Background

With the rather explosive development of 3D printing in the manufacturing industry the technique has gained some traction in the last years when it comes to the medical field.

The possibility of making custom, patient specific implants and tools for preoperative or educational purposes has shown great value in allowing to visualize complex anatomy, aid in surgical planning or training and lowering surgery time¹.

There is a wide range of readily available software programs and 3D printers that can provide the needed workspace for additive manufacturing ( 3D printing ), of which we will discuss in general and in particular about our setup.
