+## 3D Printing pros and cons
+
+3D printing allows you to run very complex job with much less design constraints compared to traditional manufacturing and 
+can be especially helpful in deign as well as operational uses in remote location such as the space station.
+In addition, the speed in which you can turn a digital design in to reality is a game changer for rapid prototyping.   
+
+However, for large batch manufacturing it is not cost competitive, it has much more limited materials and longer time 
+per part.  In addition while 3D printers have gotten a lot more user friendly they are not even close ot being "plug 
+and play by the average user in term of simplicity of use and reliability. 
+
+In summary current 3D printer technology is  a game changers for some use cases such as rapid prototyping, certain dental/medical 
+procedures and others. It will still require another round or two of evolution to take on main stream manufacturing.
