There is currently a Japanese company that will print a 3D model of your fetus. Known as 天使の形 or “Shape of an Angel”. This service is said to cost around $1,200 and there are options such as key chains (of the fetus) as well.
Some people may view the printing of a fetus repulsive, yet when you compare it to a standard ultrasound image I think that it provides a more interesting view.
Also, there have been some developments on a larger scale. That is to print buildings using 3D printing techniques. These are primarily printed using recycled waste combined with concrete to “print out” walls for the construction of buildings.
Not limited to consumer related uses, 3D printing has provided benefit in the advancement of medicine as well. A woman who’s skull was excessively thick was surgically replaced with one that was 3D printed.
The application of 3D printing has come a long way and further possibilities are only limited by the imagination!
