Recently there have been various articles on interesting things that have been made through printing. And in particular, objects created through the use of 3D printing have come into the world of technology. The reason I believe that this technological trend is interesting because the objects that are being printed here are microscopic.When created, these materials would be used to make essential things like biological tissue. With all the medical issues that impact our world today, any new innovation that seem to create another medical alternative seems like a great idea. This is an example of technology that affects others because later on it can provide those without medical options another alternative.This could do so much for the…show more content…
The beginning of 3D printing started in the 1980’s by an American inventor named Charles Hull (Glass&Ponsford,2014). What makes this trend new and relevant to past 4 years is the ability to integrate various different materials to make microscopic materials. Examples of possibilities that have come about because this micro technology include “ heart stents, microneedles for painless shots, gecko adhesives, parts for microfluidics chips, and scaffolds for growing cells and tissue”(Patel, 2013). These ideas could provide a lot of the medical world in terms of treatment.

Recently the newest section of 3D printing, microscale printing, has made waves in the technological advancements. One invention that seems extremely interesting is a bionic ear created by a group from Princeton University.This bionic ear is “functional ear that can "hear" radio frequencies far beyond the range of normal human capability”.Engineered by Assistant Professor of Mechanical and Aerospace Engineering Michael McAlpine and his team, integrated “antenna electronics with tissue within the highly complex topology of a human ear”. This team used the printer to infuse “matrix of hydrogel and calf cells with silver nanoparticles that form an antenna”. The cells gradually developed into the cartilage that made the ear(Sullivan, 2013). Another great development was the printing of retinal cells by Keith Martin of Cambridge University to form complex eye tissue. The cells used in these
