What is it about?
3D printing allows complex objects to be made, some finishing steps are normally required, one thing which is commonly done is to create screw threads for making connections. We showed that screw threads can be 3D printed and they are just as strong as normal threads.

Why is it important?
Being able to complete more of an object by 3D printing reduces time spent on finishing objects, and by printing 3D threads these are potentially much more accurately aligned to the original design. In our example we focussed on plates used to fix bone fractures, these are usually held in place by locking screws. If the locking screws are not aligned correctly they represent a potential weak point.
