== Challenges: ==

Current state of challenges in organ printing is the slow processing speed of the organ printer. The organ printing technology requires high resolution and speed with a bioprinter, and higher resolution will end up with better control in the 3D microenvironment. The other biggest challenges in organ printing is the integration of vasculature. Without this vascularization, the 3D printing’s thick organs cannot transport nutrients, oxygen, and waste removal. Without this technology, it will lead to malfunction of the bioprinted organs. The technology must be developed in a way that it can transport oxygen and nutrients while extracting waste product.

== Patent System: ==

Since the organ printing is invention and innovation of technology, the scientists or inventors are able to grant patents to their technology. The 3D printing technology allows to copy any object technically, and concerns come from here where those objects are made without any authorization. The method of 3D printing is almost like building legos, and individuals might misuse the technology at low cost. In U.S. law, the patent owner accuses an individual who makes and sells/imports the patent object without authorization.
