In a latest advancement in technology, researchers were successful in speeding up and smoothing the process of three dimensional or 3D printing further, with the help of a trick of chemistry. The innovation also showcased the ability of producing objects in minutes which previously took hours to complete.
Three dimensional printing techniques typically build a single layer at a time. Many even deposits globules of printing material in a way that is similar to laying down tiny layers if bricks. There are others who create the end product, by letting the ultraviolet rays to shine into a bath filled with liquid resins. The resin is solidified in the process. The partially solidified product is pulled upwards so that the light could process the layer below. Therefore, the whole process appears as if to emerge out of the bath.
But both the processes mentioned above, can consume several hours in a day to finally produce the complex structure.
In order to simplify the process involved in three dimensional printed a team led by Joseph DeSimone from the University of North Carolina located at Chapel Hill discovered a new and refined technique, to make the process continuous rather than dividing it into several fits and starts. The team manufactured the bottom of the container holding resin bath from a material which is likely a preamble to oxygen. Oxygen possesses the property to inhibit or hamper the solidification of resin, by creating a “dead zone”. This layer is thick as just tens of microns deposited in the bottom of the container. This is the level where the resin stays when ultraviolet rays glistens on it.
