3D Printing. 3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object, with material being added together (such as liquid molecules or powder grains being fused together). 3D printing is used in both rapid prototyping and additive manufacturing (AM). Additionally, 3D printing techniques may lead to potential advancements in the medical field as research on designing artificial organs for transplantation further develops. Organ printing can potentially lead to the creation of functional artificial hearts, heart valves, kidneys, livers, and other major organs to aid in the organ shortage crisis. Read more on 3D Printing
