Inkjet printing of gelatin as a biomaterial: a review

In recent years, much effort has been invested in turning ink jet printing into a versatile tool for various industrial manufacturing processes, in order to accurately deposit minute quantities of materials. Examples of polymer inkjet printing are given, including the electronics, three- dimensional printing, and oral dosage forms for controlled drug release. Ink jet printing has proven to be a robust process for biosurface engineering due to its high printing resolution, low cost, repeatability and speed. In this review we have studied the possibility of using gelatin as a bioink for ink jet printers.
