This week I have watched my second TED talk, "What if 3D printing was 100x faster?" This TED talk was presented by chemist and chemical scientist Joseph Desimone. He begins by explaining how you can create things with a 3D printer that you can't do with anything else. He uses a small but very complex 3D printed ball with, "...concentric geodesic structures." He even says that the ball can't be manufactured by traditional manufacturing techniques. He then explains how 3D printing is "...actually 2D printing over and over again." and to created a 3D printed ball like the one in the picture above, it takes between 3-10 hours...and with that being said Joseph DeSimone is going to do it on stage in 10 minutes with his new invention. This invention was inspired by the "terminator 2 scene of T-1000" ,specifically the scene where T-1000 arises out of a puddle of metal and forms into an object. DeSimone thought "why couldn't a 3D printer operate in this fashion?" So 2 other material scientists and himself were inspired and started to brain storm. They first looked at all the bad characteristics in normal 3D printers. The first being it "takes forever" to print the finished object , the second and third being that materials are "far to limited" and also printed parts are mechanically weak. They then thought about how they can harness light + oxygen to produce parts faster then usual. He quickly explains how light can take a resin and convert a liquid into a soild but oxygen "inhibits" that process. So they developed a machine they call C.L.I.P (Continuous Liquid Interface Production) The machine has a reservoir that holds the material that the finished product will be made of. The reservoir has a "oxygen permeable window" that allows light from a projector at the bottom of the machine to help speed the process. The last but important part of the machine is a platform that will pull the object out of the liquid. In this machine they are able to control the 3D model, the material, light, and oxygen to give the best end result. If you are wondering how it knows what to print well they use a computer software that they model the object in and then send it to the 3D printer. Now this isnt just for making toy balls, it can also be used to make car parts or even airplane parts that have a high strength to weight ratio.
I was immediately intrigued when I started watching this. Mostly because I myself have always known about 3D printing but I had no idea how beneficial it can be. DeSimone really explained everything well in this TED talk. I believe that 3D printing should be taken more seriously. Not only that but also for manufactures to start getting inspired and maybe one day make a 3D printing devise that can print in a matter of minutes or even seconds.
In conclusion to all of this after watching DeSimones TED talk I became even more interested. Hopefully we will live to see the day where 3D printing is something of the norm like how most people have regular printers.
