The craniopaqus twins who were born as conjointed twins last year in Children’s Hospital of Montefiore [CAHM], New York, underwent 20 hour surgery with the help of 3D Printing Systems. A highly specialized 3D Printed Model was created of the conjoined twins which guided the surgeons towards a successful surgery with perfect incisions. It has been 1 year now and they seem to be progressing perfectly normal over milestones of childhood.
