The development of new drugs and therapeutic treatments is a highly complex and elongated process beginning with cell culture studies which progress to animal models before the clinical trials are reached. On average, the development of a new type of medicine takes at least ten years with a likelihood of approval at 9.6%. These numbers can be improved by ensuring that the foundation for the drug is based on a clinically relevant system 1 . In this article, we will focus on how 3D printing bone can be a novel way to improve the drug discovery process for bone diseases by providing a way to evaluate them in vitro.
