3D Printing Essay
So how does 3D printing work? A 3D printed object is built up one layer at a time from bottom-upwards by repeatedly printing over the same cross-sectional area. After that these layers are arranged on top of each other and as a result forming a solid 3 dimensional object. 3D printers work automatically by reading digital files from the computer called CAD (Computer Aided Design) files. These files are created using a 3D modeling program in the computer. Like every printer it has to use some form of ink. However, a 3D printer works slightly differently as it uses various materials such as polymers, plastic and maybe even metals as “ink” to print the object.
Now u may be thinking what are 3D printers used for, and more importantly how do they contribute to better healthcare? Well having the ability to print almost anything, Andreas Herrmann of the University of Groningen in the Netherlands and his colleagues are researching on …show more content…
This is because further tests has to be done as the team only left the samples in the saliva and bacterial mix for only 6 days. “For clinical usage we need to extend this, and investigate the compatibility with toothpaste,” says Herrmann. Moreover the process of 3D printing is very long which is about 1 hour since teeth have a high degree of detail. Also, the team needed to make sure that the plastic is strong and rigid enough to be used as a
