fused into a single organ. And the surgeons said Madysen's heart was halfway inside her sister's chest. Despite these complexities, a surgical team at the Mayo Clinic in Rochester, Minn., led by pediatric surgeon Dr. Christopher Moir succeeded in leaving each of the girls with the organs necessary for their survival.

3D Printings in Clinical Applications
Jing-Jing Fang, PhD
♢ Professor, Mechanical Engineering, National Cheng Kung University, Taiwan
Prof. Jing Jing Fang had long time collaboration with surgeons from National Cheng Kung University Hospitals, she developed a generic medical image processing software package for oral and maxillofacial surgery, with clinical diagnosis of spinal lesions, pre-operative planning, and surgical aids. Her research items included: Computer-aided medical imaging software development, image processing and computer graphics technology were used to develop Medical Imaging Processing software with basic features including the capture of CT, X-ray, MRI and other medical images, 3D computer reconstruction models from tomography, simulations for bone cutting and removal, automated best symmetry plane search, symmetry value assessment, oblique tomography re-calibration, manual symmetry plane configuration, production of mirror symmetrical models, building implant profiles, etc. When combined with lithography, the software produces planning 3D skull models. She also interests in Computer-Assisted Image-guided Surgical Training. Using pairs of x-rays from cases of spinal fixation device use to correct scoliosis or bone spur removal, we designed an x-ray positioning system to help train interns and residents in Pediclevertebral positioning. This study was conducted in cooperation with Dr. Rui-Mo Lin, Orthopedics department of National Cheng Kung University Hospital (Dean of National Cheng Kung University Hospital Touliu Branch, Currently, Superintendent of Tainan Municipal An-Nan Hospital-China Medical University).

3D Bio-Printing for Regenerative Medicine
Jerry Fuh, Ying Hsi, PhD
♢ Founding Co-Director, NUS Center for Additive Manufacturing(AM.NUS)
Dr. Jerry Fuh is a Professor at the Department of Mechanical Engineering, National University of Singapore (NUS). He is a Fellow of SME and ASME and a licensed PE from California, USA. He obtained his BS degree in Mechanical Engineering in 1980, MBA in Production Management in 1982, from Taiwan and an MS in Manufacturing in 1985 and PhD degree in Mechanical and Aerospace Engineering in 1992 from University of California, Los Angeles (UCLA), USA. He worked for 5 years in California, USA across the aerospace, disk-drive automation and CAD/CAM industry before joined NUS as Lecturer in 1993. Dr. Fuh has devoted himself to the research of additive manufacturing processes or 3D Printing (3DP) since 1995. Over S$20M+ external and internal grants related to the 3DP programme were jointly secured from his contributions. As a result of his research on selective laser melting for 3DP, more than 60 international-refereed papers were published related to the 3DP processes and 40 to the material developments, together with 4 book chapters, 3 monographs of which one as an earlier metal-based 3DP book entitled “Laser-Induced Materials and Processes for Rapid Prototyping” published by Kluwer Academic, MA in 2001. Owing to his research reputations, he has been invited as Visiting and Guest Professors and Scholars for many overseas universities, e.g. Stanford U, and George Inst Tech from US; PKU, Xian JTU, HUST, WUT, and Harbin IT from China; STUST, YZU and NTU from Taiwan, etc.
In his over 20 years of career at NUS, he and his colleagues started-up MicroSoft Technologies in 1997 to commercialise an innovative injection mould design software called IMOLDTM which is one of the earliest and has been used by more than 40 overseas tooling companies as a benchmarking standard for any automated mould design software. Furthermore, a multi-material 3DP system named “high-temperature laser manufacturing system” (HTLMS) was patented and commercialised by a local contract manufacturer in 2003. This novel HTLMS enables the rapid fabrication of not only metallic parts but also organic and inorganic parts, with the objective of rapidly making precision metallic components for tooling use. In 2005, he received the IES Prestigious Engineering Achievement Award for “Development of Rapid Prototyping Technologies for Precision and Biomedical Engineering” from the Institute of Engineers, Singapore (IES) in recognition of outstanding engineering skills which has made notable contributions to progress engineering in Singapore. Dr. Fuh has published over 350 technical papers (over 6,500 citations and 45 h-index from Goggle Scholar) and delivered over 40 invited talks overseas in manufacturing related area. In 2016, he and his colleagues established a 3DP-enable biomedical hub within the NUS premise across 5 different faculties, i.e., engineering, science, deign, dental and medicine, to be one of its few kinds to promote translational works on biomedical and health-care research under the NAMIC, EDB and University Funding of more than $20M.

CAD/CAM Facial Skeletal Surgery ~ Efficiency, Precision and Safety ~
Yuan-Chien Chen, DDS, MS
♢ President, Taiwanese Association of Oral & Maxillofacial Surgeons (TAOMS)

Computer Assisted Surgery (CAS) can be categorized into 3 subgroups, robotic surgery, navigation systems and CAD/CAM technology. However, robotics seemed to be more practical and limited to soft tissue dissection while navigation procedures are generally considered time consuming during preoperative setting.
The outcomes of utilizing computer-aid virtual planning(CAD) and additive manufactured cutting / positioning guides(CAM) as well as powerful ultrasonic apparatus (BoneScalpel TM by Misonix Inc, Farmingdale, NY, USA & BONEMED Surgery Unit TM, VIA-TECH Biomedical. Co. Ltd, Taiwan) with tissue selective cutting characteristics in a series of more than 100 patients underwent 2-jaw orthognathic surgery in the OMS department of China Medical University Hospital, Taichung City, Taiwan from Jul. 2014 ~ Jul. 2017 will be presented. Both efficiency and preciseness have been significantly improved by applying CAD/CAM technology in our case series especially for those suffered from obvious asymmetric situations where complicated pitch, roll & yaw are inevitable, in which traditional 2D analysis is certainly insufficient and not reliable. The same CAD/CAM concepts are also applicable to cosmetic facial bone contouring and selected cases of benign jaw bone tumor resection with immediate reconstruction through trans-oral approach.
